ANALYSIS OF FAST SEQUENCE IPIs

NARRATIVE RESULTS

Levene's test was not significant (F = 2.594, p = 0.13), therefore homogeneity of variances between groups could be assumed. Independent samples T-test
showed that Aged mice produced significantly shorter IPIs in their action sequences (t(14) = 2.724, p < 0.05).
