Question

Mean deviation can be computed from​

Answer 1

Step-by-step explanation:

The mean deviation is calculated either from mean or median, but only median is preferred because when the signs are ignored, the sum of deviation of the sets taken from median is minimum.

Answer 2

Answer:

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

Step-by-step explanation:

the deviation is from the median, we will divide it by median and if the deviation is from mode, we will divide it by mode. Let us see the formulas to calculate the mean deviation from the mean, median, and mode.
