Investigators interested in the association between serum vitamin D levels and various birth outcomes recruited pregnant mothers to have a blood draw during the second trimester of their pregnancy. Mothers were followed until they gave birth. The health outcomes were compared among mothers with low, adequate, and high vitamin D levels. Describe a risk measurement that you think would be most appropriate to compare the groups, and justify your choice.
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.
