Word recognition (WRAT-R) and reading comprehension (GMRT) scores were used as criterion measures. All scores were residuals with age partialled out. The results of the multiple regression analysis for the overall sample showed that: 18% (Adjusted R2) of the variance in word recognition scores...
Welcome to the course Data analysis: Multiple regression analysis using R. This course introduces the concept of regression using Sir Francis Galto n’s parent- child height data and then extends the concept to multiple regression using real examples. The course has an applied focus and makes mi...
Analysis of variance(ANOVA) is a statistical procedure that provides information on the explanatory power of a regression. The result of the ANOVA procedure are presented in an ANOVA table, which accompanies with the output of a multiple regression program. An example of a generic ANOVA table is...
