Let's do this problem on the desmos graphing calculator.
00:04
You can add a table and with this table we can enter the data for the iq.
00:11
So it's 92 and then the sat was 730.
00:15
We have 95 and 780, 97 and 820, 99 and 990, 102 and 830, 104 and 870, 106 and 1010, 110 and 1000, 114 and 1040, and 120 and 1150.
00:45
We can see the data plotted and now what we can do is we can run a regression.
00:57
We're using the x1, the iq, as the independent variable, but i think it's called x1 here, and the dependent is y.
01:05
So y1 is approximately whatever variables you might want to call it, like a plus b x1 for instance...
