Principal investigator The individual who is primarily responsible for a research study. The principal investigator is responsible for all elements of the study and is the first author listed on publications or presentations.

Purposeful selection A technique used in qualitative research in which the subjects are selected because they possess certain characteristics that enhance the credibility of the study.

Qualitative research A naturalistic approach to research in which the focus is on understanding the meaning of an experience from the individual’s perspective. Quality improvement The systematic, data-based monitoring and evaluation of organizational processes with the end goal of continuous improvement. The goal of data collection is internal application rather than external generalization. Quantitative research A traditional approach to research in which variables are identified and measured in a reliable and valid way.
Quasi-experimental designs Studies of cause and effect similar to experimental designs but using convenience samples or existing groups to test interventions.
