From any Powerful Predictor Chart, click the 'Build Paired Predictors' button located above the chart to see the effects of two Powerful Predictors in combination. The original Powerful Predictor will be listed as the x-axis variable. Use the dropdown menus to select a Powerful Predictor to populate the y-axis.
The visualizations on the left and right show the effect of each selected variable on persistence rates for the filtered student group.
The chart on the left shows the historical ratio of persisting students to non-persisting students, the persistence rate for that group, and the number of students in each quadrant who persisted and did not persist (based on known historical outcomes). Start by reviewing the center circle, which includes persistence information for the full student group. This information is based on historical student data, so this persistence information will not match the Persistence Prediction on the Overview page. Easily identify quadrants where the ratio of persisters to non-persisters is higher than average by observing the text color. Green indicates a higher than average persistence ratio and red indicates a lower than average persistence ratio.
The right distribution shows a much more granular breakdown of student behaviors. The heat map shows the distribution of persisting and non-persisting students over the continuum of values for each Powerful Predictor. The black lines show the median values for each Powerful Predictor among the student group. Red indicates a higher percentage of non-persistence than persistence among the student group and green indicates the opposite. Gray indicates that there is no historical data for that combination of values for the chosen Powerful Predictors. Hover over any point in the distribution to see the historical ratio of persisters to non-persisters at that combination of values. Lighter shades of green and red correspond to smaller subsets of students at that combination of values.
Both visualizations are organized into quadrants. The layout of the quadrants aligns with the layout of this table:
Students with x-values below the median and y-values above the median
Students with values above the median for both variables
Students with values below the median for both variables
Students with x-values above the median and y-values below the median
See a list of the currently enrolled students exhibiting any combination of the two behaviors by clicking Active Students in any quadrant of the ratio chart.
