First, we need to find the mean of the dataset:
mean = (125 + 198 + 209 + 213 + 101 + 178) / 6
mean = 151.33
Next, we need to find the absolute deviation of each value from the mean:
|125 - 151.33| = 26.33
|198 - 151.33| = 46.67
|209 - 151.33| = 57.67
|213 - 151.33| = 61.67
|101 - 151.33| = 50.33
|178 - 151.33| = 26.67
Then, we find the mean of these absolute deviations:
mean absolute deviation = (26.33 + 46.67 + 57.67 + 61.67 + 50.33 + 26.67) / 6
mean absolute deviation = 42.11
Rounded to the nearest tenth, the mean absolute deviation of the dataset is 42.1.
To find the mean absolute deviation (MAD) of a dataset, follow these steps:
1. Find the mean (average) of the dataset.
125 + 198 + 209 + 213 + 101 + 178 = 1024
1024 ÷ 6 = 170.7 (rounded to the nearest tenth)
2. Find the absolute value of the difference between each data point and the mean.
125 - 170.7 = 45.7
198 - 170.7 = 27.3
209 - 170.7 = 38.3
213 - 170.7 = 42.3
101 - 170.7 = 69.7
178 - 170.7 = 7.3
3. Find the mean of the absolute values calculated above.
(45.7 + 27.3 + 38.3 + 42.3 + 69.7 + 7.3) ÷ 6 = 39.4 (rounded to the nearest tenth)
Therefore, the mean absolute deviation (MAD) of the dataset is approximately 39.4.
