ANALYSIS OF FAST SEQUENCE SPEED

NARRATIVE RESULTS

Levene's test was significant (F = 9.581, p < .01), therefore homogeneity of variances between groups could not be assumed. Independent samples T-test (variances not assumed)
showed that Aged mice produced significantly faster action sequences (t(7.417) = -4.201, p < 0.01).
