中央極限定理
The Central Limit Theorem
1、The mean of the sampling distribution is identical to the population mean.
2、The standard deviation of the distribution of sample means is equal to (sigma) / (the square root of N).The quantity is known as the standard error of the mean.
3、Provided that N is large enough,the shape of the sampling distribution is approximately normal.

少年肯特的後記:
嗯嗯...名字還頗炫!
好像有點抓到訣竅了...就是這樣啊,繼續加油^^
吼吼!最近老是偷懶沒發新聞耶...好啦我會注意!哈哈...
