Answer

Brief Explanations:

  • For the first question, descriptive research systematically observes and describes a person, group, or behavior patterns. It doesn't establish cause - and - effect (experimental research does that), nor does it tell about variable relationships like correlational research, and conditions aren't created as in experiments.
  • For the second question, Felix is doing an in - depth study of a single adolescent, using multiple data sources like records and interviews, which is characteristic of a case study.
  • For the third question, a sample is a subset of a population, so a population includes a sample.

Answer:

  • Question 29: C. It is designed to systematically investigate a person, group, or patterns of behavior.
  • Question 30: B. case study
  • Question 31: A. a population includes a sample
