Proposed Solution, Implementation, and Evaluation The final capstone project is
An occupational therapist teaches children fine hand motor co-ordination. Their scores for such co-ordination are presented before the intervention and after the intervention (provide calculations) Before AFter 4 6 5 7 3 8 5 9 2 8 5 10 2. Using a related samples t test, compute the following: What is the final numerator score for the related samples t test? What is the degrees freedom? What is the related samples t score? Using the following data for each participant (n = 6, Test 1 and Test 2). Provide calculations. (It is suggested that you use the following headings for the data). Test 1 (x) Test 2 (V) Xy X^2 Y^2 Test1 (X), Test 2 (y) 2, 2 2, 4 5, 4 4, 4 5, 3 6, 5 Calculate Pearson r. What is the final numerator score from your calculations? C. What is the final denominator score from your calculations? 3. Assume that you wish to compare the effects of an exercise intervention on the fitness level between an experimental group who attend the exercise intervention and a control group who do not. Write: (a) Directional hypothesis (b) Null hypothesis. (Do not use statistical notation – write in words) 4. The pulse rate of patients are stated below in terms of those who took medication (MedA) and those who did not (NonMed). You employ an independent samples t Test, The data are (provide calculations): MedA: 60, 66, 68, 70, 73, 77 NonMed: 70, 75, 86, 100, 124 What is the final numerator score for the t test? What is the degrees freedom for both groups combined? What is the final denominator score for the t test? What is the t score? What is the minimum score for a one-tailed independent samples t test to be statistically significant at the .01 level, assuming that the sample sizes are: Group 1 n = 12, Group 2 n = 9 5. Patients were asked to comment on the care they received in Ward A and in Ward B. The response frequencies were: Ward A: Good 50, Poor 20 Ward B: Good 50, Poor 50. Provide calculations. What is the df? Calculate chi-square. What is the minimum chi square score for these data to be statistically significant at the .01 level?
