The best method is to number all students and use random numbers to pick 200 of them.
Solución
The correct answer is: "Number the students on the school roster. Use a table of random numbers to choose 200 students from this roster for the survey."
Explanation:
A simple random sample means that every student in the population has an equal chance of being selected. By numbering the students on the roster and then using a table of random numbers to choose 200 students, you ensure that the selection process is entirely random and unbiased. The other methods either introduce bias or stratify the sampling in a way that does not constitute a simple random sample.

Choosing students based on their random identification numbers from a roster is a tried-and-true method for obtaining a simple random sample. It ensures that every student has an equal chance of being selected, avoiding biases that can arise from considering only students arriving at a specific time or location. Another effective technique is using random numbers to select seats in the gym. This method introduces a fun element, as it can turn into a surprise sampling event, catching students off guard and leading to more genuine responses to the survey. It’s a little like the luck of the draw, creating a fair selection process!
