A survey was conducted involving all grade 12 students in a school to determine if there was a relationship between the number of hours of television they watched each week and their overall grade average. In a scatter plot of this data, which is the independent variable?
(It’s just a question there is no image involved)
a) Time
b) Hours of TV watched per week
c) Overall grade average
d) None of above
And Dependent variable?
I'm pretty sure its time. If not then none of the above.
overall grade depends on how many hours watched per week.
To identify the independent variable in the given scenario, we need to understand what an independent variable represents. The independent variable is the one that is manipulated or changed by the researchers in an experiment. It is the variable that is believed to have an effect on the dependent variable.
In this case, the independent variable is the factor that the researchers intentionally manipulate, and the dependent variable is the outcome that is measured or observed.
Looking at the scenario provided, we can see that the researchers are conducting a survey to determine if there is a relationship between the number of hours of television watched each week and the students' overall grade average.
Therefore, the independent variable in this survey would be:
b) Hours of TV watched per week
The researchers are interested in seeing if the number of hours of television watched per week has any impact on the students' overall grade average, so they would manipulate and measure this specific variable.
