Count - ANSWER-Simplest and most frequently performed quantitative measure in epidemiology. Refers to the number of cases of a disease or a health condition being studied. Ratio - ANSWER-Is the relative magnitude of two quantities or a comparison of two values. Often expressed as some number to 1. Not used as an estimate of risk. Calculated by dividing one variable by another. For example males to females in an outbreak: (number of females)/(number of males) gives a female to male ratio De...
