What is a common sampling method in research?

Simple random sampling is a widely used sampling method in research because it provides each member of the population with an equal chance of being selected. This method helps to ensure that the sample is representative of the overall population, reducing selection bias. By using a random process to select participants, researchers can generalize their findings to the larger population with greater confidence. This technique is foundational in statistical analysis and is often seen as the gold standard for sampling methods, as it lays the groundwork for many inferential statistics tools that rely on the assumption of randomness in sample selection.

In contrast, biased sampling and other methods may introduce systematic errors or biases that can skew the results and limit the validity of the findings. Therefore, simple random sampling is crucial for achieving more reliable and valid research outcomes.
