FIG. 8.

Variability in behavioral data. Coefficients of variation are shown for 18 behavioral measures for each of the six groups. There was no effect of sex or injury on the mean coefficients of variation (data not shown), and the distribution of variability was also unaffected by sex or injury as assessed by Levene's test of equality of error variance. Open and closed symbols represent males and females, respectively, and circles, triangles, and squares represent sham, mild and severe injury, respectively. MWM, Morris water maze; CCI, controlled cortical impact.
