Subclaims¶

q2 i? ANCOVA on pretest scores yielded F = 0.02, not significant at 0.05, indicating the three groups were statistically equivalent in drawing skills prior to treatment. → Abass et al. 2014

Bada Tayo Abass, Bello Isyakka, Ijisakin Yemi Olaolu & Fajuyigbe Michael Olusegun. (2014). Effects of Two and Three-Dimensional Visual Objects on the Acquisition of Drawing Skills among JSS1 Students in Osun State, Nigeria. World Journal of Education, 4(1). https://doi.org/10.5430/wje.v4n1p62

q2 · i? · causal · r2

ANCOVA of pretest VOAT scores for the three groups (n = 40 each): TDVO mean 9.2 (SD 2.2284), TWDVO mean 8.9, control mean 8.6. The article reports "an F-ratio of 0.02", not significant; no effect size is printed.

"When these values were subjected to Analys is of co-variance (ANCOVA) as shown in Table 1.1 an F-ratio of 0.02 was obtained. This value is not significant at 0.05 level. This implies that prior to the treatment programme, the subjects in the three groups were not statistically different in their drawing skills."
