What is the ratio of deaths from gastroenteritis to heart disease in the total population, and in the 0-9 and 70-79 age groups respectively? What do you notice? What proportion of total deaths in the community is due to respiratory disease? What is the proportion due to heart disease?
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.
