Detailed explanation-1: -This can be done in one of two ways: the lottery or random number method. In the lottery method, you choose the sample at random by “drawing from a hat” or by using a computer program that will simulate the same action. In the random number method, you assign every individual a number.
Detailed explanation-2: -Sampling is the process of selecting a representative group from the population under study. The target population is the total group of individuals from which the sample might be drawn. A sample is the group of people who take part in the investigation.
Detailed explanation-3: -Simple random sampling. In simple random sampling (SRS), each sampling unit of a population has an equal chance of being included in the sample. Consequently, each possible sample also has an equal chance of being selected.
Detailed explanation-4: -If you want to produce results that are representative of the whole population, probability sampling techniques are the most valid choice.
