Assessment Analysis



by Oliver Hinds and Aaron Titus







Assessment Analysis was written to help teachers analyze tests and 

other classroom data without using expensive statistical analysis software.

It is useful for analyzing one or two tests (such as a pretest and posttest

or the same test given two experimental and control groups), determining 

correlations between sets of data, and determining factors on a test using

factor analysis.
