1. In January 2010 you began a one-year study of malaria in a subsidized housing community in Malabon City. You enrolled 500 residents in your study and checked on their malaria status on a monthly basis. At the start of the study, you found that 10 of the residents were positive for malaria and 20 residents were actually vaccinated immigrants. Another 30 residents screened positive for malaria in the months ahead. As an epidemiologist, you want to know the following (expressed in 2 decimal places and per X population when applicable): A. What is the point prevalence of malaria in the screened community on January 1st? B. What is the period prevalence of malaria in this community in the year 2000? C. What is the cumulative incidence for the one year period?
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.
