So they ask what's meant by the term linear regression.
00:07
Well, regression is something called curve fitting because equations, when you graph them, we get curves that we see on the graphing calculator, and we can get information about them.
00:20
I think this might be 1 over x plus 2.
00:27
Let's see.
00:29
It should look more like this.
00:31
So this is a curve related to our equation.
00:35
But maybe we had data points like this and data points like this that we measured in an experiment.
00:43
Because when you measure data, you don't really measure curves that easily.
00:47
You measure data.
00:51
And what's the curve that best fits this? actually, it's 1 over x plus 2 because i drew them.
00:58
I drew our data points to be like that.
01:00
But if you collected your data points and they were in that pattern, this might actually be a great curve to try...
