Choosing a random sample is an effective way to select participants as everyone has the same chance of being part of the study.

Random sampling makes sure that the findings you get from your sample should be close to what you would have gotten if you had measured the complete population. All the units in the population have an identical chance of being chosen using the simplest random sample.
Researchers can generalize about a particular community and remove bias by using basic random sampling. Without conducting a survey or gathering data from every member of the population, statistical techniques can be used to draw conclusions and make predictions about the population.
