Document Summary

While a one-way anova has only one independent variable (iv), factorial anova. Factorial anova requires at least 2: ivs called factors , only one dependent variable (dv) Is there a time x gender interaction: degree of freedom. Factor of time (2 groups) weekday vs weekend. Df between = k -1 = 2-1= 1 df between = k-1= 2-1= 1: here within called error , df error = ntotal k= 24 -4 = 20. F= (cid:3279)(cid:3281)(cid:3280)= (cid:2872)(cid:2873).
