A postpositivist researcher “fails to reject” rather than proves hypotheses because:

A researcher collects survey data measuring student satisfaction and conducts interviews with students during the same time period. The researcher then compares and integrates both sets of results to develop a more complete understanding. Which mixed methods design is this?

A researcher analyzes interview transcripts from 20 first-generation students. The researcher’s initial codes include: “navigating multiple identities,” “experiencing discrimination,” “managing financial stress,” “uncertain belonging,” “seeking support,” “family expectations,” “demonstrating resilience.” After two coding rounds, these organize into three themes: Identity Negotiation: Students actively reconciling multiple identities (first-gen, racial/ethnic, socioeconomic, academic) in tension with institutional cultures Institutional Barriers and Agency: Students encountering systemic obstacles while exercising strategic agency and adaptation Relational Anchors: Specific individuals providing emotional, informational, or practical support The researcher reflects: “As a first-generation student myself, I notice I coded ‘resilience’ frequently. I wonder if I’m over-interpreting students’ adaptive responses as strength rather than considering them as necessary survival strategies in an unsupportive system. My own positive narrative about overcoming disadvantage may be shaping how I interpret student experiences.” This researcher is primarily demonstrating:

A researcher creates a survey to measure academic motivation, but the items focus only on attendance and homework completion and do not assess students’ interest, goals, or effort. Which type of validity is most threatened?

A researcher believes reality exists independently but can only be imperfectly measured. This reflects:
