DSRT 734: Designing a Research Question, Data Plan, and Statistical Test

DSRT 734 Question

You have completed the DSRT 734 course. It is time to apply your
learning. Respond to each of the following areas:

Design a research question relevant to your specialty area.

Describe what type of data you would gather to answer the research
question.

Determine which statistical test would be best to answer your research
question.

What would you determine if the results were significant, based on
your research question?

What this question assesses

This open-ended assignment assesses alignment across a research problem, analyzable question, data structure, statistical method, and interpretation. It also tests whether a statistically significant result is described within the limits of the chosen design.

How to approach this type of question

Create an original plan in five linked passes. First define a bounded specialty-area problem, a target population, and a question that names the variables or group contrast without presupposing the result. Second make a variable table: operational definition, measurement scale, unit, expected range, and role as outcome, predictor, group, or control. Third describe the sampling unit, sampling strategy, timing, and whether observations are independent, paired, repeated, or clustered. Address consent, privacy, missingness, and feasible sample size without inventing data. Fourth map the design to a method family by asking whether the goal is a mean comparison, categorical association, correlation, regression, or another justified analysis. List assumptions and the diagnostic evidence that would be checked before naming a final method. Fifth plan the interpretation: define the null and alternative hypotheses, the statistic and uncertainty to report, and the practical quantity that would matter in the specialty. A significant result would mean the observed evidence is inconsistent with the null under the model and threshold; it would not automatically establish causality, importance, replication, or a guaranteed decision outcome. Finish with a limitations checklist covering representativeness, measurement quality, confounding, multiplicity, and generalizability. The student must supply the specialty context and final research design.

Before writing, test alignment by reading the plan as a chain: population and question lead to variables; variables and sampling lead to a design; design and assumptions lead to a method; method and output lead to a bounded conclusion. If any link cannot be explained, revise the preceding decision rather than adding statistical vocabulary. Include a data dictionary and an analysis decision table in planning notes, even if they do not appear in the final submission. Predefine the outcome, comparison, alpha, exclusions, and handling of missing data when feasible to reduce result-driven choices. Consider whether repeated observations, organizational clustering, or multiple outcomes require a more complex model than a simple test. State what effect size or interval would make the result useful for the specialty, and distinguish that from merely crossing a p-value threshold. Finally, describe what would be concluded if evidence is not significant without saying there is no effect. This framework preserves the student’s responsibility to supply a real specialty question and reasoned final design.
