Words and music (1.5, 1.6) For a project in their statistics class, Alex and Tempe studied the impact of different types of background music on students’ ability to remember words from a list they were allowed to study for 5 min.
Here is a histogram that displays the data on how many words one group of students who listened to Beethoven’s Fifth Symphony were able to remember.
What is the shape of the histogram? Use this to decide the relationship between the mean and the median, ex. which one is bigger?

a) Find 120 on the x axis, draw a line up to the graph, then draw a line to the left to find the cumulative relative frequency. This is the percentile.
b) find the percentile for the median, Q1 and Q3 on the y axis, then draw a line over to the graph, then draw a line down to the x axis to find the data value for the median, Q1 and Q3. Use Q3 & Q1 to find the IQR.
