Random Sampling Quick Check

Answer 1

1. What is random sampling?
Random sampling is a method of selecting a sample from a population in such a way that each member of the population has an equal chance of being chosen.

2. Why is random sampling important in research?
Random sampling is important in research because it helps to ensure that the sample is representative of the population. This allows researchers to make valid inferences about the population based on the characteristics of the sample.

3. How can researchers ensure that a random sample is truly random?
Researchers can ensure that a random sample is truly random by using techniques such as simple random sampling, where each member of the population has an equal chance of being selected, or stratified random sampling, where the population is divided into subgroups and a random sample is taken from each subgroup.

4. What are some limitations of random sampling?
Some limitations of random sampling include the potential for sampling bias if certain members of the population are more likely to be selected, the need for a complete list of the population in order to conduct random sampling, and the time and cost involved in selecting and contacting random samples.
