Teresa counted the number of tomatoes in 9 baskets at a vegetable stand. The list shows the data. 11, 12, 8, 12, 8, 8, 11, 11, 9

What is the difference between the mean and median of the data?

1 answer

To find the mean, we need to sum up all the numbers in the data set and then divide by the total number of baskets.

Sum of the numbers: 11 + 12 + 8 + 12 + 8 + 8 + 11 + 11 + 9 = 90
Mean: 90 / 9 = 10

To find the median, we need to arrange the numbers in numerical order and find the middle value.

Arranging the numbers in ascending order: 8, 8, 8, 9, 11, 11, 11, 12, 12
Median: 11

The difference between the mean and median is 11 - 10 = 1.

Therefore, the difference between the mean and median of the data is 1.
