Non-Probability Sampling. every 100th name in the yellow pages ! This can be accomplished by using randomized statistical sampling techniques or probability sampling like cluster sampling and stratified sampling. This type of sampling is also known as non-random sampling. The sample obtained from the population must be representative of the same population. This is the primary concern in statistical sampling. Overview. Simple Random Sampling: Every member of the population is equally likely to be selected) ! There are four main types of probability sample. It is mainly used in quantitative research. Probability sampling means that every member of the population has a chance of being selected. It does not rely on randomization. A sample is a group of units selected from a larger group (the population). From the food you eat to the television you watch, from political elections to school board actions, much of your life is regulated by the results of sample surveys. This technique is more reliant on the researcher’s ability to select elements for a sample. Sampling is a popular statistical concept – learn how it works in this article; We will also talk about eight different types of sampling techniques using plenty of examples Systematic Sampling: Simple Random Sampling in an ordered systematic way, e.g. If you want to produce results that are representative of the whole population, you need to use a probability sampling technique. Probability sampling methods. Sampling Methods used in Statistical Analysis . Concerns in Statistical Sampling Representativeness. Outcome of sampling might be biased and makes difficult for all the elements of population to be part of the sample equally. Stratified Sampling: Population divided into different groups from which we sample randomly ! Random sampling methods !
