Research Brief: Forecasting AIMS from AZCCRS Tests
|
Method- Predictive Validity Analyses
- For the statewide test, each student received a scale score and also was classified based on whether or not they passed the statewide test.
- For each Galileo assessment, ATI performed an IRT analysis to produce a Developmental Level (DL) score for each student.
- For predictive validity analyses, correlation statistics were computed to evaluate the strength of the relationship between student DL scores on a Galileo assessment and student scale scores on the statewide assessment.
- The correlation statistic ranges from -1 to +1 with the sign and magnitude of the correlation indicating the direction and strength of the relationship, respectively.
- A positive correlation indicates that high scores on one measure are associated with high scores on the other. A negative correlation indicates that high scores on one measure are associated with low scores on the other. Typically only positive values are observed in this context.
- A correlation between 0.7 and 0.9 indicates a high correlation between the two measures while a correlation between 0.5 and 0.7 indicates a moderate relationship.
