For the data set distribution of Salaries of the employees
1. Arrange in an array (ascending order)
2. Evaluate the mean, the median, the mode, the skew, the average deviation the standard deviation and the interquartile range.
3. Group, on a new worksheet, the data in classes then build a histogram and a polygon.
4. Repeat the calculations for Mean, the Median, the Mode and the Interquartile range for grouped data

N.B

The average deviation of a set of scores is calculated by computing the mean and then the specific distance between each score and that mean without regard to whether the score is above or below the mean. It is also called an average absolute deviation. Below mentioned is the formula to calculate the average deviation.
