What is non-probability sampling?<\/h2>\n

Non-probability sampling is a technique used in the statistical sample, <\/strong>that unlike the probabilistic sample, it does not allow all individuals in a population to be investigated, have the same selection opportunities. <\/strong><\/p>\n

In this type of sampling, those individuals who, by fulfilling a certain quality or characteristic, benefit the research.<\/strong><\/p>\n

Non-probability sampling types<\/h2>\n

Non-probability sampling can be classified into m<\/strong>Quota, Convenience, Snowball, or Discretionary Sampling<\/strong>.<\/p>\n

\"Non-probability<\/p>\n

Non-probability sampling types.<\/p>\n<\/div>\n

Convenience sampling<\/h3>\n

Non-probability sampling for convenience is one where the researcher performs the sample, selecting individuals you consider accessible and quick to research<\/strong>. This, generally, he does by proximity to himself.<\/p>\n

For example:<\/strong> a researcher decides to carry out a study on the opinion of a teacher in a given classroom. Using convenience sampling, you make up your sample with the first 5 students on the classroom list.<\/p>\n

Quota sampling<\/h3>\n

Through quota sampling, the researcher ensures that the sample is fair and proportional<\/strong>, according to the characteristics, qualities or traits of the population to be studied.<\/p>\n

For example<\/strong>: a researcher must carry out a sample on the employees of a company, in which 60% are women and 40% are men. To do so, select individuals who are proportional to the population, through convenience sampling or the researcher's choice.<\/p>\n

Snowball sampling<\/h3>\n

Also known as chain sampling, this method consists of the researcher requires, from the first subject in the sample, to identify or designate another person who meets the research requirements<\/strong>.<\/p>\n

For example:<\/strong> a researcher decides to carry out an investigation whose sample is made up of individuals with a rare disease. In this way, when finding an individual with these characteristics, the researcher asks for help to find other people with these conditions to make up the sample.<\/p>\n

Discretionary sampling<\/h3>\n

Also know as judgment or intentional sampling<\/strong>, through this technique the subjects are chosen to c<\/strong>form a specific group<\/strong>, of people who are more suitable for analysis than others<\/strong>.<\/p>\n

For example:<\/strong> You want to conduct research on the behavior of parents with their children. Therefore, the researcher selects as a sample people who have children, since he considers them suitable for knowledge to be part of the research.<\/p>\n

Advantages and disadvantages of non-probability sampling<\/h2>\n

Advantage<\/h3>\n

The main advantages of non-probability sampling are as follows:<\/p>\n

    \n
  • Lower costs<\/strong> to conduct the investigation.<\/li>\n
  • They can control<\/strong> the characteristics of the sample.<\/li>\n
  • Carries less time<\/strong>, since the individual who will be part of the sample is known.<\/li>\n
  • They can be known unusual features.<\/strong><\/li>\n<\/ul>\n

    Disadvantages<\/h3>\n

    The main disadvantages of non-probability sampling are as follows:<\/p>\n

      \n
    • It does not ensure full representation of the population.<\/strong><\/li>\n
    • It does not generalize and it is subjective.<\/strong><\/li>\n
    • It is not recommended in the case that the investigation is causal or descriptive.<\/li>\n<\/ul>\n

      Examples of non-probability sampling<\/h2>\n

      Next we propose Some examples<\/strong> To understand the non-probability sample more clearly:<\/p>\n

        \n
      • A teacher wishes analyze the number of students with realistic goals,<\/strong> so he uses known volunteers and sends the survey back to the school, for those students to act as a sample.<\/li>\n
      • A social researcher chooses 50 unemployed people<\/strong> in a population and asks 5 of these to find another 10 unemployed people, to finish the analysis and research using the snowball method.<\/li>\n<\/ul>\n<\/div>\n\n\n
