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.

Twins. There is some indication in medical litera-ture that doctors may have become more aggressive in inducing labor or doing preterm cesarean sections whena woman is carrying twins. Records at a large hospitalshow that, of the 43 sets of twins born in 1990, 20 weredelivered before the 37th week of pregnancy. In 2000, 26of 48 sets of twins were born preterm. Does this indicatean increase in the incidence of early births of twins? Testan appropriate hypothesis and state your conclusion.
You are the staff epidemiologist in a large school district of 100,000 pupils. Your school nurses have diagnosed a few kids with a sore throat of unknown etiology, thought to be a contagious infection. In the first week there was one new case (the first or ‘index’ case). In the second week (when the index case is still sick) there are new seven cases. What is the prevalence of this infection in the pupil population of your school district? What is the incidence?

QDOS-C Are there more children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban areas over states that are mostly rural? In the state of Pennsylvania, a fairly urban state, there are 245 eight year olds diagnosed with ASD out of 18,440 eight year olds evaluated. In the state of Utah, a fairly rural state, there are 45 eight year olds diagnosed with ASD out of 2,123 eight year olds evaluated ("Autism and developmental," 2008). Is there enough evidence to show that the proportion of children diagnosed with ASD in Pennsylvania is more than the proportion in Utah? Test at the 1% level.
