To find the median, place the given numbers in order of their value and find the middle number.
Here we have:
57, 61, 58, 54, 68, 51, 49, 64, 50, 48, 65, 52, 56, 46, 47, 55, 42, 60, 62, 43, 69, and 70.
Arranging them in order from least to greatest, we have:
42, 43, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 61, 62, 64, 65, 68, 69, and 70.
There are 22 numbers total; the median will be the mean of the middle two numbers, which are 55 and 56.
To find the mean, add the numbers together and divide the sum by 2.
55 + 56 = 111
111 / 2 = 55.5
