Variables
A smaller subgroup of the population being studied is called a sample. This sample is selected to represent the larger population and allows researchers to draw conclusions and make inferences about the entire group based on the characteristics of the sample.
A relevant population refers to the group of individuals or subjects that the researcher is interested in studying and drawing conclusions about in a research study. It includes those individuals who meet the criteria for participation in the study and whose characteristics are of interest to the researcher.
Population refers to all the individuals or items of interest in a particular group. Statistical population refers to the theoretical concept of all possible individuals or items that could be included in a study, from which a sample is actually drawn. Statistical population is typically larger than the actual population being studied.
The size of a population can get larger with no influences from migration if birthrate is greater than the death rate. This results in a natural increase in population size due to more individuals being born than those dying.
Researchers are using a procedure known as simple random sampling. This involves selecting individuals at random, where every individual has an equal chance of being selected, to ensure the sample is representative of the population.

A sample is termed representative if it possesses similar characteristics to the population being studied. This similarity ensures that the findings from the sample can be generalized to the larger population, enhancing the validity of the research conclusions. A representative sample helps to reduce bias and enables researchers to make accurate predictions or inferences about the population based on the sample data.
A person or object that is a member of the population being studied is referred to as a "subject" or "unit of analysis." In research, this can include individuals, groups, organizations, or specific items that share common characteristics relevant to the study's objectives. For example, in a study examining the health of teenagers, each teenager surveyed would be considered a subject of the population. Identifying these subjects is crucial for gathering data and drawing valid conclusions about the entire population.

To define a population, you must identify the individuals or elements being studied, the characteristics or attributes that define them, the boundaries that determine who is included, and the purpose or reason for studying this group. These components help in clearly delineating the group under investigation.
The entire group being studied is referred to as the "population." This population includes all individuals or items that meet a specific set of criteria relevant to the research question. Researchers often select a sample from this population to gather data and draw conclusions, but the goal is to make inferences about the entire population based on the findings from the sample.
A specific group of individuals, such as a sample population, is typically studied in a scientific poll to gather data and insights on a particular topic or issue. This group is chosen to be representative of the larger population, allowing researchers to draw conclusions that can be generalized.

A relevant population refers to the group of individuals or subjects that the researcher is interested in studying and drawing conclusions about in a research study. It includes those individuals who meet the criteria for participation in the study and whose characteristics are of interest to the researcher.
In social research, the universe refers to the entire group or population that the researcher is interested in studying. It includes all individuals or elements that possess the characteristics being studied and is the target of generalizations made based on research findings.
