00:02
So we have four situations here.
00:02
And we want to say if the correlation is expected to be positive, negative, or nonlinear.
00:08
So the price of a laptop and the age of the laptop, assuming that it's like a used laptop, the higher the age, the older the laptop, the lower we would expect the price to be because it loses value over time.
00:22
So we would expect that this is a negative correlation.
00:26
All right, weight and sprint speed.
00:29
So generally you, i mean, you can train, but on a statistical average, we would expect that if your sprint speed is, well, as your weight goes up, your sprint speed would go down because there's more weight to carry so you'd run less fast.
00:43
So also a negative correlation.
00:47
All right, for number three, height and age of a human.
00:50
So there would be a correlation up until, like, while you're growing...
