According to the data set, the mean is given by:
[tex]\mu=\frac{1}{n}\sum_{i=1}^nx_i[/tex]Where n is the total number of values and Xi is the value with index i. According to this calculation, the mean is 7.68.
Since the least value is 2 and the largest is 25, the range is 23.
The median if the value with separates the lower half of the data set from the upper half. In this case, the median is.
The mode is the most common value in the data set. Then the mode is 3.
Finally, the mean absolute deviation is the average distance of a given value from the mean, Which is given by:
[tex]\frac{1}{n}\sum_{i\mathop{=}1}^n|(x_i-\mu)[/tex]Then, the MAD is 4.22
