Which display would you prefer to use to determine the median?

• box plot

• line plot

• stem and leaf

Answer explanation

The box plot displays the median without having to do any calculations.

The appropriate measure of spread for a data set that is skewed is...

• range

• standard deviation

• IQR

Answer explanation

The IQR gives a consistent measure of variability for skewed as well as normal distributions.

The _________ can be used to determine the range.

• Box plot

• Line plot

• Histogram

Answer explanation

You need to smallest and largest value to be able to determine the range.

The larger the standard deviation, the more the spread out the data is.

• TRUE

• FALSE

The best measure of variability for bell-shaped numerical data is

• IQR

• Range

• Standard Deviation

Answer explanation

The standard deviation of a data set is the variation of each value to the mean.
