AP Research · Unit 3: Method & Data Collection

3.1 Choosing a Method

Match method to question

Your method must fit your question. Quantitative methods measure and count (surveys, experiments, statistics); qualitative methods explore meaning (interviews, observation, text analysis).

Mixed methods

Mixed methods combine both — for example, a survey (quantitative) plus interviews (qualitative) — to get numbers and depth together.

Common designs

Designs include experiments (manipulate a variable), correlational studies (measure relationships), case studies, content analysis, and ethnography. Each answers different kinds of questions.
