## anonymous one year ago The graph below plots the values of y for different values of x: Which correlation coefficient best matches the data plotted on the graph? 0.5 0.8 0.9 1.0

@DanJS hey can you help?

3. anonymous

@triciaal

4. triciaal

what is the correlation coefficient?

5. anonymous

uum, i dont know

6. triciaal

sorry phone

7. triciaal

let us find the slope

8. triciaal

change in y / change in x = y2 -y1/ x2 -x1 for 2 points on the line (x1,y1) and (x2, y2)

9. anonymous

what do i put in for x and y?

10. triciaal

give me a min stats not my best let me verify correlation

11. anonymous

okay

12. triciaal

the slope is for the "best fit" line

13. anonymous

okay

14. triciaal

found a formula but even the shortcut is long I need to pass, sorry. will try to solicit more help for you

15. triciaal

@jdoe0001 @SolomonZelman stats?

16. anonymous

OK but thankyou for trying :)

Can you help?

30. Keigh2015

I will try, this in not my best subject

31. triciaal

@Keigh2015 you too

32. Keigh2015

you too what?

33. anonymous

Can you?

34. Keigh2015

I don't know still trying to look at all of it and make sense of it all, but i will try.

35. anonymous

Okay

36. triciaal

@Keigh2015 meant this/stats is not your best subject

37. Keigh2015

Ok so, I can't figure out which function it would be, but probably a positive cubic function. The spacing between the points seems to be 1.0 (1 unit exactly). Oh yeah this is not my best subject @triciaal

ill just put that, its been forever on this question
