Subclaims¶

q3 i? The Absolute Accuracy Index was a significant predictor in the Word Reading and Composite Score regression models (14% and 13% of variance), with lower scores indicating better calibration associated with higher achievement; it did not significantly predict Numerical Operations or Spelling. → Freeman 2017

Evidence¶

Freeman 2017¶

q3 · i? · associational · r2

Regression models with the Absolute Accuracy Index as predictor; significant for Word Reading and Composite Score with negative regression weights, whereas only age significantly predicted Numerical Operations scores.

"The models in which the Absolute Accuracy Index was included as a predictor explained a significant amount of variance in Word Reading, Numerical Operations, and Composite scores (14%, 14%, and 13%, respectively). The Absolute Accuracy Index was a significant predictor in the Word Reading and Composite models"
