Question

Definition of simple random sampling and its example

Answer 1

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group. An example of a simple random sample would be the names of 25 employees being chosen out of a hat from a company of 250 employees. In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.

Answer 2

A randomly selected sample from a larger sample or population, giving all the individuals in the sample an equal chanceto be chosen. In a simple random sample, individuals are chosen at random and not more than once to prevent a bias that would negatively affect the validity of the result of the experiment.

Example: Simple random sample would be the names of 25 employees being chosen out of a hat from a company of 250 employees.
