q2 i? Treatment and control groups showed no difference on the posttest searching exercise activity (t(106) = -0.04, p = .96). → Goetz 2015

q2 · i? · causal · r2

Quasi-experimental (nonequivalent control group) study of 138 M.Ed. graduate students in five 90-minute library sessions; independent t tests compared groups on the rubric-coded performance activity. The article reports "no difference, t (106) = -0.04, p = .96"; means were 2.29 (treatment) vs 2.30 (control).

"Posttest searching exercise activity responses showed no difference, t (106) = -0.04, p = .96 (see Table 1). Thus, the hypothesis that the treatment group would demonstrate better performance on a searching exercise was partially supported."
