An Example of Judgment Sampling A group of researchers is interested in learning if the reason why people wear eyeglasses is to read books. Common sense tells us that the efforts of the research group should be focused entirely on people that indeed wear eyeglasses. This process is judgment sampling in action.
In simple random sampling, a probability sampling technique, individuals in a larger population each have a fair and equal chance of being selected for a smaller sample. Convenience sampling relies on location and accessibility to determine the research variables. This makes it very difficult to replicate results.
A sample is a subset of individuals from a larger population. Sampling means selecting the group that you will actually collect data from in your research. For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.
The main difference between stratified random sampling (judgment sampling) and random sampling is that with the former the sample frames are constructed around a specific group of people. First, the researcher must stratify the sample ing to the categories which are relevant to the project.
Convenience sampling attempts to obtain a sample of convenient elements. Often, respondents are selected because they happen to be in the right place at the right time. Judgmental sampling is a form of convenience sampling in which the population elements are selected based on the judgment of the researcher.

For example, a store determines its customer base of 1000 is comprised of 600 women and 400 men. Sample based on proportion. The quota size should be representative of the collective subgroup population. In the example above, he should select 60 women and 40 men.
Convenience sampling is a non-probability sampling method where units are selected for inclusion in the sample because they are the easiest for the researcher to access. This can be due to geographical proximity, availability at a given time, or willingness to participate in the research.
The process of selecting a sample using judgmental sampling involves selecting items based on specific criteria, such as gender, educational level, age, socioeconomic status, or any other factor relevant to research by experts.
An expert with knowledge of the population decides which units in the population should be sampled. In other words, the expert purposely selects what is considered to be a representative sample. Judgment sampling is subject to the researcher's biases and is perhaps even more biased than haphazard sampling.
