Which sequence best matches the four basic research types described: exploratory, descriptive, explanatory, and evaluation?

Which sequence best matches the four basic research types described: exploratory, descriptive, explanatory, and evaluation?

• A. Exploratory describes, Descriptive explains, Explanatory evaluates
• B. Exploratory evaluates, Descriptive describes, Explanatory explains
• C. Exploratory describes, Descriptive describes in more detail, Explanatory explains relationships, Evaluation uses data to modify a program
• D. Exploratory explains, Descriptive evaluates, Explanatory describes

Answer: (C)

The main idea this item tests is how the four basic research types align with their typical roles in research. Exploratory work aims to uncover issues and generate questions. Descriptive work centers on detailing characteristics of a population or situation. Explanatory work seeks to explain relationships between variables, often addressing causality. Evaluation uses data to judge a program or intervention and, based on findings, modify or improve it. The best match presents a logical sequence: exploratory describes, descriptive describes in more detail, explanatory explains relationships, and evaluation uses data to modify a program. This reflects moving from discovery to a richer description, to understanding how things relate, and finally to applying findings to improve practice. Other sequences misplace these functions. For example, pairing exploratory with evaluation or having descriptive take on an evaluative role contradicts what each type is expected to do, and assigning explanatory to describe (instead of explain relationships) or to evaluate also mismatches the intended purpose.
