Key Concepts

Simple Random Sampling

Simple random sampling is a method in statistics where each member of a population has an equal chance of being selected for the sample. This method helps ensure that the sample is unbiased and representative of the population, as the selection process is based solely on chance.

Population and Sample

In statistics, the population refers to the entire set of items or subjects being studied, while the sample is a subset of the population chosen for analysis. Drawing a sample correctly allows for inferences about the entire population based on the characteristics observed in the sample.

Randomization Process

The randomization process involves using a mechanism—such as a random number generator or drawing lots—to ensure that every member of the population has an equal opportunity to be selected. This minimizes bias and ensures the validity of statistical tests and conclusions drawn from the sample.
