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 (hypothetical) table below showed the relationship between the number of hours students work at part-time jobs each week and the number of years it takes then to graduate with an undergraduate degree. If a student works more than 5 hours per week, what is the probability that the student graduates in over 6 years?
