Statistics

A Statistics course is required at the college level for completion of requirements in a surprisingly large number of fields of study that seem to vary widely. Topics in Statistics include the study of various “averages” and standard deviation and extend into probability, various sampling distributions, estimating using confidence intervals, and hypothesis testing. Special emphasis is given to real world applications. The graphing calculator is used extensively.
