Question: To demonstrate the practical uses of basic learning principles, a psychologist with an interest in behavior modification designed a study on the impact of teaching self-care skills to severely developmentally handicapped children. He randomly assigned and equal number of children to each of three groups, treatment group 1, treatment group 2 and a control group. Group I received reinforcement for activities related self-care. Group 2, received an equivalent amount of attention but no reinforcement and the control group received neither reinforcement nor the extra attention. The children were scored (blind) by a rater on a 10-point scale of self-sufficiency. The ratings were done in a baseline session and at the end of training. The data is provided in table.

a) State the design that applies to the problem and using SPSS, run the appropriate analysis of variance. When reporting the results, summarize the results from the different portions of your SPSS output in one table. The summary should look like Table 14.3 (c), or 14.4 (c) etc. in Howell whichever you find to be relevant. (3pts)

b) Plot and comment on the results (2 pts)

c) Include a diagram illustrating the breakdown of the total variation (SS) and the corresponding degrees of freedom (include the actual figures both both) into the various sources that account and do not account for the total variation. (2pt)

d) Write out in words (or statistically) the main hypotheses being tested in this problem. (2 pts)

e) State your final conclusions, how you reached those conclusions (i.e., what stats you used etc.). I am looking for more than just significant or not significant results. (3 pts)
