Ok, so the explanatory variable is what you control and what you think explains the variation in the response variable.
00:22
And the response variable is what is the variable that depends on the explanatory variable.
00:45
And so here the two variables that we've got is whether a patient took medication and their blood pressure and probability of developing diabetes.
01:13
And so the one that we can control and whether we can see it affects the other one is whether or not they took medication.
01:23
So the explanatory variable is going to be whether they took medication, because we want to see if the medication has an effect.
01:36
So we get some people to take it, some people to not take it, and then measure blood pressure and see what happens.
01:41
And the response variable is sort of the effect of that medication.
01:48
So we want to see whether that medication lowers or raises the blood pressure or has no effect.
01:55
So blood pressure is the response variable...
