To draw valid conclusions from your results, you have to carefully decide how you will select a sample that is representative of the group as a whole. This is called asampling method. There are two primary types of sampling methods that you can use in your research: Probability samplinginvolv...
By using cluster sampling, researchers can collect larger samples than other methods because the groups simplify and reduce data collection costs. Clustering effectively concentrates the subjects into smaller regions, allowing the researchers to sample more of them. For example, if they use schools as ...

Probability samplingis asampling methodthat involves randomly selecting a sample, or a part of the population that you want to research. It is also sometimes called random sampling. To qualify as being random, each research unit (e.g., person, business, or organization in your population) must...
The process of coming up with an idea for a research project needs a lot of brainstorming. For that, previous studies done on the same topic are studied. The loopholes found in those studies are the starting point for coming up with an idea....
Probability sampling is widely used in research. It ensures that the sample is representative of the population, allows researchers to estimate the level of uncertainty in the results, and makes it possible to generalize the findings to the population. 1. Simple Random Sampling As the name suggest...
Sampling bias poses a significant threat to the validity of research findings by distorting results toward a particular segment of a target population. This article introduces the concept of sampling bias, highlighting its presence in various fields such as healthcare, education, psychology, and market...
