Okay, so to answer this question, we have to know of the difference between the independent variable and the dependent variable.
00:06
The dependent variable is what is being measured in the experiment.
00:14
And the independent variable is what you are manipulating or changing.
00:20
And you're measuring to see if the independent variable is having an impact on the dependent variable.
00:27
So let's take a look at some of these problems.
00:29
In a, we're studying where the scores on a final exam are influenced by background music that is soft, loud, or absent.
00:38
So what we are changing is the music, so that's the iv, and the different conditions are soft, loud, or absent.
00:56
And what we are measuring is the final exam scores.
01:11
Let's take a look at b, comparing freshmen, sophomores, juniors, and seniors with respect to how much fun they have during the college semester.
01:20
So we're measuring how much fun these students are having during the college semester, and the independent variable is the class year, and the different conditions are freshmen, sophomores, juniors, seniors...
