A new drug was developed to replace the existing molecule that cause severe side effects if frequently used. We screen number of patients and check four symptoms and prepare the following table that numbers indicate the total patient counts who used old and new medicine. Headache Dizziness Fewer Old drug 100 50 60 New drug 70 20 40 Using the data above, evaluate with significance test if new drug molecule has less side effects. (The significance level is 0.05)

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.
