Research Sampling Quiz- W2

What is the primary purpose of using a sample in research?

• To eliminate variables

• To avoid using any data

• To represent a larger population

• To validate qualitative data

Which of the following is NOT a reason for selecting a relevant sample type?

• Representativeness

• Generalizability

• Convenience for the researcher

• Bias introduction

Which term describes the group of people the researcher wants to draw conclusions about?

• Sample frame

• Control group

• Target population

• Independent variable

An appropriate sample type helps to:

• Reduce ethical responsibilities

• Increase data collection time

• Improve research efficiency

• Eliminate all bias

A biased sample can result in:

• Accurate generalizations

• Misleading findings

• High representativeness

• Improved validity

Generalizability in research means:

• Applying findings to the sampled group only

• Drawing conclusions without statistics

• Applying results to the whole population

• Ensuring all samples are equal

Sampling is particularly useful when:

• The population is small and accessible

• Testing the entire population is impossible

• Data collection is not required

• Researchers prefer not to analyse data

One ethical concern in sampling is:

• Lack of data analysis tools

• Over-recruiting volunteers

• Subjecting participants to unnecessary risks

• Too much data collection

Which of the following contributes to sampling bias?

• Using a random number generator

• Sampling only from a specific location

• Including all strata in sampling

• Using multistage sampling

A good sample must:

• Include as many participants as possible

• Be identical to the population

• Be representative and relevant

• Contain every demographic group
