To compare and contrast standard deviation and absolute mean deviation

Answer to Problem 27HP
Comparison-Both standard deviation and absolute mean deviation measure the dispersion of the data and is computed to obtain the distance of the data to its mean.
Contrast- Thestandard deviation calculate the square of the difference whereas mean absolute deviation only look at the absolute difference.
Explanation of Solution
Given information:
The comparison between the standard deviation and absolute mean deviation is,
Both standard deviation and absolute mean deviation are calculated statistical values that show how each data value deviated from mean of the data set and also both measure the dispersion of the data by computing the distance of the data to its mean.
The difference between the standard deviation and absolute mean deviation is,
The mean absolute deviation is calculated by taking the mean of the absolute values of the differences between each number and mean of the data set while the standard deviation is calculated when the square of each difference is taken and then the square root of the mean of the square is taken.
Therefore, both standard deviation and absolute mean deviation measure the dispersion of the data and is computed to obtain the distance of the data to its mean. And standard deviation calculate the square of the difference whereas mean absolute deviation only look at the absolute difference.
