Question
The purpose of the following problems is to help you solidify your understanding of the nature of and relation between main effects and interactions and how tables demonstrate those effects. We are going to interpret a number of different possible outcomes for the following study. The study tests differences between cognitive abilities of older and younger adults. Specifically, we are interested in whether the type of task makes a difference. So, we collect a sample of older adults and younger adults and give them two types of tests: (a) a semantic tests where they answer questions (kind of like jeopardy question), and (b) a memory test where they have to recall a list of random numbers. Describe the factors and levels: Factor 1 is __________ and it has two levels ________ and __________. Factor 2 is __________ and it has two levels ________ and __________. Group 1 will consist of _______ adults completing _______ Group 2 will consist of _______ adults completing _______ Group 3 will consist of _______ adults completing _______ Group 4 will consist of _______ adults completing _______ Describe the dependent variable: Here is the graph of the data, which main effect might be significant?Explanation / Answer
Factor 1 is age and it has two levels : older and younger adults
Factor 2 is task and it has two levels: semantic test and memory test
Group 1 will consist of older adults completing semantic tests
Group 2 will consist of older adults completing memory tests
Group 3 will consist of younger adults completing semantic tests
Group 4 will consist of younger adults completing memory tests
Dependent variable is the score obtained in the test.
Task (semantic /memory ) main effect is signficant as semantic line is above the digits line
