There may be instances where you need to ghost a data point within your data as specific data points are not truly representative of the state of the measure.
When you ghost a data point in Simana it allows you to leave your data visible on the chart, but excludes the selected data from the calculation of the median (in the case of run charts), mean (in the case of control charts), and any control limits. It’s all done with the click of a button.
- Open the chart
- Click the ‘Data’ table in the top right
- Scroll along the data table until you reach the ‘Ghost’ column
- Locate the data point you wish you ‘Ghost’ and tick the box
- Your data point is now ghosted
