ANOVA
  1. ANOVAs Basics
    1. Deal with differences between/ among means of a sample
      1. No restrictions on the number of means
        1. ANOVAs allow more than one IV
          1. IVs= factors Conditions= levels of factors
            1. Between subject factors: levels vary between participants
              1. Within subject factors: levels vary within a participant
                1. Reporting findings: F(x,xx)= x.xx, p= (<) xx.xx
                  1. ANOVA less likely to make a type 1 error than a t-test when there= 2+ IVs
                  2. F Ratio
                    1. Variance due to IV/ Error variance = F
                      1. Small F= error variance larger than IV varience
                        1. Large F= error variance smaller than IV variance
                          1. Large F= more likelihood variances caused by IV
                        2. Degrees of Freedom
                          1. Two figures need
                            1. Df- No of levels -1, then N - number of levels
                            2. Reading (one way) ANOVA output
                              1. DF: Condition df needed, error df needed. Total= sample size
                              2. Two-way ANOVA
                                1. 2 factors
                                  1. x*x e.g 2*2
                                    1. Need 3 sig. tests as= 2 main effects, 1 interaction
                                      1. Examine interaction first, if that not present examine main effects
                                        1. Interaction: the way in which the two factors interact.An interaction is when one variable behaves differently in each condition of the other variable
