Three useful checks, kept deliberately short.

What this result includes

The result reports all four measures and the sorted values.

A practical example

Values 4, 7, 7, 9 and 13: Sort the numbers · Add and divide by five for the mean · Find the middle, most frequent and end-to-end difference.

Common input mistake

The median is less affected by very large or very small outliers than the mean.

Mean = ΣValues ÷ Count; Median = middle sorted value; Mode = most frequent value; Range = Maximum − Minimum

A data set may have more than one mode or no mode when every value appears equally often.

Keep in mind: Clean the data and confirm whether repeated values should remain before interpreting the summary.
