Research Methodology MCQ

What is the purpose of sampling techniques in research?

• Sampling techniques aim to make the research process more complicated

• Sampling techniques are used to exclude certain groups from the study

• Sampling techniques are only used in qualitative research

• The purpose of sampling techniques in research is to select a representative sample from a larger population to draw conclusions and make generalizations about the population.

Which sampling technique involves selecting every nth individual from a list?

• Convenience sampling

• Cluster sampling

• Random sampling

• Systematic sampling

What is the main advantage of random sampling?

• Reduces bias and ensures representativeness

• Guarantees a diverse sample

• Saves time and resources

• Increases accuracy and precision

What is the difference between probability sampling and non-probability sampling?

• In probability sampling, samples are randomly selected with known probabilities, while in non-probability sampling, samples are not randomly selected and have unknown probabilities.

• Probability sampling is used in qualitative research, while non-probability sampling is used in quantitative research.

• Probability sampling guarantees representative samples, while non-probability sampling does not consider representation.

• Probability sampling involves guessing the outcome, while non-probability sampling uses precise calculations.

What is an experimental design?

• A plan or blueprint for conducting an experiment to test a hypothesis.

• A map of a city

• A list of grocery items

• A recipe for baking cookies

What is the difference between independent and dependent variables?

• Independent variables are constant; dependent variables are variable.

• Independent variables are manipulated; dependent variables are measured.

• Independent variables are qualitative; dependent variables are quantitative.

• Independent variables are fixed; dependent variables are flexible.

What is a control group in an experiment?

• A control group is the group that receives the treatment in an experiment.

• A control group in an experiment is a group that does not receive the treatment being tested.

• A control group is a group that is excluded from the experiment entirely.

• A control group is a group that receives a different treatment than the experimental group.

What is the purpose of blinding in an experiment?

• To enhance the visibility of the results

• To introduce bias intentionally

• To speed up the experiment process

• To prevent bias and ensure the results are not influenced by preconceived notions or expectations.

What are the different types of data collection methods?

• Focus Groups

• Case Studies

• Literature Review

• Surveys, Interviews, Observations, Experiments, Existing Data Analysis

When is qualitative data collection method preferred over quantitative data collection method?

• When the research aims to quantify numerical data accurately

• When the research aims to explore complex phenomena, understand social processes, or gain in-depth insights into individual experiences.

• When the study requires statistical analysis for hypothesis testing

• When the researcher wants to generalize findings to a larger population
