What is systematic sampling and how is it used?
Systematic sampling is a method where you select samples based on a fixed, periodic interval. For example, if you have a list of 1000 items and want to sample 100, you might select every 10th item.
Can you give me an example of how to implement it?
Sure! If you have a population of 1000 and want a sample of 100, you would choose a random starting point between 1 and 10, then select every 10th item from there.
What are the advantages of using systematic sampling?
Some advantages include simplicity, ease of implementation, and the ability to ensure a spread across the population.
Are there any disadvantages I should be aware of?
Yes, if there's a hidden pattern in the population, systematic sampling can lead to biased results. It's important to ensure randomness in your starting point.
