To find the mean absolute deviation, first find the mean of the data points:
Mean = (10 + 12 + 14 + 15 + 16 + 17) / 6
Mean = 84 / 6
Mean = 14
Next, 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, find the mean of these absolute deviations:
Mean absolute deviation = (4 + 2 + 0 + 1 + 2 + 3) / 6
Mean absolute deviation = 12 / 6
Mean absolute deviation = 2
Therefore, the mean absolute deviation of Tessa's data is 2.
Tessa is investigating the number of strawberries in a 1-pound package. She has 6 packages of strawberries and counts the number of strawberries in each package. Her results follow.
