It is incumbent on the researcher to clearly define the target population. Sometimes, the entire population is small enough to be included in the study. In other instances, the population is too large for the researcher to attempt to survey all of its members. Therefore, a small, but carefully chosen sample is used to represent the population. The sample is the actual group targeted either directly or indirectly and reflects the characteristics of the population from which it is drawn.
Using the Internet, research, analyze, and select at least two articles on sampling methodology used in public health research studies.

Sampling Methodologies Used In Public Health Research Studies
Researching the whole population is often impractical, especially when the population is large or covers a wide geographical area. Researchers opt to use samples that are a representation of the whole population. A sample is a small and reasonable portion of the population. There are many sampling techniques to choose from, depending on various factors. A large sample is more desirable since results are more reliable, but it is hard to work with. Therefore, sample size matters, but it depends on the type of research underway. The paper covers two articles, one utilizing a simple random sampling method, and the other used the convenience sampling methodology. It seeks to analyze sampling techniques applied in research articles related to public health research.
Gupta, Khan, Rajoura, and Srivastava (2018) studied internet addiction and its mental health issues among college students. The researchers used simple random sampling to collect participants from three colleges of the same university. The study aims to explore the prevalence of internet addiction among college students. To obtain a representation of the population without bias, the researchers opted for the simple random sampling method where all students had an equal and known chance of being selected.

The computation takes a lot of time and effort. The researcher will also have to invest a lot to conduct background research of the population and what behaviors or attributes will be used to generate random numbers. Researchers prefer convenience sampling since they can collect data quickly, inexpensive in sample gathering, the samples are readily available, and fewer rules in the selection (Lavrakas, 2008). However, the results from convenience sampling can be challenging to generalize. The sample can be an under- or over-representation of the group. There are higher chances of biased results if the group does not display most of the whole population’s characteristics.
