Correlation Calculator

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

Does it work well? Any ideas for improvement?

Re: Correlation Calculator

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.

Re: Correlation Calculator

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.
