Order Description
For the following description and data set, prepare a graph that would accurately portray the results. Write a brief conclusion An A-B-A-B design was used to reduce the number of interruptions made in class by a child whose behavior was disrupting his second-grade class. During treatment, the teacher was instructed to ignore the child’s interruptions and to pay special attention to the child when he was behaving productively (e.g., doing class work). The number of interruptions per 1-hour recording session were as follows: (12 pts) A: 12, 12, 7, 6, 6, 9, 8, 10, 9, 11 B: 9, 8, 9, 4, 3, 2, 2, 1, 4, 2 A: 4, 5, 10, 6, 12, 10, 10, 10, 12, 9 B: 9, 9, 2, 1, 1, 1, 0, 3, 4, 1 Research methods homework A. Robert Woodworth laid the foundation for Lee Cronbach to talk about “the Two Disciplines of Scientific Psychology”. What were those two disciplines? Why are both important? B. For each of the following, identify the I.V. and D.V. and the nature of the I.V. (between or within groups). a. In an attempt to identify the personality characteristics of cell phone users, three groups of college students are identified: those who do not have a cell phone, those who own a cell phone but report using it less than 10 hours per week; and those who own a cell phone and report using it more than 10 hours per week. They are given a personality test that identifies how outgoing they are on a 1 – 100 scale. If the researchers were also interested if gender is related to how outgoing a person is, what type of factorial design could be used? Graph some results that show a main effect of cell phone use in addition to an interaction. b. To determine if maze learning is affected by the type of maze used, 20 rats are randomly assigned to learn a standard alley maze (i.e., includes side walls; located on the lab floor); another 20 learn in an elevated maze (no side walls; raised above floor level). Learning is assumed to occur when the rats run through the maze without making any wrong turns. If the researchers were also interested in if size of reward (small or large) has an effect on learning, what type of factorial design could be used? Graph some potential results that show a main effect of each variable, but no interaction.
