18
What is the expression for finding the upper limit?
Q3 + (1.5 x IQR)
What is is called when you find the distance between Q3 and Q1
IQR
Construct a dot plot with the following data:

What is the difference between mean and mean absolute deviation (MAD)?
The mean is the average of all of the data values. The MAD is the average of all of the distances from the mean.
Name two differences between dot plots and histograms
1. dot plots use dots to show the data while histograms use bars to show the data
2. dot plots show each data point separately while histograms chunk data together to create ranges
