Suppose that we have two attributes, gender and department. We observe the values of both variables in a random sample of 100 students. IT Business Male 33 9 Female 34 24 A student is selected, find the probability that the Selected student is female and from Business. Selected student is from IT. Selected student is male or from IT.
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.
