Compute the range, variance and standard deviation for these data.

Round your answers to the nearest integer, where appropriate.

Explanation / Answer

Range of the data means maximum minus minimum. Here maximum salary is 3800 and minimum is 418 so range is 3382

To calculate the variance follow these steps: Work out the Mean (the simpleaverage of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average. So the variance is 1562043.5

Standard deviation is square root of variance so ad is 1249.817
