How to fill out measures of variation

1. To fill out measures of variation, follow these steps:
2. Collect the data set for which you want to calculate the measures of variation.
3. Calculate the mean of the data set by summing all the values and dividing by the number of values.
4. Calculate the deviation of each value from the mean by subtracting the mean from each value.
5. Square each deviation obtained in step 3 to eliminate negative signs.
6. Calculate the sum of all squared deviations.
7. Divide the sum of squared deviations by the total number of values to get the variance.
8. Take the square root of the variance to get the standard deviation.
9. Calculate other measures of variation, such as range, interquartile range, and coefficient of variation if needed.
