known to be selected


equal chance to be selected


Sampling frame not available


Strictly base on inclusion and exclusion criteria

Detailed explanation1: Social researchers speak more commonly of probability sampling, meaning that every member of a population being sampled has a known, nonzero chance of being selected into the sample. Usually, the probability of selection is also less than 100%, so random selection methods become involved.
Detailed explanation2: Simple random sampling. In simple random sampling (SRS), each sampling unit of a population has an equal chance of being included in the sample. Consequently, each possible sample also has an equal chance of being selected. To select a simple random sample, you need to list all of the units in the survey population.
Detailed explanation3: Definition: Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
Detailed explanation4: Simple random sampling gathers a random selection from the entire population, where each unit has an equal chance of selection. This is the most common way to select a random sample.
Detailed explanation5: Simple random sampling, stratified sampling, cluster sampling, and systematic sampling are all types of probability sampling.
