Detailed explanation-1: -Population refers to the entire group or set of individuals, objects, or events being studied, while a sample is a subset of the population that is used for analysis. Descriptive Statistics: Descriptive statistics can be used to analyze both populations and samples.

Detailed explanation-2: -Samples. A sample is a random selection of members of a population. It is a smaller group drawn from the population that has the characteristics of the entire population. The observations and conclusions made against the sample data are attributed to the population as a whole.

Detailed explanation-3: -A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females.

Detailed explanation-4: -A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from. The size of the sample is always less than the total size of the population. In research, a population doesn’t always refer to people.

Detailed explanation-5: -Sample = the selected elements (people or objects) chosen for participation in a study; people are referred to as subjects or participants. Sampling = the process of selecting a group of people, events, behaviors, or other elements with which to conduct a study.
