New feature analyzes test results

dataMetrics has created the Correlation Report to help TestWiz customers view the relationship between two assessments.

The new TestWiz report allows educators to select any two assessments given to the same students and calculate the correlation between the two – in the form of a Pearson Product Moment Correlation Coefficient (-1 to +1). The report also provides a visual representation of the correlation through a scatter plot of the test scores.

The report can give educators insight as to whether results on a locally developed test can be used to predict performance on a high-stakes test.
