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).

a. Dependent Variable: feardth

1. 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).

a. Write the final equation for the regression model. (Consult your text as needed for details on writing the regression equation.)

Homework Answers

Answer #1

(1) Here, the predictor variables are - importre, avoiddth, Las and matrlsm. For importre, the T value is -0.838 and p-value is 0.403 (non-significant). For avoiddth, the T value is 10.004 and the p-value is 0.000 (significant). For Las, the T value is -4.247 and the p-value is 0.000 (significant). For matrlsm, the T value is 0.885 and the p-value is 0.378 (non-significant). The significant predictor variables are avoiddth and Las, since the corresponding p-values are less than 0.05. The non-significant predictor variables are importre and matrlsm, since the corresponding p-values are greater than 0.05.

(a) The final equation for the regression model: = 27.738 + (-0.167) importre + (0.697) avoiddth + (-0.213) Las + (0.044) matrlsm.

Regression: First, choose any metric variable as the dependent variable and then choose any three other metric variables as independent variables. HOWEVER, this process must be repeated until you find a model that produces a significant F-calc (p-value (sig) <.05). Thus, you may have to sort through several combinations of dependent and independent variables before finding a combination that produces a significant F-calc. This is actually quite easy to do in SPSS using the drop down menus as shown in...
