Find the variance for a given data. Rpund your answer to one more decimal place then the original data.

Compute the variance. Jeanne is currently taking college zoology. The instructor often gives quizzes. On the past five quizzes, Jeanne got the following score.

17 10 7 14 3

This involves finding the mean, subtracting each score from the mean, squaring each of those scores, adding them up and dividing that sum by the number of scores.

To get the standard deviation (SD), find the square root of the variance.

I hope this helps. Thanks for asking.
