Find the median, mode, and range for

54, 55, 60,66,69, 72, 73, 74, 75, 75, 83, 82, 88, 89, 95, 96

To find the median we put the numbers from least to greatest, and cross out the smallest number with the biggest number, until we can't any longer.

54/96, 55/95, 60/89, 66/88, 69/83, 72/82, 73/75, 74/75.

Since we ended with 74 and 75, pick the decimal number that's in between those two numbers, 74.5.

74.5 is your median.

The mode is the number that's most frequent.

There are two 75's, so 75 is your mode.

Range is the difference of the highest number and the lowest number.

96-54=42.

The range is 42.
