    First, you need to understand the difference between a population and a sample, and identify the target population of your research. 1. The populationis the entire group that you want to draw conclusions about. 2. The sampleis the specific group of individuals that you will collect data from. The population can be defined in terms of geographical l...

    Probability sampling means that every member of the population has a chance of being selected. It is mainly used in quantitative research. If you want to produce results that are representative of the whole population, probability sampling techniques are the most valid choice. There are four main types of probability sample.

    In a non-probability sample, individuals are selected based on non-random criteria, and not every individual has a chance of being included. This type of sample is easier and cheaper to access, but it has a higher risk of sampling bias. That means the inferences you can make about the population are weaker than with probability samples, and your co...
