True. Correlation does not equal causation.

For example: I have not had any bananas in my house since my wife died 4-1/2 years ago. I have not slipped and fallen at home since my wife died 4-1/2 years ago. Ergo, eliminating bananas in the home prevents slip-fall accidents.

No, that's not really an example of calculating a correlation.

You need at least three pairs of values. The degrees of freedom to establish significance for a regression is Number of Pairs - 2.

It is also true that you couldn't do a non parametric with just one observation pair.

We need some more households. If we could establish a predictive, significant relationship then experimental methods might show us causality.
