Number of study sessions Total Enrollment Morning class 25 16 Night class 20 22 If the total study sessions for the night class were proportional to the morning class, how many would you expect the night class to have? How does this compare to the actual amount of study session the night class has?
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.
| Number of study sessions | Total Enrollment | |
| Morning class | 25 | 16 |
| Night class | 20 | 22 |
If the total study sessions for the night class were proportional to the morning class, how many would you expect the night class to have? How does this compare to the actual amount of study session the night class has?
If the night class were proportional to the morning class, we would expect them to have 26 more than the number of study sessions they have currently.
