Calculated Deviation And Discard The Outliers.

In the editing group, click on the sort & filter icon. Create the range of the values calculated in step3 and step4. The trimmean function in excel can be used to calculate the average of a range of values while excluding a certain percentage of observations from the top and bottom of the dataset.

Identify The First Quartile (Q1), The Median, And The Third Quartile (Q3).

In our case, the quart is 1 because we wish to. Now calculate the value q2 * 1.5. The process of data entry can cause manual or automatic transferring errors, which may result in outlying values.
