One-Way (Single Factor) ANOVA. • When comparing more than two means for samples that are independent (not correlated). • Only one Independent and one Dependent variables are involved. • Between-subjects indicates independent variables while within subjects indicate correlated samples.
Two-Way Anova with a Balanced Design and the Classic Experimental. Approach. We can use Analysis of Variance techniques for these and more complicated problems. These techniques can get fairly involved and employ several different options, each of which has various strengths and weaknesses. If this were a
TWO-WAY ANOVA. Two-way (or multi-way) ANOVA is an appropriate analysis method for a study with a quantitative outcome and two (or more) categorical explanatory variables. The usual assumptions of Normality, equal variance, and independent errors apply. The structural model for two-way ANOVA with interaction is

Continuous (scale/interval/ratio) and 2 independent categorical variables (factors). Common Applications: Comparing means of a single variable at
28 May 2014 Replication in two-way ANOVA occurs when there are multiple instances of data observations for each combination of levels between the two factors. Each unique combination of levels of the two factors is called a treatment cell. It is important to note that only one of the two factors will always be replicated
