How to build graphs, charts and plots
![Page 2: How to build graphs, charts and plots. For Categorical data If the data is nominal, then: Few values: Pie Chart Many Values: Pareto Chart (order of bars.](https://reader038.fdocuments.us/reader038/viewer/2022110208/56649dd95503460f94ace41b/html5/thumbnails/2.jpg)
For Categorical data
• If the data is nominal, then:• Few values: Pie
Chart• Many Values:
Pareto Chart (order of bars determined by frequency)
• If the data is ordinal, then:• Bar Graph (order
of bars determined by order of the ranking variable)

For Numerical Data
• Value classes are contiguous intervals that cover all possible data values
• Frequency counts can be made one class at a time (non-cumulative), or one more class every row (cumulative).
• Frequency counts can also be absolute or relative

Histogram and Polygons in PhStat
• To let PhStat graph frequency distributions of the data use the command sequence:→PhStat
→Descriptive Statistics→Histogram & Polygons…

Histogram and Polygons in PhStat
• Then, you input the proper cell ranges in the dialog box for the procedure:• Variable cell range: range of cells for data.• Bins cell range: class limits for classifying
data into tables.• Midpoints cell range to then have PhStat
plot histograms and polygon charts of your choosing.
• Let’s draw the frequency distribution charts for 2.12 using PhStat in Excel during class …
