Calculating the Mean Deviation about the Mean:
To calculate the mean deviation about the mean, we first need to find the mean of the given data set.
Finding the Mean:
First, add up all the numbers in the data set:
6 + 7 + 10 + 12 + 13 + 4 + 8 + 12 = 72
Next, divide the sum by the total number of values in the data set:
72 / 8 = 9
So, the mean of the data set is 9.
Calculating the Mean Deviation:
Next, we find the deviation of each number from the mean:
|6-9| = 3
|7-9| = 2
|10-9| = 1
|12-9| = 3
|13-9| = 4
|4-9| = 5
|8-9| = 1
|12-9| = 3
Now, we calculate the mean deviation by finding the average of these deviations:
(3 + 2 + 1 + 3 + 4 + 5 + 1 + 3) / 8 = 22 / 8 = 2.75
Therefore, the correct answer is option D) 2.75.
