Where is my variation coming from?

If you are having too much variation (or spread) in your data and you want to graphically determine where the variation is coming from, you can use the Multi Vari chart.

Probability Plots

Probability Plots help us visually determine if the data points follow a specific distribution.

Run Chart

Run charts can be used to check if the data is coming from a random population. It can be used to determine if the process is stable.

Interval Plot

An interval plot can be used to visually compare different groups where the primary metric of interest is whether the population mean of the different samples are similar?

Timeseries Plot

Time Series Plot is used to plot the values of a continuous variable over time. In this module, we will review a brief overview of time series plots.
