Document Summary

Raw quantitative data comes as a list of numeric values each value is a count or measurement, either discrete or continuous. Comparisons (one value being more than or less than another) can be performed on the data values. Mathematical operations (addition, subtraction, ) can be performed on the data values. Discrete quantitative data can be presented in tables and bar graphs in several of the same ways as qualitative data. Values listed in a table use the discrete values instead of the category names. Use the discrete values instead of the category names and arrange the values in ascending order. Unlike a bar graph for qualitative data, no space is left between the bars and the width of the bars have meaning. Good practices for constructing tables for continuous classes: Have the same width (except for possible open-ended classes at the extreme low or extreme high ends) The lower class limits should be reasonable numbers.
