A rectangle has a width if 10 inches and an area of 5 square inches. What is the length of the rectangle?
October 8, 2007

6th Grade Statistics
The student is correct because the median is used to find the middle numeric value of a data set, the mean balances out the data so all numbers in a data set are the same. This means that the mean and median can only be used for a numeric data, so this student is correct.
