So looking at an experiment, we have two groups of college students in different rooms where they drink wine and listen to jazz or they drink water and listen to jazz.
00:11
The wine room has a big window with nice scenery where water room is windowless, dark and dingy.
00:17
What is the floor of the experiment? a, it is low in external validity.
00:22
B, it is low in internal validity.
00:25
C, they did not randomly select participants from all college students, so a sampling error.
00:29
Or d, it is low in realism.
00:32
Okay, so the correct answer here is b.
00:35
Let's go through what these mean for why.
00:38
So first of all, external validity is the ability to apply bindings to the outside world.
00:47
And that doesn't seem to be an issue here, because they're drinking wine, they're listening to jazz.
00:52
If it's found that wine makes people like jazz, that's applicable to the real world.
00:57
B, the problem is the internal validity.
01:01
So this is establishing cause and effect.
01:06
So it's making sure that the reason that they like the jasmore is definitely because they are drinking wine...
