However, it is dangerous to use a theory without thorough understanding. Although I do think statistics is important to most routine scientific works. I really like the following two says about statistics. Statisticians know that if you put a man s head in a sauna and his feet in a deep freeze, he will feel pretty good - on the average.

We need more time to do the most important work, interpretation and thinking, or reasoning. If we can do abstract reasoning , we can cut the experiments to minimum.
