This video tutorial covers measures of spread, focusing on interquartile range (IQR) and range. It explains how to calculate quartiles, which divide data into four equal parts, and demonstrates finding quartiles in a data set. The tutorial also details calculating the IQR by subtracting the first quartile from the third quartile and finding the range by subtracting the minimum value from the maximum value. Additionally, it introduces the five number summary, which includes the minimum, maximum, and three quartiles, to describe data distribution.
