Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-7	-3	7	8	9	14.0	2.8

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: 23.8

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -18.2

For the lines, you have the data necessary to plot the chart.
