Front

How do you find the mean of the numbers 4, 8, 6, 10?

Back

Add the numbers: 4 + 8 + 6 + 10 = 28. Then divide by the count of numbers: 28 ÷ 4 = 7. The mean is 7.

Front

If the numbers are 5, 3, 9, 1, what is the median?

Back

First, sort the numbers: 1, 3, 5, 9. The median is the average of the two middle numbers (3 and 5): (3 + 5) ÷ 2 = 4.

Front

What is the mode of the numbers 2, 4, 4, 6, 7?

Back

The data set has no mode, as no number appears more than once.
