Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.
grin007 [14]

Answer:

<u>D. </u>

<u>Mean: 24.8</u>

<u>Median: 26</u>

<u>Mode: 26</u>

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

<u>Mean: 24.8</u>

<u>Median: 26</u>

<u>Mode: 26</u>

<u></u>
