How much would it be to finish this project by tomorrow by 11am Pacific time?
Project #2 – Psychology 143 Spring 2019 – Yockey Project 2 – Psychology 143 Name ____________________________________________ Project #2 – Psychology 143 Spring 2019 – Yockey Complete each of the following problems, answering each question as completely as possible. You will need to use SPSS to answer a number of the questions. You may use your text and any other class materials as needed. The project is due by 5/7 at 2 pm (you are welcome to turn it in early if you like). You may either 1) email the project to me as an attachment (as a Word or PDF file please) or 2) turn it in at the psychology office (where it will be date and time stamped). SPSS output is not required to be turned in with your project. 9 1. The following output is from a multiple regression analysis that was run on the variables FEARDTH (fear of death) IMPORTRE (importance of religion), AVOIDDTH (avoidance of death), LAS (meaning in life), and MATRLSM (materialistic attitudes). In the regression analysis, FEARDTH is the criterion variable (Y) and IMPORTRE, AVOIDDTH, LAS, and MATRLSM are the predictors (Xs). The SPSS output is provided below, followed by a number of questions (12 points total). Descriptive Statistics Mean Std.

Dependent Variable: feardth Answer the following questions for the regression procedure: a. How many people were in the study? _____________ (1 point) b. What is R2 for the regression analysis? ________________ (2 points) c. Is R2 significant? Report the appropriate statistical criteria to support your answer (do not just provide the p-value, but the APA formatted information as appropriate) (3 points). d. Which predictor(s), if any, are significant? Which predictor(s), if any, are not significant? Be sure to (1) indicate whether each predictor is significant or not and (2) report the corresponding t values and p-values for each of the predictors (whether significant or not) below (4 points). e. Write the final equation for the regression model. (Consult your text as needed for details on writing the regression equation.) (2 points) 2. A research study was conducted to assess the effectiveness of an 8-week GRE study preparation course (e.g., Kaplan) on GRE test scores. Six subjects were selected to participate in the study, and took the GRE test on three occasions, with the prep course employed for an eight week period starting after the first study session (week 0). The dependent variable is the GRE score, with higher scores indicating better performance on the test (10 points total). GRE week 0 GRE week 4 GRE week 8 Subject 1 980 1070 1180 Subject 2 1030 1040 1240 Subject 3 1010 970 1260 Subject 4 930 1040 1110 Subject 5 1010 1110 1140 Subject 6 1130 1050 1210 a. State the null and alternative hypotheses for the overall test (2 points). b. Interpret the results of the SPSS output below (use α = .05). Describe the results in the context of the study and use APA format as appropriate. If the overall test is significant, be sure to conduct and report the results (in APA format) of any further tests as appropriate (use a total α = .05 for the set of follow-up tests) (8 points). 3. A researcher was interested in examining if a relationship existed between two variables, X and Y. Five people were selected for the study, and their scores on X and Y are shown below (8 points total). X Y 12 14 9 11 13 17 11 19 14 13 a. State the null and alternative hypotheses below (2 points). b. Report the results of the hypothesis test below. Be sure to express the results in the context of the study and use APA format as appropriate. Use α = .05 (6 points). 4. An experiment was conducted to examine the performance (as measured by the number of errors made) on a motor skills task. Twenty-four subjects (12 young and 12 old) were assigned to either an easy or hard motor skills task. There were two factors in the study: age (young/old) and difficulty of the motor skills task (easy/hard). The number of errors made on the motor skills task was recorded for each person and is presented in the table below (15 points). Difficulty Easy Hard Age Young 3 4 2 6 3 6 6 5 8 9 9 7 Old 5 7 6 4 2 4 10 11 14 15 16 17 a. State the null and alternative hypotheses below (2 points). b. Report the results of the hypothesis tests in #a below. Be sure to express the results in the context of the study and use APA format as appropriate. Sketch, label, and describe any significant interaction(s). (For your sketch, it is fine to make it look like the plot shown in SPSS.) Use α = .05 for each test (13 points) CONTINUED ON THE NEXT PAGE Extra Credit (2 points). Provide an example (that has not been used in class or in your text) of a two-way between subjects ANOVA. For full extra credit, state each IV (including all levels) and the DV in sufficient detail below so that I am able to properly evaluate your example as being appropriate for the two-way ANOVA. It is not necessary to provide values (i.e., data) with your example. This completes the project. Congratulations on finishing project #2!
