Plot subgroup sample means against calculated 3-sigma control limits to spot an out-of-control process, then test two paired variables for correlation on a live scatter diagram with a best-fit line. Save and share your session.
Ideal for: NYSC corps members and job seekers rounding out the classic 7 QC tools for quality-management, Lean Six Sigma, or manufacturing/operations interview prep.
What you'll practice
Paste subgroup sample means and watch the mean line, UCL, and LCL calculate live at your chosen sigma level
See flagged points the instant a value falls outside the control limits, with an in-control/out-of-control verdict
Paste paired X/Y data on the Scatter Diagram tab to get a live plot, best-fit line, and Pearson correlation coefficient
Save and share your finished control-chart-and-scatter session
