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.
| # of hours | chemistry | biology |
| 0 | 70 | 64 |
| 1 | 77 | 72 |
| 2 | 82 | 78 |
| 3 | 85 | 82 |
You are taking two courses this semester, biology and chemistry. You have quizzes coming up in both classes. The table below shows your grade on each quiz for different numbers of hours studying for each quiz. For instance, the second row implies that one hour of studying for Chemistry will generate an expected grade of 77 on Chemistry, whereas one hour of studying for Biology will generate an expected grade of 72 on Biology.
