• median

The shape of the distributions is __________________________________________.

• Skewed left

• Skewed right

Which value is smaller, the mean or the median?

• mean = 2.14 median = 2.5

• mean = 2.14 median = 2

• mean = 2 median = 2.14

• The median is smaller

• The mean is smaller

Which measure of center is more appropriate, the mean or the median? Why?

• Mean because this is a skewed data set.
