Data Collection & Sampling Quiz

What is random sampling?

• A method of selecting a sample based on personal preference

• Choosing a sample that only includes the most extreme cases

• Selecting a sample where the researcher intentionally picks certain individuals

• A method of selecting a sample from a larger population where each member of the population has an equal chance of being selected.

Explain the process of selecting a random sample.

• Picking individuals who are willing to participate in the study

• Choosing individuals based on personal bias

• Ensuring that every member of the population has an equal chance of being chosen

• Selecting only the most easily accessible members of the population

What are the advantages of using random sampling?

• Increases bias and ensures non-representativeness

• Reduces bias and ensures non-representativeness

• Increases bias and ensures representativeness

• Reduces bias and ensures representativeness

What are the disadvantages of using random sampling?

• Random sampling may lead to biased results.

• Random sampling is not suitable for large populations.

• Random sampling always provides accurate results.

• Random sampling is time-consuming and expensive.

What is convenience sampling?

• A sampling technique that ensures every member of the population has an equal chance of being selected

• A sampling technique that involves selecting every nth individual from the population

• A non-probability sampling technique where subjects are selected based on their convenient accessibility and proximity to the researcher.

• A sampling technique that involves selecting individuals who are most similar to the researcher

Give an example of convenience sampling.

• Interviewing students who are waiting in line to buy tickets for a concert.

• Asking people in a shopping mall to participate in a survey.

• Asking people in a hospital waiting room to participate in a survey.

• Surveying only the first 10 people who enter a grocery store.

What are the limitations of convenience sampling?

• Reduces bias in the sample

• Allows for diverse representation

• Guarantees accurate results

• Limited representation of the entire population

What is data collection?

• Guessing and estimating information on targeted variables

• Storing and organizing information on targeted variables

• Ignoring and discarding information on targeted variables

• Gathering and measuring information on targeted variables

Explain the importance of accurate data collection.

• Accurate data collection ensures reliable information for informed decisions.

• Accurate data collection ensures unreliable information for uninformed decisions.

• Accurate data collection is not important and can lead to biased information.

• Accurate data collection is only important for unimportant decisions.

What are the different methods of data collection?

• Surveys, interviews, observations, and experiments

• Questionnaires, focus groups, case studies, and surveys

• Interviews, reviews, questionnaires, and focus groups

• Examinations, reviews, questionnaires, and case studies
