Mean, median, mode, and range

Find the mean, median, mode, and range of a group of numbers

This math skill teaches how to calculate the mean, median, mode, and range of a set of numbers. It explains the processes of finding average, middle value, most frequent value, and difference between highest and lowest values in a dataset.

Teaching Transcript

🎙️

Let's find the mean, median, mode, and range of the number of shapes in these groups

The mean, or average, is the number in each group if you divide them up evenly

We have 12 in total and 4 groups to divide them amongst

So our mean is 3

The median is the middle number if the numbers are arranged in order

We have 1, 2, 2, and 7. Since there's no middle number we go half way in between the two closest to the middle.

They are both 2, so our median is 2.

The mode is the number that occurs most frequently

We have two with 2

So our mode is 2

And the range is the difference between top and bottom

That's 1 and 7 in our case

So our range is 7 minus 1, which is 6.
