Legend: red = textbook notes blue = slide notes green = lecture/discussion notes. The rate of new cases of the disease or condition of interest. It is generally reported within a period of time (e. g, a year) as a fraction of the population who are at risk of developing the condition. An estimate of the proportion of a population who already have (or have had) a disease/condition in a given time period. Sometimes prevalence is also reported as a fraction of the population. A statistical measure of the extent to which two or more variables are related. Correlations can be positive, in which case the variables increase or decrease in parallel. They can also be negative, such that when one (or more) variables increase, the other(s) decrease. Note that correlations speak to relationships among variables in a non-causal manner; correlations do not imply that one variable causes another.
