A social scientist and an economist working together want to discover if there is a correlation between income and happiness. The researchers recruit a group of participants and ask them to complete a confidential survey. This self-administered survey asks for the participant’s annual income; it also includes the Acme Life Happiness Scale (ALHS), which renders a score between 0 and 100 (0 = Very unhappy . . . 100 = Very happy).
Data set: Ch 11 – Exercise 03A.sav
Variable: Income
Definition: Annual income in dollars rounded to the nearest thousand
Type: Continuous
Variable: ALHS
Definition: Score on the Acme Life Happiness Scale
Type: Continuous (0 = Very unhappy . . . 100 = Very happy)

a. Write the hypotheses.
b. Run the criteria of the pretest checklist (normality [for both variables], linearity, homoscedasticity) and discuss your findings.
c. Run the bivariate correlation, scatterplot with regression line, and descriptive statistics for both variables and document your findings (r and Sig. [p value], ns, means, standard deviations) and hypothesis resolution.
d. Write an abstract under 200 words detailing a summary of the study, the bivariate correlation, hypothesis resolution, and implications of your findings.
