AP PSYCHOLOGY

Detailed explanation-1: -In a clustered sample, subgroups of the population are used as the sampling unit, rather than individuals. The population is divided into subgroups, known as clusters, which are randomly selected to be included in the study.

Detailed explanation-2: -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: -Cluster sampling divides your population into groups and a simple random selection of those groups is made. You then survey everybody within the selected groups.

Detailed explanation-4: -In statistics, a sample group can be defined as a subset of a population. The population, or target population, is the total population about which information is required.

Detailed explanation-5: -A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from. The size of the sample is always less than the total size of the population. In research, a population doesn’t always refer to people.
