For this problem, we know that we want to determine the option most likely to have a negative correlation.
00:08
So when we talk about something or two factors having negative correlation, that means basically as x, one factor, goes up, y goes down.
00:33
So the idea is that the increase in one negatively affects the value of the other.
00:41
So if we're going from bottom left to top right, that is positive relation.
00:47
X goes up, y goes up as well.
00:50
If as x goes up, y goes down, then that would be negative correlation.
00:55
Looking at the different options, we know that, well, for option a, you have that babies grow over time.
01:04
So we would expect that older babies are probably going to be larger and therefore heavier.
01:10
So that would be a positive correlation...
