Research Design Quiz

In informatics research, a research design primarily refers to:

• The step-by-step coding process

• The framework that outlines how data will be collected, measured, and analyzed

• The user interface of a system

• The budget allocation for research

Which of the following is a quantitative research method in informatics?

• Case study

• Ethnography

• Survey using structured questionnaires

• Focus group discussion

The experimental research design is best suited for:

• Testing cause-and-effect relationships between variables

• Exploring user opinions without structured data

• Reviewing literature sources

• Designing graphical interfaces

A cross-sectional study in informatics involves:

• Collecting data from the same subjects repeatedly over time

• Collecting data at a single point in time

• Analyzing historical documents only

• Conducting experiments in different countries

Which of the following best describes mixed-methods research?

• Using only qualitative methods

• Using only quantitative methods

• Combining qualitative and quantitative methods in a single study

• Avoiding data analysis entirely

In research methodology, a pilot study is conducted to:

• Publish preliminary results

• Test the feasibility of the research design before the full study

• Replace the main study

• Avoid ethical review requirements

Which sampling technique ensures that every member of the population has an equal chance of selection?

• Stratified sampling

• Convenience sampling

• Simple random sampling

• Purposive sampling

In informatics, a dependent variable refers to:

• The variable that is manipulated by the researcher

• The variable that is measured to assess the effect of changes in another variable

• A variable that is constant throughout the study

• Any unrelated factor in the study

Which research design is most suitable for evaluating the usability of a new software application?

• Historical research

• Experimental design with user testing

• Cross-sectional survey of unrelated topics

• Content analysis of documents

The main purpose of a methodology section in an informatics research paper is to:

• Present all literature sources

• Describe how the research was conducted in detail so it can be replicated

• Summarize results and conclusions

• Advertise the research to funding agencies
