Organizing Qualitative Data - (2.2 Statistics)

Frequency distribution

Qualitative data of listing of the distinct values and their frequencies

Frequency (count)

The number of times a particular distinct values occurred

Relative-frequency distribution

Qualitative data that is of listing of the distinct values and their relative frequencies

Relative frequency distributions compared to frequency distributions

Relative frequency distributions is better than frequency distributions when comparing two data sets

Relative frequencies fall between

0 and 1, they provide standard for comparison

Pie chart

Disk shaped into wedge-shaped pieces proportional to the relative frequencies of the qualitative data

Bar chart

Displays the distinct values of the qualitative data on a horizontal axis and the relative frequencies (or frequencies or percentages) of those values on a vertical axis
