a. This analysis shows the effects of different teaching styles on reading scores by using an analysis of the variation between groups and within groups. This ANOVA analysis then allows us to see how close our data is to the null. b. Null: μ Basal = μ DRTA = μ Strat c. Effect of Teaching Methods on Reading Score 0 10 20 30 40 50 60 Basal DRTA Strat Teaching Method The chart shows the effect of teaching style on reading score. The averages within each group were plotted with error bars created from the standard error within each group. The averages for each group were calculated to be Basal = 41.045, DRTA = 46.727, and Strat = 44.273. This shows that the DRTA teaching method results in the highest reading scores while the Basal teaching style resulted in the lower reading

Unformatted text preview: scores. The standard errors for the groups were 1.202, 1.575, and 1.229 respectively. Therefore the smallest error bar was seen in the Basal teaching method while the largest error bar was seen for the DRTA teaching method. d. and e.
