# Sampling Methods MCQ Commerce

50 Questions 30 Mins

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:

• Probability Sampling
• Non-probability Sampling

#### Probability Sampling

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
• Systematic sampling
• Stratified sampling
• Clustered sampling

#### Non-probability 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

• Convenience sampling
• Consecutive sampling
• Quota sampling
• Purposive or Judgmental sampling
• Snowball sampling

Following are some of the multiple choice questions on the Sampling Methods with answers that will help the students in developing their knowledge.
