Detailed explanation-1: -Probability sampling means that every member of the population has a chance of being selected. It is mainly used in quantitative research. If you want to produce results that are representative of the whole population, probability sampling techniques are the most valid choice.

Detailed explanation-2: -The target population of a study is the broad group of people that researchers are examining. In clinical trials, this means the group of people researchers think might benefit from a particular experimental drug.

Detailed explanation-3: -The target population is essential for three primary reasons: Sets clear direction on the scope and objective of the research and data types. Defines the characteristic variables of the individuals who qualify for the study. Provides the scope of the total population or universe for determining sample size.

Detailed explanation-4: -Your sample will need to contain individuals who resemble the whole population by including all demographic groups (gender, rural, urban, income levels, etc.) and have them in the same proportions as the whole population. For example, it’s not truly representative if you have too many rural participants, or males, etc.
