The Table below is a data set that lists how many pairs of shoes are owned by some of your classmates.
Pani-rosa [81]

Answer:

7.5

Step-by-step explanation:

<u>To find the median, first order the numbers from least to greatest:</u>

2, 4, 5, 7, 8, 8, 10, 12

<u>Then, find the middle number (number in the middle):</u>

There are 2 middle numbers. 7 and 8.

Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.

<u>To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;</u>

7 + 8 = 15

15 / 2 = 7.5

Have a nice day!
