How Large is a Large Sample? |

| Authors: | Frank D J Dunstan A Barry J Nix |
| Abstract: | When teaching students about the Central Limit Theorem, it is difficult to give simple guidelines about when its use is justified. We demonstrate that the sample size needed depends to a great extent on the parent distribution and propose a method, based on the use of microcomputers, for helping students to appreciate the theorem and when it can safely be used. |
