“Quasi-Statistical” is a somewhat loose term that could refer to:

- Quasi-experiments
- Becker’s Quasi-statistics

## 1. Quasi-Experimental Design

A quasi-experimental design is missing one or more key components of a solid experimental design, which are:

- Pre-post test design.
- Treatment and control groups.
- Random assignment of subjects to groups.

For more information on this type of quasi-statistical analysis, see: Quasi-Experimental Design.

## 2. Becker’s Quasi-Statistics

Becker’s quasi-statistics are a way to make non-precise counts (like “some,” “usually,” or “most”) more precise. The counts are obtained from qualitative research, and can be thought of as a type of numerical data within a qualitative framework. It is used as a strategy for assessing internal generalization; Internal generalizability is extending results to participants or other experimental components within the setting/case/institution that weren’t directly observed (Maxwell & Chmiel, 2014).

Becker states that “One of the greatest faults in most observational case studies has been their failure to make explicit the quasi-statistical basis of their conclusions” (1970: 81–2). However, it should be noted that the term “quasi-statistics” can be misleading; quantifying vague terms like “usually” or “most” doesn’t turn a qualitative analysis into a quantitative one. “Using numbers in this way is not “statistical,” and does not make a study “quantitative” in the usual meaning of this term (Maxwell, 2010); it simply makes it explicit, and more precise (Maxwell & Chmiel, 2014, p. 10).” Although it’s possible to run hypothesis tests with quasi-statistical data obtained in this way, care should be taken when reading results because technically, they aren’t “statistical” in the usual sense of the term.
