First, let's find the mean of these data points:
Mean = (98 + 92 + 96 + 97 + 97) / 5 = 96
Next, we need to find the deviation of each data point from the mean:
|98 - 96| = 2
|92 - 96| = 4
|96 - 96| = 0
|97 - 96| = 1
|97 - 96| = 1
Now we need to find the mean of these deviations:
Mean of Deviations = (2 + 4 + 0 + 1 + 1) / 5 = 0.8
Therefore, the mean absolute deviation is 0.8.
The top five test scores in Mr. Rhodes class were: 98, 92, 96, 97, and 97. What is the mean absolute deviation?
