Discrete Random Variables – Mean

Question 8 • NC-Math 4

A popular streaming service surveyed all of the students at a school about the number of TV shows they streamed last Friday night, then recorded the results. Let M = the number of TV shows streamed last Friday night. Calculate the median of M. Use the histogram to corroborate your choice of the distribution’s shape. Since the shape of the distribution for number of TV shows streamed is , we expect the median to be the mean number of TV shows streamed. This is confirmed when we calculate the median to be , compared to the mean of 2.187 TV shows streamed. The shape of the histogram supports the relationship of the mean and the median because the mean is .
