Hey Diddle Diddle the Median’s in the Middle by Kay McCullough D.RE.04.02 Order a given set of data, find the median, and specify the range of values.

Median Mean Mode Range Hey diddle diddle, the median’s the middle, You add then divide for the mean. The mode is the one that you see the most, And the range is the difference between.

Statisticians figure the range, median, mode, and mean of data collected.

This is just a different way of looking at numbers.

The data collected is the number of whales.

Step one- Put the data in order from least to greatest. / / / / / / / / / / 31 27 36 23 23 25 15 19 19 20 Step one- Put the data in order from least to greatest.
