If you wanted to examine whether television viewing through social learning differs based on students' grade in school (i.e. ,first,second,third) ,what is the dependent variable of interest?

A) grade level
B) television viewing
C) students
D) school

The dependent variable of interest is the variable that is being influenced or changed by the independent variable (in this case, grade level). In this study, the researchers are interested in examining whether television viewing differs based on students' grade level, so the dependent variable of interest is television viewing. The independent variable is grade level, as this is the variable that the researchers are manipulating (i.e., comparing different grade levels). "Grade level" is not the dependent variable, as it is not being measured or changed by any other variable in the study. "Students" and "school" are not the dependent variable or independent variable in this particular study; they are simply the population and setting of the study, respectively.
