MMM #10 MEAN MODE MEDIAN RANGE

Front

What is the mean?

Back

The mean is the average of a set of numbers, found by adding all the numbers together and dividing by how many numbers there are.

Front

How do you find the mean of these numbers: 5, 11, 2, 12, 4, 2?

Back

Add the numbers: 5 + 11 + 2 + 12 + 4 + 2 = 36. Then divide by 6 (the number of values): 36 ÷ 6 = 6.

Front

What is the range?

Back

The range is the difference between the greatest and least numbers in a set.

Front

How do you find the range of these numbers: 5, 11, 2, 12, 4, 2?

Back

Subtract the smallest number (2) from the largest number (12): 12 - 2 = 10.

Front

What is the mode?

Back

The mode is the number that appears the most in a set of numbers.

Front

How do you find the mode of these numbers: 4, 3, 6, 4, 3, 6, 6, 3, 2, 1, 3?

Back

First, arrange the numbers: 2, 2, 2, 2, 4, 5, 5, 6, 6, 6. The middle numbers are 4 and 5, so the median is (4 + 5) ÷ 2 = 4.5.

Front
