The only data that is insufficient to make a prediction is either no data at all, or data suspected to be wrong (e.g. faulty observation equipment).
Even given a single sample, one can make a prediction of what the next observation will be: the same value. Once you get more samples and more knowledge about the subject, you can bring stronger statistical tools to bear to get error estimates, prediction intervals, improved models, etc.

- pfortuny 14y agoIf you have enough data, you have a census and then there is no model, just reality... In polls like this, the more data the better as long as it is unbiased (i.e. as long as it is DATA).
