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.
Probability could be defined as a number that always falls between 0 and 1, where 0 implies the impossibility of an event to happen and 1 implies the possibility of an event to happen. It could be defined as the number of favorable outcomes divided by the number of possible outcomes, where the outcomes are equally likely.
For a valid probability distribution, following conditions are necessary to be fulfilled:
- Sum of all the provided probabilities should be 1.
- The range of all the probabilities should always lie between 0 and 1.
