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.

Activity: Tossing 5 coins
Conduct a small experiment on probability distribution by tossing 5 coins. Perform the
experiment by tossing 5 coins 20 times. Observe the number of heads that will occur. The
possible values of X or the number of heads in 5 coin tosses are 0,1,2,3,4, and 5. Keep track
of the number of times each outcome occurred and complete the table below.
