In september, seattle's daily high temperature has a mean of 70 °f and a standard deviation of 7 °f. What are the mean, standard
Anna [14]
Mean= is the summation of the maximum temperatures ÷ the numbers of times the temperatures where recorded

standard deviation= is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.

A low standard deviation means that most of the numbers are very close to the average.

A high standard deviation means that the numbers are spread out.

Variance= is a way to measure how far a set of numbers is spread out.

A variance of zero indicates that all of the data values are identical. All non-zero variances are positive.

A small variance indicates that the data points tend to be very close to the mean, and to each other.

A high variance indicates that the data points are very spread out from the mean, and from one another.
