So for this problem, i'm going to note that i'm missing the original data for this problem.
00:05
So i don't know exactly what the different variables are, but what i can discuss are the levels of measurement.
00:16
The levels of measurement.
00:22
So the first level of measurement is nominal.
00:29
We can think of that as name only.
00:34
So for a data set, like what we're discussing for this problem, i would expect a variable that would be nominal would be, for instance, the make of the car.
00:48
Then we'd have ordinal, which we can think of as being ranked labels.
01:02
So, for instance, a safety rating, one star, two stars, etc.
01:18
Those aren't specific measurements, they are rankings, but we have that those rankings have an ordering to them...
