Answer 1

Descriptive (e.g., case-study, naturalistic observation, survey)


Correlational (e.g., case-control study, observational study)


Semi-experimental (e.g., field experiment, quasi-experiment)


Experimental (experiment with random assignment)


Review (literature review, systematic review)

Answer 2

A research design is the set of methods and procedures used in collecting and analysing measures of the variables specified in the research problem research. The design of a study defines the study type (descriptive, correlation, semi-experimental, experimental, review, meta-analytic) and sub-type (e.g., descriptive-longitudinal case study), research problem, hypotheses, independent and dependent variables, experimental design, and, if applicable, data collection methods and a statistical analysis plan.
