tests for the A, B and A × B effects, controlling the familywise
error rate at .05, and draw appropriate conclusions.
Use the test procedure commensurate with the analysis in part

appropriate, controlling the FWER at .05. Provide an account of any
directional inference(s) that follow from your test outcomes
Question 2 A 3 x 3 factorial experiment examining the impact of encoding strategy on interference in recognition memory is carried out with 11 participants per cell (1 = 3, K = 3, N = 99). The factors and factor levels are: A: Encoding Strategy aj: No strategy az: Featural az: Semantic B: Type of interference bi: Similar spelling (from foils) b2: Similar meaning b3: Unrelated Participants are asked to study a list of words and then given a memory test. Factor A is encoding strategy - before studying the list of words, participants are given either no additional instructions (No Strategy; (i), or told to focus on the spelling of each word (Featural; az), or told to focus on the meaning of each word (Semantic; a3). Factor B refers to the type of interference that occurs at the time of testing. The test list contains the target words as well as foil words did not appear on the study list. Foil words either have a similar spelling to a word on the study list (bu), or a similar meaning to a word on the study list (bz), or are unrelated to words on the study list (b3). The dependent variable is a recognition memory score, where a high score indicates a greater number of correct responses to the target words on the memory test. Participants are randomly allocated to one of the nine cells in the design. The experimenter decides to conduct a post-hoc standard factorial contrasts analysis beginning with tests of the homogeneity hypothesis for A, B and Ax B effects. Cell means are given below. bi b2 b3 M ai 27 36 30 31 a 28 35 27 30 аз 32 19 36 29 Mk 29 30 31 30 For this example, SSE = 18144.
