chi square
This term refers to a specific statistical distribution and the resulting test used to evaluate the independence of two categorical variables. It is primarily used in quantitative research to identify whether an observed pattern of data deviates significantly from what would be expected by chance.
In academic and professional writing, the term is often used as a modifier for other nouns, such as "chi square test" or "chi square distribution." While the term is derived from the Greek letter chi (χ) and the mathematical operation of squaring, it is treated as a single conceptual unit in statistical discourse.
Meanings
