13,14,29,26,41,53,60,7,89,14

Based on the numbers above what is the variance and the standard deviation of the data set.

I think 616.2 is the variance

I think 24.83 is the standard deviation

Am I correct????

Go on :

wolframalpha dot com

When page be open in rectangle type :

variance {13,14,29,26,41,53,60,7,89,14}

and click option =

Then in rectangle type :

standard deviation {13,14,29,26,41,53,60,7,89,14}

The variance = 685.156 approx. 685.2

The standard deviation = 26.1755 approx. 26.18
