The sampling method, also known as the sampling methodology, is the act of examining a population by acquiring data and evaluating it. It's the data's basis, and the sample space is huge.
There are a few different sampling procedures to choose from, and they may be classified into two categories. All of these sampling methods may include deliberately targeting hard-to-reach or difficult-to-reach populations.
Types of Sampling Method
There are a variety of sampling approaches accessible in statistics to obtain relevant data from a population. The following are the two types of sampling methods:
The probability sampling approach employs some form of random selection. Using this method, all of the eligible participants have an equal opportunity to choose a sample from the whole sample of candidates. The non-probability sampling method takes longer and makes it more expensive. Because it ensures that the sample will be representative of the population, probability sampling is a good method to use.
Types of Probability Sampling
Simple random sampling
In the non-probability sampling method, the sample is chosen by the researcher based on his or her own subjective assessment, rather than using a random selection technique. Because of the limitations of this method, not every person in the population can be included in the research.
Types of Non-probability Sampling
Purposive or Judgmental sampling
Following are some of the multiple choice questions on the Sampling Methods with answers that will help the students in developing their knowledge.
