What is Distributive Property
A sample of a population in which the number of subjects in the sample with the trait that you are studying is proportional to the number of members in the population with that trait; accurately represents the population and doesn’t have bias.
What is Representative Sample
A _________ consists of an action, its sample space, and a list of events with their probabilities. The events and probabilities in the list have these characteristics: each outcome in the sample space is in exactly one event and the sum of all the probabilities must be one.
