#### Example 1

#### Average annual rainfall in various states of Mathematics Land and that of other countries

The rainfall for the various states in Mathematics Land has been collected for the years 2003–2005. The states are Euclid, Euler, Newton, Gauss, Fermet, Kepler and Maxwell.

Many comparisons of rainfall could be made. For example:

- for one year between the states
- for a number of years for one particular state
- of countries from around the world which are on the same latitude – north or south – or longitude.

Year | Euclid | Euler | Newton | Gauss | Fermat | Kepler | Maxwell |
---|---|---|---|---|---|---|---|

2005 | 306 | 477 | 478 | 1250 | 206 | 616 | 498 |

2004 | 463 | 637 | 610 | 1223 | 214 | 578 | 493 |

2003 | 388 | 686 | 518 | 1227 | 260 | 611 | 484 |

Historical Average< | 352 | 548 | 630 | 1168 | 236 | 654 | 566 |
