Document Summary
Chapter 2 frequency distributions frequency distribution - an organized tabulation showing the number of individuals located in each category on the scale of measurement. Range - the obvious first step toward defining and measuring variability is the range, which is the distance covered by the scores in a distribution, from the smallest score to the largest score. The width of each interval should be a simple number (e. g. , 2, 5, or 10). The bottom score in each interval should be a multiple of the width. All intervals should be the same width, and they should cover the range of scores with no gaps. grouped frequency distribution table - a table presenting groups of scores rather than individual values. Class interval - the groups of scores. apparent limits - values that appear to form the upper and lower boundaries for the class interval histogram - you first list the scores (measurement categories), equally spaced along the x-axis.
