Subclaims¶

q2 i2 In an underpowered random assignment study (34 Fusion Reading, 35 Second Chance Reading students) analyzed with HLM, a significant treatment-by-occasion interaction was found on the GRADE Composite comprehension standard score, F(2, 88) = 3.53, p = .03, with Hedges's d of 0.70 (raw) and 0.66 (standard scores). → Hock 2017

q2 · i2 · causal · r2

Underpowered random assignment study in which 34 students received Fusion Reading and 35 received Second Chance Reading, analyzed via hierarchical linear modeling in SAS PROC MIXED. The treatment-by-measurement-occasion interaction on the GRADE Composite standard score was significant, "F (2, 88) = 3.53, p = .03"; the article reports Hedges's d of 0.70 and 0.66 for raw and standard scores.

"A significant interaction was found between treatment and measurement occasion for the standard score on the GRADE Composite comprehension score, F (2, 88) = 3.53, p = .03. The pre to post gain for the experimental group was statistically significant, F (2, 88) = 4.59, p = .01."
