Document Summary

Graphs for interval or ratio data (histograms and polygons) Graphs for nominal or ordinal data (bar graphs) Graphs for population distributions (relative frequencies and smooth curves) Comparing stem and leaf displays with frequency distributions. Learning objectives and chapter summary: students should understand the concept of a frequency distribution as an organized display showing where all of the individual scores are located on the scale of measurement. Note that one goal of descriptive statistics is to organize research results so that researchers can see what happened. If scores are presented in a regular table, students should be able to retrieve the complete list of original scores. The purpose for a grouped table is to keep the presentation relatively simple and easy to understand. All of the guidelines for constructing a grouped table are intended to help make the result easy and simple. Note, however, that after the scores have been put into a grouped table, the individual score values are lost.
