Descriptive Statistics in Six Sigma plays an important role. But, if we do not display that data in a way that can be easily understood, then it becomes useless to us or, worst yet, we might draw the wrong conclusions from it.
In this module, we discuss Descriptive Statistics as used in the Measure Phase of Six Sigma. We’ll go through the key measures that describe key characteristics of variation in a data set.
Descriptive Statistics includes measures of location and measures of dispersion.
