Test Analysis

Use Test Analysis to analyze one or two tests. It analyzes both test items and test scores and is especially useful for pretest/posttest or experimental/control group comparisons.


Correlation Analysis

Use Correlation Analysis to analyze columns of data such as exam scores, attendance, homework scores, etc. in order to determine correlation coefficients and significance.


Factor Analysis

Use Factor Analysis to determine factors on a test. Factor analysis helps you identify questions that are statistically related, but does not in general tell you the meaning or explanation of the factors. You can read more about factor analysis in the documentation.
