Suppose a company has 500 employees and wishes to select a simple random sample of 25. Which would be the more appropriate way of doing so?
Choose 25 pages of the employee directory, and take the first name from each page
Number the employees 1 to 500 in random order and take the first 25 names on the list.
I find both methods to be viable since they both allow every employee to have an equal chance of being selected. But apparently there's only 1 correct answer.
