To find the mean absolute deviation, we first find the mean of the data set:
(204 + 211 + 216 + 300 + 426 + 567 + 680) / 7 = 311
Next, we find the absolute deviation of each data point from the mean:
|204 - 311| = 107
|211 - 311| = 100
|216 - 311| = 95
|300 - 311| = 11
|426 - 311| = 115
|567 - 311| = 256
|680 - 311| = 369
Now, we find the mean of these absolute deviations:
(107 + 100 + 95 + 11 + 115 + 256 + 369) / 7 = 155.4
Rounded to the nearest 10th, the main absolute deviation of the data set is 155.4.
