So in this question, we're given some data on internet users per 100 people and the number of scientific award winners per 10 million people for various countries.
00:12
And we have two questions here.
00:13
One is a scatterplot of the data, and one is to compute the correlation coefficient.
00:19
So just as a general thing, there's not a lot of data here.
00:23
We can probably just go through and look at these scatterplots ourselves.
00:26
Internet users on the x -axis.
00:28
It's kind of misleading, i guess.
00:29
This starts at 30, goes to 90.
00:33
And the y -axis is 0 to 12.
00:35
So let's just go through and plot some and see if we can immediately see a pattern.
00:39
So when internet users is 78 .4, award winners is 5 .6.
00:45
So i don't know.
00:46
Looking very roughly, it looks like maybe a point there.
00:50
When internet users is 78 .8, award winners is 8 .9.
00:57
Those are really close points, 78.
00:58
So there's kind of two points almost directly above each other right there.
01:02
And then internet users is 57 .2.
01:04
It goes down to 3 .4.
01:07
So 57 .2, maybe the middle -ish of this range.
01:10
Goes down to 3 .4, something like that.
01:14
And 67 .6 goes down to 1 .7...
