In research design<\/a>, population and sampling are two important terms. A population is a group of individuals that share common connections. A sample is a subset of the population. The sample size is the number of individuals in a sample. The more representative the sample of thepopulation, the more confident the researcher can be in the quality of the results.<\/p>\n

Types of Sampling Methods<\/h2>\n

Illustration of the importance of sampling:<\/p>\n

A researcher might want to study the adverse health effects associated with working in a coal mine. However, it would be impossible to study a large population of coal workers. So, the researcher would need to narrow down the population and build a sample to collect data. This sample might be a group of coal workers in one city.<\/p><\/blockquote>\n

Sampling methods are as follows:<\/p>\n

Probability Sampling<\/strong> is a method wherein each member of the population has the same probability of being a part of the sample.<\/p>\n

Non-probability Sampling<\/strong> is a method wherein each member of the population does not have an equal chance of being selected. When the researcher desires to choose members selectively,non-probability sampling is considered.\u00a0Both sampling techniques are\u00a0frequently utilized. However, one works better than others depending on research needs.<\/p>\n

Qualitative and Quantitative Research<\/h2>\n

In Qualitative research<\/a>, non-numerical data is used to study elements in their natural settings. This helps to interpret and measure how these elements affect humans or other living beings.
\nThere are three main types of qualitative sampling:<\/p>\n
