Identifying outliers allows you to know where to put focus Here are some principles used to identify outliers.
Keep the following things in mind:
Average/Mean – Most common output type but can be susceptible to limited results causing a skew in results
Median - The middle value of observations arranged in order of magnitude. Particularly helpful with quartile reporting.
Mode - The most frequently occurring value in a data set. Helpful to know where most performance is grouped
Range - The distance from the lowest data point to the highest data point. Best when used in tandem with the other methods.
