All right.
00:01
This question is asking us to be able to identify quantitative variables.
00:05
And so a quantitative variable is any number, or is any variable that can be represented numerically.
00:21
Whereas a quantitative, or sorry, a qualitative with an l variable is something that relies on like categories or other kind of like verbal means of describing, such as color, would be an example of a qualitative variable.
00:36
And so let's look at our different groups and identify whether they're quantitative or qualitative.
00:42
So age, temperature, income, and height are all numbers.
00:47
So these would all be quantitative variables because they're represented numerically.
00:52
Same thing with b.
00:54
This one is a bit trickier, but right here we see gpa.
00:59
This is almost always given as a number on a range from zero to four.
01:06
And so this is a quantitative variable.
01:08
And then we can also think anxiety level implies that there's some kind of like ordinality to it or order.
01:15
So even though you could put it into words like, you know, very high anxiety, high anxiety, medium anxiety, low anxiety.
01:23
These can still be represented on a scale because there's, you know, like they're comparative measures...
