## Type of Sampling

Home QuestionPro Products Audience. Definition: Probability sampling is defined as a sampling technique in which the researcher chooses samples from a larger population using a method based on the theory of probability. Select your respondents. The most critical requirement of probability sampling is that everyone in your population has a known and equal chance of getting selected. For example, if you have a population of people, every person would have odds of 1 in for getting selected.

## Non-Probability Sampling: Definition, types, Examples, and advantages

Home QuestionPro Products Audience. Definition: Non-probability sampling is defined as a sampling technique in which the researcher selects samples based on the subjective judgment of the researcher rather than random selection. It is a less stringent method. This sampling method depends heavily on the expertise of the researchers. It is carried out by observation, and researchers use it widely for qualitative research.

Simple random sampling is a type of probability sampling technique [see our article, Probability sampling , if you do not know what probability sampling is]. With the simple random sample, there is an equal chance probability of selecting each unit from the population being studied when creating your sample [see our article, Sampling: The basics , if you are unsure about the terms unit , sample and population ]. This article a explains what simple random sampling is, b how to create a simple random sample, and c the advantages and disadvantages of simple random sampling. Imagine that a researcher wants to understand more about the career goals of students at a single university. Let's say that the university has roughly 10, students.

The goal of random sampling is simple. It helps researchers avoid an unconscious bias they may have that would be reflected in the data they are collecting. This advantage, however, is offset by the fact that random sampling prevents researchers from being able to use any prior information they may have collected. This means random sampling allows for unbiased estimates to be created, but at the cost of efficiency within the research process. Here are some of the additional advantages and disadvantages of random sampling that worth considering.

Simple random sampling occurs when a subset of a statistical population allows for each member of the demographic to have an equal opportunity of being chosen for surveys, polls, or research projects.
