Statistical Analyses of Variability


This RWLO can be implemented immediately after students have gained familiarity with the concept of standard deviation.

The instructor may quickly access the website, if the facilities are present, when making the assignment. Discussion of statistics gathered by various government agencies provides an excellent framework for the broad uses of statistical information. If computers or the website are not available, copies of the CPI information may be copied and given to students.

If Excel is not an option, the calculations for the mean and standard deviation may be done with calculators.
