Key Concepts

Random Number Generation

Random number generation is a technique used to produce numbers where each outcome is independent and uniformly distributed. In the context of sampling, assigning computer-generated random numbers to individuals helps ensure that each member of the population receives an equal chance of selection, thereby supporting the integrity of the sampling process.

Selection Bias

Selection bias refers to a systematic error that occurs when the sampling method results in a sample that is non-representative of the population. By using methods that ensure every member has an equal probability of inclusion, such as simple random sampling with proper random number generation, the risk of selection bias is minimized.

Simple Random Sampling

Simple random sampling is a method in which every individual in the population has an equal chance of being selected, and every possible subset of a given size is equally likely. This principle ensures that the sample accurately represents the population without systematic bias, making statistical inferences valid for the entire group.
