OTA 235: How to Find Qualitative and Quantitative studies

Archival Research

A research applies their own analytical model to data that has already been collected. They attempt to answer a new question or discover a new trend by looking at data.

Typical sources of archival data include census data, court records, medical records, and even case files.

Questionnaires

Participants are asked a standard set of questions. These questions may be delivered in writing or through an interview format.

There are three main types of questionnaire methods: random sampling, stratified sampling, and convenience sampling. 

Applied and Field Research

When using applied research, researchers are trying to find a solution to an immediate, practical problem.

Examples include reducing drug use or improving worker happiness.

Field research is a type of applied research that is undertaken in a non-laboratory setting. These settings may include a hospital or workplace.

Experimental Research

Research conducted in a controlled environment. These students help scholars in the field to learn more about psychological processes such as cognition or emotional development.
