In a hypothetical city, there is a population of 200,000 people. During the year 2000, there were 1,000 deaths from all causes. All new cases of disease “X” have been accounted for and they total 600 (400 male
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.
In a hypothetical city, there is a population of 200,000 people. During the year 2000, there were 1,000 deaths from all causes. All new cases of disease “X” have been accounted for and they total 600 (400 males and 200 females). During the year 2000 there were 120 deaths from disease “X”, 100 of them in males.
- Assume the number of existing cases of disease “X” at the end of 1999 is 1200. What is the prevalence rate of disease “X” per 100,000 population at the end of the year 2000?
