Have a try of the Correlation Calculator and let me know what you think.

Does it work well? Any ideas for improvement?

Hi MathsIsFun,

I gave arbitrary values of (21,216), (16,50), (10,100), (63,450); I got Pearson's Correlation coefficient : 0.95125.

It certainly works well.

In my opinion, the page is excellent.

Many viewers would love it! Thanks a lot! I don't think further changes are required.

Regarding ideas of improvement, I leave it to other members.

hi MathsIsFun

Another really useful page. Excellent! Seemed to work for my test data.

Are you planning any linear regression pages to follow on from this ? If not, then an option to put on a line would be helpful.
