Answer:

21.5

Step-by-step explanation:

Median = Middle

Arrange the numbers:

18, 18, 18, 20, 21, 22, 23, 23, 24, 24

There is no exact middle, so

21 + 22 = 43

43 ÷ 2 = 21.5
Put each number from least to greatest.
In that case it would be:
18,18,18,20,21,22,23,23,24,24
Start scratching off 1 number of each side until there is a center
In this case:
21 and 22 are the center numbers so you would add both and divide by 2.

21+22 = 43 / 2 = 21.5
