Hi.

I was wondering if it was possible to work out the correlation between three
variables in excel, not just two.

My data looks like this (this is just an example, with random values):

A B C
15,283,741,924 22,891,175,671 182,489,383
12,450,453,827 25,604,121,237 458,039,634
25,017,912,202 10,105,478,615 408,312,030
15,608,597,275 27,352,700,295 71,393,406
6,293,126,663 33,730,623,537 699,182,754
15,665,042,562 25,952,123,256 76,238,591
11,565,224,759 30,426,279,924 44,724,721
8,716,353,737 33,395,986,265 135,495,541
11,234,337,068 23,463,987,625 1,163,192,672
16,285,868,769 21,238,873,761 1,777,205,148
10,406,955,459 31,623,688,840 71,934,583
5,827,079,717 38,907,282,319 964,824,980
11,626,458,649 21,043,475,527 35,381,302
4,081,044,992 41,239,034,015 835,902,380


I've already used the correl function to work out the two-variable
correlations between columns A/B, B/C and A/C. I'd now like to work out the
three-variable correlation between columns A/B/C. Is this possible?

Thanks,
Eileen.

PS I apologise if this query appears twice. I already tried to post it, but
then couldn't find it, so I assumed there was a
problem with the post.

I don't think Excel can handle trivariate / multivariate correlation.

Try a look here for a trivariate scatterplot:

Eileen -

How do you define "three-variable correlation"?
