[a] For digits, the one-way ANOVA for the effect of grade produced a significant F (5,1202) value of 62.54, p < .001; the F (1,1202) for the linear trend was 97.91, p < .001 and for the quadratic trend, F (1,1202) = 24.41, p < .001. Student-Newman Keuls revealed that 2 = 3 = 1<6<4 = 5. For problems, ANOVA indicated a significant F (5,1202) value of 39.65, p < .001; the F (1,1202) for the linear trend was 24.51, p < .001 and for the quadratic trend, 23.04, p < .001. Student-Newman-Keuls revealed that 6 = 2<5 = 3 = 4<1.
