This is different from the problem of small sample size outlined above. I'm not talking about a few freak years with lots of pests throwing the statistics out. The problem is that when it's sunny, it generally isn't raining. So the years with lots of sunshine have lower crop yields because they have less rain.

It is possible to correct for this, by looking at records of both sunshine and rainfall. Basically, if you're looking for a direct relationship between two variables, you need to think of all the other variables that might have an effect and take those into account.

Statistics, in general, provide very little information on the intrinsic accuracy of a measurement. Statistics can only provide an estimate of the minimal error that might be in the measurement. The actual error can be much greater than the minimal statistical error. Another way to put it is that statistics measure the variability of a measurment, not the accuracy of a measurment.

There is also a possibility for errors. Uses of national income statistics? National income statistics are used to: Increase in wages for a sector that is generating a large percentage income for the economy.
