How Do I Create Run Charts in Excel Using SigmaXL?
A run chart is a fundamental quality tool used in Six Sigma and process improvement to display data points collected over time in sequence.
By plotting values against a mean or median reference line, run charts help teams detect trends, shifts, cycles, and other non-random patterns that signal process change.
SigmaXL makes it simple to create run charts directly in Microsoft Excel with automatic mean lines, and an optional nonparametric runs test for statistical validation.
Follow the step by step instructions below to build your first run chart using SigmaXL.

discussed later in Part N of Analyze Phase).
Click OK. A Run Chart of Overall Satisfaction with
Mean center line is produced.
