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 her results follow { 10, 12, 14, 15, 16, 17}

Question

What is the main absolute deviation in her data?
The mean absolute deviation is_____

Answer 1

To find the mean absolute deviation, we first need to find the mean of the data.

Mean = (10 + 12 + 14 + 15 + 16 + 17) / 6 = 84 / 6 = 14

Next, we find 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 calculate the mean absolute deviation:

Mean absolute deviation = (4 + 2 + 0 + 1 + 2 + 3) / 6 = 12 / 6 = 2

Therefore, the mean absolute deviation is 2.
