- In general, what are some problems with using regression to measure causal effects?arrow_forwardA researcher would like to evaluate the claim that drinking large quantities of water can help prevent the common cold. One group of participants drinks 8 glasses of water every day, and a second group drinks 2 glasses of water every day. The researcher records the number of colds each individual experiences during the 4-month winter season. what is the independent variable? what research method is being used experimental or correlational?arrow_forwardSuppose there is a significant correlation between two variables. Describe a case under which it might be inappropriate to use the linear regression equation for prediction.arrow_forward
- If the omitted variable is negatively correlated with the treatment and has a positive impact on the outcome, the true causal effect is bigger than the estimated effect.

In order to confirm the existence of the focal relationship, they decided to control for immigration status by adding a variable measuring the number of each survey respondent's grandparents who were born outside the U.S. The researchers wonder if immigration background could influence both income and TV watching (but they hope this is not true, because it could invalidate the focal relationship). The researchers conduct a multivariate regression by adding a measure of number of grandparents born outside the U.S. to the regression equation presented in Equation 1 of Table 1. The results of the second regression equation are presented in Equation 2 of Table 1. Table 1.

However, they are concerned that this relationship only exists because of conscientiousness (variable Z). Specifically, conscientious people tend to get more sleep and also tend to perform well on tests. Using the data below, please determine where there is a relationship between hours of sleep one gets the night before an exam and performance on the exam after accounting for the role of conscientiousness (alpha = .05, two-tailed). sleep exam grade conscientiousness 6 63 2 66 4 1 60 2.5 4 75 3.5 90 9. 88 4.5 10 92 6 a) What type statistical analysis should you perform? Please explain your rationale b) Please state the null and alternative hypotheses c) Please write out the results and make a decision d) Please make a general conclusion (no stat talk)arrow_forwardWhich of the following is not determined in the case of multiple linear regression? A) Potential confounding effects from “lurking” variables included in the analysis B) Observed relationship between predictor and outcome variables adjusting for confounding relationshipsC) Causal relationships between predictor and outcome variables adjusting for confounding relationships D) Potential observed interaction effects between variablesarrow_forward
- What is the difference between an interaction term and a main effect in multiple linear regression?arrow_forwardI need help with this question 1. Are the main effects significant? Explainarrow_forwardA study found a positive correlation between IQ and making good economic choices. One possible reason for this association is causation: higher IQs result in better economic choices. But lurking variables may explain some of the correlation. Suggest some additional factors that would explain why people with higher IQs may make good economic choices.arrow_forward
