Understanding Quartiles, Percentiles, and Deciles

This video tutorial explains how to calculate quartiles, desiles, and percentiles using Excel. It covers the basic concepts of quartiles, including the zero, first, second, and third quartiles, and their equivalence to percentiles. The tutorial also demonstrates how to use Excel functions to find these values and explains the relationship between desiles and percentiles. By the end of the video, viewers will understand how to calculate these statistical measures using Excel.
