ANALYSIS OF OVERALL MAGAZINE CHECK RATE

Test: Two-way mixed ANOVA
Factors: within-subject: Day; between-subjects: Group.

NARRATIVE RESULTS
The results show that the overall magazine check rate significantly varied as sessions progressed in both groups: F(2.816, 39.428) = 8.68, p < 0.001.  There was no significant 
Day*Group interaction F(2.816, 39.428) = 0.380, p = 0.755), indicating that both groups similarly increased their magazine check rates. Between-subjects effects supported this
conclusion, as it revealed no significant differences between groups (F(1, 14) = 0.933, p = 0.351).
