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.

Do the different diets appear to affect the amount of iron present in the livers?
Twelve volunteers were assigned to each of three weight-reducing plans. The assignment
6.
of the volunteers to the plans was at random, and it was assumed that the 36 volunteers
in all would resemble a random sample of people who might try a weight-reducing
program. Test the null hypothesis that there is no difference in the probability distributions
of the amount of weight lost under the three programs against the alternative that there
is a difference. The results are given as the number of pounds lost by each
person.
