Research Design

What is the primary purpose of research design?

• To analyze data

• To ensure that the research question is clearly addressed

• To publish research findings

• To choose a research topic

Which type of research design focuses on establishing cause and effect relationships?

• Descriptive

• Experimental

• Correlational

• Narrative

What does a cross-sectional study involve?

• Studying the same subjects over a period of time

• Studying different subjects at one point in time

• Comparing results from different experimental conditions

• Creating longitudinal data analysis

Which of the following is a key feature of a longitudinal study?

• It can definitively establish causation

• It observes the same participants on multiple occasions over a period

• It typically concludes within a short period

• It is generally used to collect qualitative data

Which of these is an example of a qualitative research method?

• Surveys

• Experiments

• Interviews

• Randomized controlled trials

In the context of research design, what does "sampling" refer to?

• The process of selecting units of analysis for the study

• The choice of location for conducting experiments

• The technique for data analysis

• The publication of research findings

What distinguishes an observational study from an experimental study?

• Observational studies do not manipulate variables, whereas experimental studies do.

• Observational studies are quicker to conduct.

• Observational studies always use qualitative data, while experimental studies use quantitative data.

• Experimental studies cannot establish causality.

Identify the mixed method employed by Dr. Jensen based on the scenario.

• Dr. Jensen simultaneously collects quantitative data on student test scores and qualitative data from interviews with students and teachers about their experiences with the tool. She analyzes both datasets independently and then compares the results to draw conclusions.

• Convergent Parallel Design

• Sequential Embedded Design

• Exploratory Sequential Design

• Explanatory Sequential Design

Identify the mixed method employed by Dr. Jensen based on the scenario.

• Dr. Jensen prioritizes collecting qualitative data before the intervention, then she gathers quantitative data on student test scores. She then conducts qualitative data collection by interviewing selected students and teachers to provide context to the numbers during the analysis phase.

• Convergent Parallel Design

• Sequential Embedded Design

• Exploratory Sequential Design

• Explanatory Sequential Design

Identify the mixed method employed by Dr. Jensen based on the scenario.

• Dr. Jensen starts by conducting interviews with students and teachers to gather insights on their experiences and perceptions. Based on the qualitative findings, she designs a survey to quantitatively measure the broader impact of the educational tool on test scores.
