One way analysis of varianceVariability is divided Remember, one-way = one IV Number of cookies sold None Bike Hawaii trip Incentives Total variability Between group variability (only one factor) Within group variability (error variance) This will be our numerator – like difference between means This will be our denominator – like within group variabilityRemember, error variance = random error
Two-way analysis of varianceVariance is divided further College Number of cookies sold Elementary Remember, two-way = two IV None Bike Hawaii trip Total variability Between group variability Within group variability Remember, factor = independent variable Remember, within group variability = error variability= random error Factor A Variability Factor B Variability Interaction Variability
