Key Concepts

Sample

The sample is the specific, smaller group selected from the population for participation in the study. Here, the sample consists of the 128 students who were randomly chosen from the population to provide data on the number of hours they work per week.

Random Sampling

Random sampling is a sampling method in which every member of the population has an equal chance of being selected. This approach minimizes bias in the selection process and helps ensure that the sample is representative of the population, thereby strengthening the validity of the study’s conclusions.

Population

The population in research refers to the entire group of individuals or elements that share a common characteristic and to which the research findings are intended to be generalized. In the context of the study, the population would encompass all full-time students attending the community college who are working while enrolled.
