Examining Data: A General Strategy and One-Sample Methods (UMAP)

This module gives some general comments about an overall strategy for analyzing data. It discusses certain general considerations to keep in mind about the analysis, and it also discusses the order in which the statistical methods might be used. The general philosophy is to do the simpler techniques first and proceed to more complicated methods only if the simpler ones do not give clear and sufficient answers. There is a discussion of numerical and graphical methods for examining one set of measurements. Included are the median, mean, histogram, stem-and-leaf plot, cumulative distribution function, and a measure of variability.
