Upon completion, students will be able to understand basic statistics, organize information, create charts, analyze simple datasets, and make decisions based on data.
Welcome to the exciting world of Statistics!
Statistics helps us collect information, organize it, understand it, and use it to make good decisions.
Every day, people use statistics without even knowing it. Teachers use it to record test scores, football coaches use it to track goals scored, and shop owners use it to know which products sell the most.
Statistics is the science of collecting, organizing, studying, and understanding information.
Imagine your teacher asks the class: "What is your favorite fruit?"
Some students choose apples, some choose oranges, and others choose bananas.
Counting everyone's answers and finding the most popular fruit is an example of statistics.
Data is information that we collect.
Data can be numbers, words, pictures, or answers to questions.
Data helps us make better decisions.
Suppose a school wants to buy sports equipment.
The school asks students which sport they like most.
If most students choose football, the school may buy more footballs.
The school used data to make a smart decision.
There are two simple types of data:
This data uses numbers.
This data uses names or groups.
Data is everywhere!
When your teacher takes attendance, they are collecting data about who is present.
Collecting data means gathering information.
Let's ask five friends their favorite fruit.
| Friend | Favorite Fruit |
|---|---|
| Tolu | Apple |
| Amina | Banana |
| John | Apple |
| Mary | Orange |
| David | Apple |
From this table, Apple is the most popular fruit.
Organizing data means putting information in order.
Organized data is easier to understand.
Apple, Banana, Apple, Orange, Apple
| Fruit | Count |
|---|---|
| Apple | 3 |
| Banana | 1 |
| Orange | 1 |
Statistics helps us:
If a football team scores more goals every week, statistics helps us see that the team is improving.
A teacher asks students their favorite subjects.
| Student | Favorite Subject |
|---|---|
| Tolu | Mathematics |
| Amina | Science |
| John | Mathematics |
By looking at the data, we can see that Mathematics is the most popular subject.
Fill in the blanks:
Ask five classmates their favorite animal.
Create a table showing:
Which of these are data?
Identify whether each is Number Data or Category Data.
Conduct a survey in your class.
Ask students: "What is your favorite school subject?"
Create a table showing all answers and identify the most popular subject.
Collect data from 10 people about their favorite sport.
Organize the answers into a table and determine:
In Module 1, we learned that data is information that we collect.
But where does data come from?
Before we can study data, we must first collect it. Collecting data means gathering information from people, places, or things.
In this module, we will learn different ways to collect data and why collecting good data is important.
Data collection means gathering information.
People collect data every day without realizing it.
Imagine your teacher wants to know the favorite fruit in your class.
She asks every student: "What is your favorite fruit?"
The answers collected are called data.
Teacher | |---> Apple |---> Banana |---> Orange |---> Apple |---> Mango Collected Answers = Data
We collect data to help us make better decisions.
Suppose a school wants to buy sports equipment.
Students are asked their favorite sport.
If most students choose football, the school may buy more footballs.
Favorite Sport Survey Football = 15 Students Basketball = 5 Students Tennis = 3 Students Result: Buy More Footballs
Observation means watching carefully and recording what you see.
During break time, a teacher watches students and counts how many are playing football.
Playground Football ⚽ = 12 students Running 🏃 = 6 students Skipping Rope = 4 students The teacher observed and recorded the data.
A survey is when we ask many people the same question.
Ask 10 classmates: "What is your favorite subject?"
| Student | Favorite Subject |
|---|---|
| Tolu | Mathematics |
| Amina | Science |
| John | Mathematics |
An interview is when we ask someone questions and record their answers.
A student interviews the school librarian.
Question: What is the most borrowed book? Answer: Story Books
Student 🎤 ---> Librarian Question ---> Answer Information Collected
A questionnaire is a list of questions that people answer.
Favorite Food: __________ Favorite Sport: __________ Favorite Subject: __________
The answers become data.
After collecting data, we must record it carefully.
| Name | Favorite Color |
|---|---|
| Tolu | Blue |
| Amina | Red |
| David | Blue |
Writing data neatly helps us understand it later.
Collecting data carefully is like measuring ingredients when baking a cake.
If you use the wrong measurements, the cake may not taste right.
Let's collect data about favorite pets.
| Student | Favorite Pet |
|---|---|
| Tolu | Dog |
| Amina | Cat |
| David | Dog |
| Mary | Dog |
We can see that Dog is the most popular pet.
Fill in the blanks:
Ask 5 classmates: "What is your favorite cartoon?"
Record the answers in a table.
| Classmate | Favorite Cartoon |
|---|---|
Look around your classroom and count:
Record your answers in a table.
Conduct a survey about favorite sports.
Ask at least 10 people and record their answers.
Find:
Create your own questionnaire with 5 questions.
Ask your friends to answer the questions.
Record all answers neatly in a table.
In Module 2, we learned how to collect data using surveys, observations, interviews, and questionnaires.
After collecting data, the next step is to organize it.
Organizing data helps us understand information quickly and easily.
Organizing data means arranging information in a neat and orderly way.
Imagine all your toys are scattered around your room. It would be difficult to find your favorite toy.
But if you arrange them neatly in boxes, finding a toy becomes much easier.
Data works the same way.
Messy Toys ➜ Hard to Find Organized Toys ➜ Easy to Find Messy Data ➜ Hard to Understand Organized Data ➜ Easy to Understand
We organize data because it helps us:
Suppose 10 students tell us their favorite fruits.
Apple, Banana, Apple, Orange, Apple, Mango, Banana, Apple, Orange, Apple
This information is difficult to understand at first glance.
Sorting means arranging information in order.
Before Sorting: Banana Apple Orange Apple Mango After Sorting: Apple Apple Banana Mango Orange
Sorting makes data easier to study.
Grouping means putting similar items together.
Favorite Fruits Apple Apple Apple Banana Banana Orange Orange Mango
Now it is easier to see which fruit is most popular.
A frequency table shows how many times something appears.
| Fruit | Frequency |
|---|---|
| Apple | 4 |
| Banana | 2 |
| Orange | 2 |
| Mango | 1 |
Frequency means "how many times."
Tally marks help us count data quickly.
| Fruit | Tally | Total |
|---|---|---|
| Apple | |||| | 4 |
| Banana | || | 2 |
| Orange | || | 2 |
| Mango | | | 1 |
Each line represents one count.
Once data is organized, we can answer questions.
| Fruit | Count |
|---|---|
| Apple | 4 |
| Banana | 2 |
| Orange | 2 |
| Mango | 1 |
Most Popular Fruit = Apple
Least Popular Fruit = Mango
Let's organize information about favorite sports.
| Sport | Number of Students |
|---|---|
| Football | 12 |
| Basketball | 5 |
| Tennis | 3 |
Football ************ Basketball ***** Tennis ***
The stars help us quickly see which sport is most popular.
Survey Question: What is your favorite school subject?

In Module 3, we learned how to organize data using tables and tally marks.
Sometimes, looking at lots of numbers can be confusing. Charts and graphs help us turn numbers into pictures that are easy to understand.
In this module, we will learn how to read and create different types of charts and graphs.
A chart is a picture that shows information.
Charts help us understand data quickly.
Imagine your teacher asks students about their favorite fruits.
| Fruit | Students |
|---|---|
| Apple | 5 |
| Banana | 3 |
| Orange | 2 |
A chart can turn these numbers into a picture.
A graph is a special type of chart that uses lines, bars, or pictures to show data.
Graphs make it easier to compare information.
Numbers Only Apple = 5 Banana = 3 Orange = 2 Graph Apple ***** Banana *** Orange **
A bar chart uses bars to show data.

The tallest bar represents the most popular sport.
A pictograph uses pictures or symbols to represent data.
Each ⭐ represents 1 student.
Apple ⭐⭐⭐⭐⭐ Banana ⭐⭐⭐ Orange ⭐⭐
Pictographs are fun and easy to understand.
A pie chart is a circle divided into pieces.
Each piece shows a part of the whole.
Imagine a Pizza 🍕 Half Pizza = Football Fans Quarter Pizza = Basketball Fans Quarter Pizza = Tennis Fans
Pie charts help us see proportions.
A line graph uses points connected by lines.
It helps us see changes over time.
Number of books read each week:
Week 1 = 1 Book Week 2 = 2 Books Week 3 = 3 Books Week 4 = 5 Books
5 | * 4 | 3 | * 2 | * 1 | * 0 |________________ W1 W2 W3 W4
The line goes up because more books are being read.
When looking at a graph, ask:
Favorite Pets Dog = 8 Cat = 5 Bird = 2 Fish = 1
Dogs are the most popular pet.
Fish are the least popular pet.
Charts help us:
Imagine reading a book with 100 numbers. It may take a long time to understand.
A chart can show the same information in just a few seconds.
Survey Question: What is your favorite school subject?

Answer:
In the previous module, we learned how to organize data and display it using charts and graphs.
Sometimes we want to know what a "typical" value looks like. Statistics gives us special tools called Mean, Median, and Mode.
These tools help us understand data quickly.
Measures of Center help us find the middle or most common value in a group of numbers.
The three main measures are:
Imagine five friends scored marks in a quiz.
60, 70, 80, 90, 100
Mean, Median, and Mode help us understand these scores.
The Mean is what most people call the Average.
To find the Mean:
Scores: 10, 20, 30, 40, 50 Step 1: 10 + 20 + 30 + 40 + 50 = 150 Step 2: 150 ÷ 5 = 30 Mean = 30
10 + 20 + 30 + 40 + 50
↓
150
↓
Divide by 5
↓
30
The average gives us a value that represents the whole group.
Imagine five children have these sweets:
2, 4, 6, 8, 10
The average number of sweets is:
2 + 4 + 6 + 8 + 10 = 30 30 ÷ 5 = 6
So, on average, each child has 6 sweets.
The Median is the middle number when numbers are arranged from smallest to largest.
5, 10, 15, 20, 25
The middle number is:
5 10 15 20 25
↑
Median
Median = 15
Always arrange the numbers first.
Numbers: 20, 5, 15, 25, 10 Step 1: Arrange them 5, 10, 15, 20, 25 Step 2: Find the middle Median = 15
The Mode is the number that appears most often.
4, 6, 6, 8, 10
Number 6 appears two times.
The other numbers appear only once.
Mode = 6
4 → 1 time 6 → 2 times ← Most Common 8 → 1 time 10 → 1 time
Let's use one set of numbers:
5, 10, 10, 15, 20
| Measure | Answer |
|---|---|
| Mean | 12 |
| Median | 10 |
| Mode | 10 |
Notice that Mean, Median, and Mode may be different.
Number of books read by students:
3, 4, 4, 5, 9
Mean:
3 + 4 + 4 + 5 + 9 = 25 25 ÷ 5 = 5
Median:
3, 4, 4, 5, 9 Middle = 4
Mode:
4 appears twice Mode = 4
They help us:
A teacher can use averages to understand how well a class performed in a test.
Scores: 20, 30, 30, 40, 50
Mean:
20 + 30 + 30 + 40 + 50 = 170 170 ÷ 5 = 34
Median:
20, 30, 30, 40, 50 Middle = 30
Mode:
30 appears twice Mode = 30
Fill in the blanks:
Find the Mean:
10, 20, 30, 40, 50
Show all your working steps.
Find the Median and Mode:
8, 4, 6, 6, 10
Remember to arrange the numbers first.
Ask five friends how many hours they spend watching TV each week.
Record the answers and calculate:
Collect the mathematics scores of 10 students.
Calculate:
Which measure best describes the class performance?
In Module 5, we learned about Mean, Median, and Mode.
In this module, we will learn about percentages. Percentages help us understand parts of a whole.
Percentages are used everywhere:
Percentage means "out of 100."
The symbol for percentage is %.
Imagine you have a chocolate bar divided into 100 small pieces.
100 Pieces = Whole Chocolate Bar 50 Pieces = 50% 25 Pieces = 25% 100 Pieces = 100%
A percentage tells us how much of the whole we have.
100% means everything.
[██████████] All blocks filled = 100%
If you answer all 10 questions correctly in a test, you score 100%.
50% means half.
[█████-----] Half filled = 50%
If you eat 5 slices from a pizza that has 10 slices, you have eaten 50% of the pizza.
[███-------] About one-quarter filled
25% means one quarter of a whole.
[████████--] About three-quarters filled
75% means three quarters of a whole.
Let's find a percentage using a simple example.
A test has 10 questions.
Tolu answered 8 questions correctly.
Correct Answers = 8 Total Questions = 10 8 ÷ 10 = 0.8 0.8 × 100 = 80% Answer = 80%
Tolu scored 80%.
Schools often use percentages to show test results.
| Student | Score | Percentage |
|---|---|---|
| Tolu | 9/10 | 90% |
| Amina | 7/10 | 70% |
| David | 5/10 | 50% |
Shops often use percentages for discounts.
A toy costs ₦1,000.
The shop offers a 20% discount.
Original Price = ₦1,000 20% Discount You pay less than ₦1,000
Discounts help customers save money.
Schools use percentages to track attendance.
School Days = 20 Days Present = 18 18 ÷ 20 = 0.9 0.9 × 100 = 90% Attendance = 90%
This means the student attended most school days.
| Percentage | Meaning |
|---|---|
| 100% | Everything |
| 75% | Most |
| 50% | Half |
| 25% | A little |
| 0% | Nothing |
Percentages help us:
A class has 20 students.
15 students like football.
15 ÷ 20 = 0.75 0.75 × 100 = 75% Answer = 75%
Therefore, 75% of the class likes football.
Fill in the blanks:
Find the percentage:
Correct Answers = 6 Total Questions = 10
What percentage did the student score?
A class has 12 students.
9 students like basketball.
What percentage of the class likes basketball?
Survey 10 friends and ask: "Do you like football?"
Calculate:
Record your attendance for the next two weeks.
Calculate your attendance percentage.
Then answer:
In Module 6, we learned about percentages and how they help us understand parts of a whole.
In this module, we will learn how to compare data. Comparing data helps us see differences, similarities, patterns, and trends.
Every day, people compare data to make decisions. Teachers compare test scores, coaches compare team performance, and shop owners compare sales.
Comparing data means looking at two or more groups of information to see how they are different or similar.
Tolu scored 80 marks. Amina scored 90 marks. Who scored higher? Answer: Amina
We compared two scores to find the higher one.
The highest value is the biggest number in a group.
Test Scores 70, 85, 60, 95, 80
70 85 60 95 80
↑
Highest Score
Highest Value = 95
The lowest value is the smallest number in a group.
70, 85, 60, 95, 80
70 85 60 95 80
↑
Lowest Score
Lowest Value = 60
To find the difference, subtract the smaller number from the bigger number.
Amina = 90 Tolu = 80 90 - 80 = 10
Amina scored 10 marks more than Tolu.
90 █████████ 80 ████████ Difference = 10
Sometimes we compare groups instead of individual numbers.
| Sport | Students |
|---|---|
| Football | 15 |
| Basketball | 8 |
| Tennis | 5 |
Football is the most popular sport because it has the highest number.
Tennis is the least popular sport because it has the lowest number.
A pattern is something that repeats or follows a rule.
Books Read Each Week Week 1 = 2 Week 2 = 4 Week 3 = 6 Week 4 = 8
2 → 4 → 6 → 8 Pattern: Add 2 each time
This shows an increasing pattern.
A trend shows whether data is going up, going down, or staying the same over time.
Ice Cream Sales Monday = 10 Tuesday = 15 Wednesday = 20 Thursday = 25
25 | * 20 | * 15 | * 10 | * |________________ Mon Tue Wed Thu
Sales increased every day.
This is an upward trend.
Bar charts help us compare data quickly.
Favorite Fruits Apple = 10 Banana = 6 Orange = 4
Apple ********** Banana ****** Orange ****
Apples are the most popular fruit.
A teacher compares attendance records.
| Student | Days Present |
|---|---|
| Tolu | 18 |
| Amina | 20 |
| David | 16 |
Amina has the highest attendance.
David has the lowest attendance.
Comparing data helps us:

In Module 7, we learned how to compare data and find patterns.
In this module, we will learn about Probability.
Probability helps us predict what might happen in the future. It tells us how likely or unlikely something is to happen.
Every day, people use probability when they predict the weather, play games, or make decisions.
Probability is the chance that something will happen.
If you throw a ball into the air, what do you think will happen?
The ball will come back down.
The chance of the ball coming down is very high.
Probability helps us describe that chance.
Some events are very likely to happen. Some are unlikely.
| Event | Chance |
|---|---|
| The sun will rise tomorrow | Very Likely |
| It will rain chocolate | Impossible |
| You will toss a coin and get heads | Possible |
We use special words to describe probability.
Impossible → Cannot happen Unlikely → Probably will not happen Possible → Might happen Likely → Probably will happen Certain → Will definitely happen
Impossible ---- Unlikely ---- Possible ---- Likely ---- Certain
A coin has two sides:
Coin
_______
/ \
| HEADS |
\_______/
or
_______
/ \
| TAILS |
\_______/
When you toss a coin, there are only two possible outcomes.
Heads = 1 chance out of 2
Tails = 1 chance out of 2
Both outcomes are equally likely.
A standard dice has six sides.
1 2 3 4 5 6
If you roll a dice:
Each number has the same chance of appearing.
A certain event will definitely happen.
You throw a stone upward. The stone comes down. This is certain.
Probability = 100%
An impossible event cannot happen.
A fish riding a bicycle. This is impossible.
Probability = 0%
Probability is used in many areas of life.
Weather Forecast 80% Chance of Rain
This means rain is likely.
Toss a coin 10 times.
| Toss Number | Result |
|---|---|
| 1 | |
| 2 | |
| 3 |
Count how many times Heads and Tails appear.
Roll a dice 10 times and record the numbers.
Bag A: 5 Red Balls 1 Blue Ball Bag B: 3 Red Balls 3 Blue Balls
Which bag is more likely to give a red ball?
Answer: Bag A
Bag A 🔴 🔴 🔴 🔴 🔴 🔵 Bag B 🔴 🔴 🔴 🔵 🔵 🔵
A spinner has four equal sections.
Red Blue Green Yellow
Each color has the same chance of being selected.
Probability of getting Red = 1 out of 4.
Probability of getting Blue = 1 out of 4.
Fill in the blanks:
Write whether each event is:
1. The sun rises tomorrow. 2. A dog speaks English. 3. Rolling a 4 on a dice. 4. Rain falling during rainy season. 5. A fish driving a car.
Draw a coin and label:
Explain why both sides have the same chance of appearing.
Toss a coin 20 times.
Create a table showing:
Which appeared more often?
Put 5 red beads and 5 blue beads into a bag.
Without looking, pick one bead 20 times (return the bead each time).
Record your results and compare them with what probability predicted.
In Module 8, we learned about probability and chance.
In this module, we will learn how to use data to make predictions.
A prediction is an educated guess about what might happen in the future. Good predictions are based on facts and information, not just guessing.
A prediction is a statement about what you think will happen.
If dark clouds fill the sky, you may predict that it will rain.
Dark Clouds ☁☁☁
↓
Prediction
↓
It May Rain 🌧
You used information to make a prediction.
Predictions help us prepare for the future.
One of the best ways to predict the future is by looking at past data.
Ice Cream Sales Monday = 10 Tuesday = 12 Wednesday = 14 Thursday = 16
Sales increase by 2 each day.
Friday = 18
We used past data to make a prediction.
Patterns help us predict what comes next.
2, 4, 6, 8, ?
The pattern is +2.
Next Number = 10
2 → 4 → 6 → 8 → 10
A trend shows whether data is increasing, decreasing, or staying the same.
Books Read Week 1 = 1 Week 2 = 2 Week 3 = 3 Week 4 = 4
4 | * 3 | * 2 | * 1 | * 0 |________________ W1 W2 W3 W4
The trend is going upward.
Week 5 = 5 Books
Charts help us see patterns easily.
Football Club Attendance Week 1 = 20 Week 2 = 25 Week 3 = 30 Week 4 = 35
Attendance increases by 5 every week.
Week 5 = 40
Predictions are smart guesses, but they are not always right.
The weather forecast predicts rain.
Sometimes it rains. Sometimes it does not.
Prediction ≠ Guaranteed Result
Predictions help us prepare, but they do not tell the future perfectly.
A student records the number of pages read daily.
Monday = 5 Tuesday = 7 Wednesday = 9 Thursday = 11
The student reads 2 more pages each day.
Friday = 13 Pages
Surveys can also help us predict future events.
| Favorite Sport | Students |
|---|---|
| Football | 15 |
| Basketball | 5 |
If new students join the class, we may predict that football will remain the most popular sport.
Predictions help us:
Plant Growth Week 1 = 5 cm Week 2 = 7 cm Week 3 = 9 cm Week 4 = 11 cm
