Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-69	-54	-59	-65	-51	-298.0	-59.6

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -38.6

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -80.6

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