Explain how a sequential mixed-methods research design combines qualitative and quantitative methods to generate and test hypotheses. In your explanation, describe the specific role of each method (qualitative and quantitative) and how they connect to one another in this research process.
Question: Explain how a sequential mixed-methods research design combines qualitative and quantitative methods to generate and test hypotheses. In your explanation, describe the specific role of each method (qualitative and quantitative) and how they connect to one another in this research process.
Sample answer: In a sequential mixed-methods design, researchers first conduct a qualitative study to explore a phenomenon and gather rich, detailed data. This qualitative phase helps uncover why or how a phenomenon occurs, which allows the researcher to generate a specific hypothesis. After the hypothesis is generated, the researcher conducts a quantitative study to test it. In this second phase, the researcher operationally defines the variables, gathers data from a large sample, and uses statistical analyses to determine if the hypothesis is supported. The sequential transition connects the two phases because the qualitative findings directly inform the specific variables and hypotheses tested in the quantitative phase.
Key points:
- Qualitative research is used first to explore the phenomenon and generate hypotheses.
- Quantitative research is used second to test the newly generated hypothesis.
- The qualitative study gathers rich, detailed data to uncover why a phenomenon occurs.
- The quantitative study measures specific variables across a large sample to rigorously test the hypothesis.
- The transition is sequential, with the qualitative findings directly informing the quantitative phase.
Rubric: To earn full credit, the response must: 1) Identify that qualitative research is used first to generate hypotheses from rich, detailed data. 2) Identify that quantitative research is used second to test these hypotheses across a larger sample. 3) Explain the connection between the two phases, noting that the qualitative findings guide the definition of variables or formulation of the hypothesis tested in the quantitative phase.

A psychology research team first conducts in-depth focus groups to understand why college students experience test anxiety. Based on those discussions, they develop a theory, and then administer a standardized questionnaire to 1,000 students to statistically evaluate their theory. This scenario demonstrates using qualitative research for hypothesis generation and quantitative research for hypothesis testing.
