CC Tessa is investigating the number of strawberries in a pound package. She has six packages of strawberries and count the number of strawberries in each package results follow
10,12,14,15,16,17
What is the main absolute deviation of her data?
To calculate the mean absolute deviation, we first need to calculate the mean of the data set:
(10 + 12 + 14 + 15 + 16 + 17) / 6 = 84 / 6 = 14
Next, we calculate the absolute deviation of each data point from the mean:
|10 - 14| = 4
|12 - 14| = 2
|14 - 14| = 0
|15 - 14| = 1
|16 - 14| = 2
|17 - 14| = 3
Now, we find the mean of these absolute deviations:
(4 + 2 + 0 + 1 + 2 + 3) / 6 = 12 / 6 = 2
So, the main absolute deviation of Tessa's data set is 2.
