Which of the following refers to the scenario in which the relationship between the dependent variable and one independent variable is different at different values of a second independent variable?

Researchers ran a multiple linear regression to determine if belief accuracy in a political claim when given misinformation was related to the following independent variables: One’s level of anger (coded low = 0, high = 1) One’s level of anxiety (coded low = 0, high = 1) Whether the source of misinformation about the claim came from their own political party (in-party, coded from the other party = 0, from their party = 1) Whether or not a correction of misinformation was made (coded correction without evidence = 0, correction with evidence = 1) One’s political knowledge (continuous measurement from 0-4) One of the two issues in question (coded illegal immigration = 0, death penalty = 1) 4. The Adjusted R2 for Model 3 is 0.193. How would one interpret this? 5. In putting together a final model, would you want to remove any variables from Model 3? Why or why not? 6. They did not report standardized regression coefficients (β’s). What would the standardized regression…

I am determining how effective a Drug is at reducing inflammation in individuals infected with a virus. the serum levels of antibody are measured as a measure of inflammation (less antibodies means less inflammation which decreases virus mortality) in 30 people given placebo, 30 people given 1 unit of the drug, and 30 people given 2 units of the drug. I would like to determine what levels of the drug are effective, and if there are sex-specific effects. What are the dependent and independent variables in this experiment?  age _________ sex __________ antibody level _____________ treatment ___________

What is the Independent variable and the dependent variable of this problem?   A neuropsychologist is studying brainlateralization—the degree to which thecontrol of various cognitive functions islocalized more in one cerebral hemispherethan the other. This researcher is awarethat for men, being right-handed seemsto be associated with a greater degree oflateralization than does being left-handedbut that this relationship may not applyto women, who seem to be less lateralizedin general. Various tasks are used in combination to derive a lateralization scorefor each subject as shown in the followingtable.
