• uniform

• skewed to the right

• skewed to the left

Because this distribution is ____________ to the ___________, we would use the ______________ for the center and the _____________ for the spread of the data.

• symmetric, middle, median, IQR

• skewed, left, median, IQR

• skewed, left, mean, IQR

• skewed, right, median, standard deviation

The IQR is the

• max - min

• Interquartile Range

• measure of spread that pairs with the mean

• Q₃ - Q₁
