AP PSYCHOLOGY

Detailed explanation-1: -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-2: -What is probability sampling? Probability sampling means that every member of the target population has a known chance of being included in the sample. Probability sampling methods include simple random sampling, systematic sampling, stratified sampling, and cluster sampling.

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

Detailed explanation-4: -Key Takeaways. 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-5: -A simple random sample takes a small, random portion of the entire population to represent the entire data set, where each member has an equal probability of being chosen. Researchers can create a simple random sample using methods like lotteries or random draws.
