The primary characteristic of a probability sample is random selection of the sample, meaning every member of the population has an equal chance of being selected for the sample. This ensures that the sample is representative of the larger population, and allows for statistically valid generalizations to be made about the population based on the sample data. Self-selection or handpicking participants can introduce bias into the sample, making it less likely to be representative of the population. Representation of proportional segments of the population is a related concept, but is a consequence rather than a primary characteristic of using probability sampling methods.
