Assumptions
Shapiro-Wilk suggests group "KINSELLA" is not normally distributed (p=7.53e-06).
Shapiro-Wilk suggests group "MATTHEIS" is not normally distributed (p=1.706e-05).
- Shapiro-Wilk, group KINSELLA: W=0.9513, p=7.53e-06 — non-normal
- Shapiro-Wilk, group MATTHEIS: W=0.9623, p=1.706e-05 — non-normal
- Levene's test (equal variances): p=0.986
