So for the first one, when would we calculate a mean in the standard deviation? we would want the variables to be quantitative in nature, not categorical or nominal.
00:14
So you can't calculate the mean of students ' hometowns, right? like if my hometown is albany, new york and someone else's hometown is like westchester, new york, you cannot calculate the average of those.

00:29
You can't calculate an average of if someone is heterosexual and someone is homosexual and someone is, you know, and so on.
00:41

00:55
Which statistics incorporate every value in the dataset? that's going to be the mean and the standard deviation.
01:01
Because in order to find the mean, you need to take every single number added up.
01:05
And then divide by the total.
01:06
And then the standard deviation, you subtract all of those values from the mean...
