ANALYSIS OF EFFICIENCY

NARRATIVE RESULTS

Levene's test was not significant (F = 0.386, p = 0.546), therefore homogeneity of variances between groups could be assumed. Independent samples T-test
showed that CRE mice obtained significantly more food outcomes that WT mice (t(12) = -2.400, p = 0.033).
