Question

Approximately what percent of the values in a distribution lie between the 25th percentile and the 75th percentile?

A. 75%.
B. 25%.
C. 50%.
D. None of the above.

Answer 1

Answer: 75% of your data are below the 75th percentile. 25% of your data are below the 25th percentile. Therefore, 50% (=75%-25%) of your data are between the two, i.e., between the 25th and the 75th percentile.
