AP PSYCHOLOGY

Detailed explanation-1: -Sampling can be defined as the process through which individuals or sampling units are selected from the sample frame. The sampling strategy needs to be specified in advance, given that the sampling method may affect the sample size estimation.

Detailed explanation-2: -Convenience sampling is the term used when we select any participant who is readily available. When we choose easily available participants who fit a particular criterion, we are using quota sampling. Referral sampling involves including participants in the sample who have been referred by other participants.

Detailed explanation-3: -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. The people who take part are referred to as “participants”.

Detailed explanation-4: -Sampling can be done through probability (random selection) or non-probability (non-random) technique. Now, if the sampling frame is approximately the same as the target population, random selection may be used to select sample.

Detailed explanation-5: -Probability Sampling is a sampling technique in which samples from a larger population are chosen using a method based on the theory of probability. Non-probability sampling is a sampling technique in which the researcher selects samples based on the researcher’s subjective judgment rather than random selection.
