I wants to analyze data of 2 factor experiment , while doing ANOVA on SPSS it gives me the result like this
Levene's Test of Equality of Error Variances(a)
Dependent Variable:Response
F df1 df2 Sig.
1.457 107 216 .011
Wherase, If the test is statistically significant (e.g., p
It says the test is for equality of variances. What the p value means is that the variances are equal at this level. Why do you think the error distribution is not normal?You need something like a Kolmogorov-Smirnov test to look at normality. BTW saying you have a two factor experiment doesn't tell us much. For all of this See below. If you do need nonparametric statistics, see the book below. Best wishes.
