Hello 大家好呀，继上一次分享过有关AP化学的备考经验，我又来分享关于AP统计学的一些心得体会啦~

## AP统计大题答题策略以及解析

### 例1：

In each of the ( ), number each of the ( ) from 1 to n, where n is the number of ( ) in that ( ). Within each ( ), obtain a simple random sample of ( ) by using a random number generator to generate unique random integers from 1 to n. Select the ( ) corresponding to the integers and measure the ( ).

step 1: classifying the population into groups of similar individuals

step 2: choose a separate SRS in each stratum and combine these SRSs to form the sample.

SRS:

1. Label. Give each individual in the population a distinct numerical label from 1 to N

2. Randomize. Use a random number generator to obtain n different integers from 1 to N.
