Suppose you are designing a study to test whether a person's physical health predicts happiness even when accounting for their socioeconomic status (measured via income). Apply your knowledge of multiple regression to state the specific predictors you would enter into the regression model and what the regression coefficient for physical health will specifically indicate.
Question: Suppose you are designing a study to test whether a person's physical health predicts happiness even when accounting for their socioeconomic status (measured via income). Apply your knowledge of multiple regression to state the specific predictors you would enter into the regression model and what the regression coefficient for physical health will specifically indicate.
Sample answer: The predictor variables entered into the multiple regression model should be both income and physical health. The regression coefficient for physical health will indicate whether physical health predicts happiness after statistically controlling for income, representing the relationship between the part of health unrelated to income and happiness.
Key points:
- Specify income and physical health as the predictor variables.
- Specify happiness as the outcome/dependent variable.
- State that the coefficient for health represents its prediction of happiness after controlling for income.
Rubric: The response must specify entering both income and physical health as predictor variables in the regression model. It must also apply the concept of statistical control by stating that the coefficient for physical health represents its relationship with happiness while controlling for income (or the relationship of the portion of health unrelated to income).

In a study investigating how income and health relate to happiness, what is the primary reason for including both income and health as predictor variables in a multiple regression analysis?
In a study investigating how income and health relate to happiness, a researcher uses a statistical analysis that includes both as predictor variables to account for their correlation. Match each part of this analysis with its specific function.
In a study investigating income, health, and happiness, a researcher finds that while income is correlated with happiness, it is no longer a significant predictor once health is included in a multiple regression analysis. This result suggests that the initial relationship between income and happiness was likely due to the fact that higher income is associated with better health.
A researcher studying how income and health relate to happiness finds that income and health are correlated. Arrange the logical steps required to use multiple regression to determine the independent contribution of income to happiness.
You are tasked with designing a new analytical framework to investigate whether the relationship between income and happiness is independent of a person's physical health. Which of the following statistical designs would you construct to effectively isolate the unique contribution of income to happiness while statistically controlling for health?
If a researcher investigates how income and health relate to happiness and faces a confound because the two variables are correlated, they can use a _____ analysis to statistically control for one while examining the other.
A researcher finds that income and happiness are correlated, but suspects that health is a confound. After running a multiple regression with both income and health as predictors, the relationship between income and happiness disappears once health is statistically controlled. The researcher should evaluate the original income–happiness correlation as _____.
A researcher finds a strong positive correlation between health and happiness (r = 0.60) and concludes that health independently predicts happiness after accounting for the influence of income. This conclusion is justified without conducting a multiple regression analysis.
In the income–health–happiness multiple regression study, match each statistical element to what it specifically represents about the predictors and their relationship to happiness.
A research team wants to determine whether income and health each independently predict happiness. Arrange the following steps in the order that best reflects sound methodological reasoning for deciding to use—and then evaluating the results of—a multiple regression analysis.
State the primary statistical challenge that arises when examining the relationships of both income and health to happiness at the same time, and explain how a researcher uses multiple regression to address this challenge.
Explain why simply running two separate simple correlation analyses (income-happiness and health-happiness) would be insufficient to address the researcher's concern. How does multiple regression help the researcher comprehend the unique influence of each predictor in this scenario?
