Concept explainers

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

The Myers-Briggs Personality Type Inventory is a commonly used tool to indicate the core personality traits of individuals and are broken down into 4 components: How you interact with others (introvert or extravert); how you process information (sensing or intuitive); how you make decisions (thinking or feeling); and the structure you prefer to work in (judging or perceiving). The MBTI was administered to 375 couples to ask whether people tend to marry people with the same or different personality types.
