All right, so we have a study that was done that was looking at the connection between math and music abilities.
00:07
And the study showed that there was a relationship between a person's math and music abilities.
00:14
And the question we're being asked is whether or not that means these variables are independent or dependent.
00:27
That is our question.
00:29
And because the study showed they are related, that means they are dependent.
00:34
And what that means is if we know something about someone's math ability, that would give us some information about their music ability and vice versa.
00:44
So that's why they're dependent.
00:45
One depends upon the other.
00:48
The next scenario is about the relationship between playing violent video games and aggressive bullying behavior.
00:54
And a study showed that there was no relationship between playing violent video games and aggressive bullying behavior.
01:00
And that means that these variables are independent.
01:02
That means knowing something about one of those variables tells you nothing about the other variables.
01:13
So, for example, let's say someone was playing video games...
