Probability samples are the only types of samples that allow valid statistical inferences from a sample to a population. This is because probability samples are selected using randomization, which ensures that each element in the population has an equal chance of being selected for the sample. This means that the sample is likely to be representative of the population, which allows for generalization of results to the population. A judgment sample is one in which the researcher uses their own judgment to select participants, which can introduce bias into the sample. A quota sample is one in which the researcher selects participants based on specific quotas (e.g., 50% men, 50% women), which can also introduce bias. A convenience sample is one in which participants are selected based on their availability or willingness to participate, which can also introduce bias.
