Psyc 450 Lab Homework #5 3-way BG ANOVA Walk-through 3-way_turtle.sav Two species of turtles (painted and snappers) were offered three different foods (live crickets, ground meat, or lettuce) at two different ages (3 days & 3 months) and the number of feeding attempts were observed. Draw and label the design below – compose the boxes to explore the 3-way interaction looking at the simple interaction of species and food for each age. Obtain the ANOVA and fill in the cell and marginal means above. For the 3-way F= _____________ df = ____, ________ MSe = __________ p = _________, r = _________ Computing the LSDmmd k = ______ n = _______ dferror = _________ MSerror = ________ LSDmmd = ________ Using the LSDmmd, put in <, > & = above to describe the 3-way. Describe the 3-way in words below Draw the boxes for the species * food 2-way below and fill in those semi-marginal means For the species * food 2-way F= _____________ df = ____, ________ MSe = __________ p = _________, r = _________ Computing the LSDmmd k = ______ n = _______ dferror = _________ MSerror = ________ LSDmmd = ________ Using the LSDmmd, put in <, > & = above to describe the 2-way. Compare the pattern of the 2-way above with the pattern of the corresponding simple 2-ways on the last page. Is this 2-way interaction descriptive or potentially misleading? Describe the 2-way in words below. Draw the boxes for the stress * total social support below and fill in those semi-marginal means For the stress* social support 2-way F= _____________ df = ____, ________ MSe = __________ p = _________, r = _________ Computing the LSDmmd k = ______ n = _______ dferror = _________ MSerror = ________ LSDmmd = ________ Using the LSDmmd, put in <, > & = above to describe the 2-way. Compare the pattern of the 2-way above with the pattern of the corresponding simple 2-ways on the last page. Is this 2-way interaction descriptive or potentially misleading? Describe the 2-way in words below. Draw the boxes for the gender main effect below and fill in those marginal means For the gender main effect F= _____________ df = ____, ________ MSe = __________ p = _________, r = _________ Computing the LSDmmd k = ______ n = _______ dferror = _________ MSerror = ________ LSDmmd = ________ Using the LSDmmd, put in <, > & = above to describe the 2-way. Compare the pattern of the main effect above with the pattern of the corresponding simple effects on the last page. Is this main effect descriptive or potentially misleading? Describe the main effect in words below. Draw the boxes for the stress main effect below and fill in those marginal means For the stress main effect F= _____________ df = ____, ________ MSe = __________ p = _________, r = _________ Computing the LSDmmd k = ______ n = _______ dferror = _________ MSerror = ________ LSDmmd = ________ Using the LSDmmd, put in <, > & = above to describe the 2-way. Compare the pattern of the main effect above with the pattern of the corresponding simple effects on the last page. Is this main effect descriptive or potentially misleading? Describe the main effect in words below.
