| Abstract: |
| This paper proves χ2 distribution and its nature, and the statistical quantity of the distribution of (n-1)s2)/σ2 by mathematical induction, which is easily comprehensible to teaders knowing little about infinitesimal calculus or ignorant of linear algebra. |
| Key words: χ2 distribution,statistical quantity smathematical induction |
