All members of the target population have an equal chance of being selected.

Detailed explanation-1: -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-2: -A simple random sample is a randomly selected subset of a population. In this sampling method, each member of the population has an exactly equal chance of being selected.
Detailed explanation-3: -Random selection refers to how sample members (study participants) are selected from the population for inclusion in the study. Random assignment is an aspect of experimental design in which study participants are assigned to the treatment or control group using a random procedure.
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 representative sample is a small subset group that seeks to proportionally reflect specified characteristics exemplified in a target population.
