Which of the following is true of convenience sampling? - Using convenience samples to develop constructs and scales can be risk
BigorU [14]

Answer:

Using convenience samples to develop constructs and scales can be risky.

Explanation:

Convenience sampling refers to the process of gathering information from a sample that is conveniently available to the researcher (family members, friends in social media). This is not a random sampling method because not all of the members have the same probability to be selected.

  • Using convenience samples to develop constructs and scales can be risky.

From the definition, we can say that using convenience samples to develop constructs and scales can be risky since <u>the information gathered by using this sampling does not necessarily represent the characteristics of the population (since it was not chosen at random).</u>

  • It is a time-consuming process when there are a large number of respondents.

This is not a time-consuming process but is actually easier to gather information this way rather than by other methods.

  • It is commonly used in the later stages of research.

This process is a gathering of information process and it takes place at early stages of the research

  • The representativeness of the sample can be measured because sampling error estimates are not calculated

As we said before, this is not a random sample and therefore it is not necessarily a representative sample.

  • It is commonly used to generalize results to the target population.

Although probably our sample shares some characteristics with our target population, this sampling is not used to generalize results to the target population.
