The segmentation interval can be determined as 10.
Then divide all the numbers into 10 segments.
The first paragraph:1~10; The second paragraph:11~ 20; ……; Paragraph 10: 9 1~ 100
The first paragraph takes any number (determined by simple random sampling), such as 3, then the second paragraph takes 13, the third paragraph takes 23, and so on, and the tenth paragraph takes 93.
* * * 3 13, 23, 93 * * * 10 individuals were obtained to form the whole sample.
