Document Summary

If we had only measured absenteeism, that would be a univariate test. If we had measured more than one variable, that would be a multivariate test. Why are stats useful: statistics condense large amounts of information into a few simple figures or statements. If we use stats, one number can summarize thousands of data points and tell us if an intervention is working well: graphs are easy and quick to interpret, especially when we have lots of information to interpret. A set of mathematical procedures for organizing, summarizing, and interpreting information. In the world of stats, we should all know what a number means and the laws of stats. Where do our data come from: who/what are we interested in studying, data comes from objects (ex. Biomechanics studies golf balls, skis, clubs: population: all individuals (or objects) of interest in a particular study, problem: very often, we cannot test (ex.
