AP PSYCHOLOGY

Detailed explanation-1: -A simple random sample is one of the methods researchers use to choose a sample from a larger population. This method works if there is an equal chance that any of the subjects in a population will be chosen. Researchers choose simple random sampling to make generalizations about a population.

Detailed explanation-2: -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. To select a simple random sample, you need to list all of the units in the survey population.

Detailed explanation-3: -There are four primary, random (probability) sampling methods – simple random sampling, systematic sampling, stratified sampling, and cluster sampling.

Detailed explanation-4: -This method gives every member of the target group an equal chance of being selected for the sample (e.g. by assigning a number to each member, and then selecting from the pool at using a random number generator).
