The lower left-hand corner shows some methods for statistical design of experiments (Protocol 5), which is used to plan new experiments and choose analyses for existing experiments. When those typical statistical analyses are inadequate, the graphs in the lower right-hand corner show some examples of advanced methods (Protocol 6). Moving to the right, the second table shows how a researcher might choose among basic statistical tests like t-tests and ANOVA (Protocol 2), correlations and regression (Protocol 3), or contingency tables and generalized linear models (Protocol 4).

Starting at the upper left, the first table describes how a researcher might choose an appropriate graph (Protocol 1). These concepts and more would be used to determine how a data set should be graphed, which statistical tests should be used to analyze the data and how that information might be used to plan better experiments in the future.įlow-chart illustrating general approaches to use of statistics in immunology. gender is male or female, a person’s disease status can be infected or uninfected). 68.3 inches, 154.8 lbs, 17.1 micrograms, …), and categorical variables, which have a finite list of discrete outcomes (e.g. age, height, weight, mass, concentration of specific compounds, …) that can be measured precisely in fractions of a unit (e.g. Another important concept is the difference between continuous variables (e.g.

dependent variables), which are typically the variables outside of our control or the variables most influenced by our experimental conditions. independent variables), which are typically variables we can control or variables we expect to influence an outcome, and response variables (i.e. One key idea is the distinction between predictor variables (i.e. 1) describes the organization of the statistical concepts presented here, starting with statistical graphs and branching out into different statistical tests and concepts for specific types of immunological data.
