Document Summary
One-way anova: does not look at the mean directly, but at the variances, based on the raio of between-group variance and within-group variance, example. Corrected model = overall model emphasize corrected model : post-hoc comparisons. Larger the value = more variance of the dv that is explained by the iv: efect size. Conclusion: age of onset of criminal acivity accounts for 55% of the variance in the length of someone"s criminal career. Are there signiicant diferences between the groups of the iv in relaion to the. What is the interacion efect of iv1 and iv2 on the group means: fundamentally similar to a one-way anova, key advantages to the two-way anova. Allows for the examinaion of interacion efects: interacion efects. The efect of one iv on the dependent variable difers depending on the presence of another iv. Efect of one iv is dependent on another iv.
