Question
What is the sum of the absolute deviations in the following dataset: 63, 25, 74, 52, 63, 12, 46? The mean of the dataset is 47.9. Round to the nearest tenth.(1 point)

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the absolute deviation for each data point, we subtract the mean (47.9) from each data point and take the absolute value.

|63 - 47.9| = 15.1
|25 - 47.9| = 22.9
|74 - 47.9| = 26.1
|52 - 47.9| = 4.1
|63 - 47.9| = 15.1
|12 - 47.9| = 35.9
|46 - 47.9| = 1.9

The sum of all these absolute deviations is 15.1 + 22.9 + 26.1 + 4.1 + 15.1 + 35.9 + 1.9 = 121.1

Therefore, the sum of the absolute deviations in the dataset is 121.1.
