QNT 275 Week 1 participation The Wisconsin Water Table

What is the Variance, Standard Deviation and Mean of the data below?

Wisconsin Water Table

This is a great example of a real table that you can find in academic journals or government periodicals.

All you have to do is find the mean, standard deviation and variance. We are going to be using this very same table for Z-score as well:

The following table presents a data file that lists the peak discharge from a hydroelectric project in

Wisconsin for the years 1957 to 1968. The variable peak discharge has an interval level of measurement.
