These dot plots have the same variability:
True
Which would be greater: the mean or the median?
The mean would be greater because it is being pulled up by the data values on the right.
Make a boxplot for the data. Label all your marks with their value (Median ____ )

Median: 12.5
Q3: 15
Max: 17
The median would be less than the mean.
False.
