Thank you We speak with this in your calculator and

shmoop which set of points if put in a scatter
- 00:08
plot would show us a positive correlation and hear the

potential answers Hearts waver and let's go All right It

wants us to find which set a point shows a

positive correlation in other words as the independent variable increases
- 00:24
So does the dependent variable The best way to visualize
- 00:27
this thing is to one they could visual so let's
- 00:29
graphic the graph of the first set of data is
- 00:32
shown here and note that as thie x value of
- 00:35
the subsequent point increases so does the y values So
- 00:39
we know that there exists a positive correlation between these
- 00:42
three points will still look at the other sets of
- 00:44
points just to make sure that our answer is correct
- 00:46
Though graph of the second set of points has shown
- 00:49
here well we can see that this time the point
- 00:51
slope downward from the beginning and this is a negative
- 00:54
correlations the opposite of what we want next set is
- 00:57
shown here this time there's a slope of zero The
- 01:00
correlation is neither positive nor negative How about d again
- 01:04
this graph shows the horizontal correlation on lee this time
- 01:07
it's a larger wye valley which still doesn't make the
- 01:10
correlation posit Finally thiss graff has no correlation at all
- 01:14
the values move up and down without any pattern only
- 01:17
a has a positive correlation It looks like our answer's 00:01:19.999 --> [endTime] aye what
