Mean, Median, and Mode PRACTICE

Lesson Plan - Get It!

Audio:

To get started, let's do a quick review of mean, median, and mode.

What better way than with an example?

Find the mean, median, and mode for this set of data:

7, 8, 10, 12, 14, 6, 8, 9, 11, 10.

If you need a quick reminder of these terms, here it is:

Mean

• the average — Add all the numbers in a set and divide by the total numbers in the set.

Median

• Find the middle number when the numbers are listed from least to greatest. (HINT: If there are two middle numbers, add them together and divide by 2.)

Mode

• the number that appears the most in the set

And why not throw in an extra?

Range

• the highest number in the set minus the smallest number in the set

Okay, your turn!

Figure out the mean, median, and mode of the data set above on a piece of paper.

Then, come back and check your work. No peeking before you have tried!

• How did you do?
• Did you get the answers correct?

If not, please try it again looking at the step-by-step explanations above.

Once you feel ready, go to the Got It? section for some more practice.
