602 Using Data & Statistics
• Raw data consists of a single list, such as a list of eye colors. When you
create a plot of raw data, Data & Statistics counts the occurrences for
you. Plotting raw data directly gives you flexibility in analyzing it.
• A summary table consists of two lists, such as eye colors (the
X or Y List) and counts of eye-color occurrences (the Summary List).
For an example that creates a summary table and then plots it, refer
to the “Using Lists & Spreadsheet” chapter.
Working with numeric plot types
Plots can represent the data from a variable in a variety of ways.
Choosing the appropriate plot can help you visualize the data. For
example, you may be able to observe the shape and spread of the data in
one plot type and another type may be useful for determining the best
method for statistically evaluating data. Use Data & Statistics to create
the following types of numeric plots.
•Dot Plot
• Box Plot
• Histogram
• Normal Probability
•Scatter Plot
• X-Y Line
Creating dot plots
Dot plots, also known as dot-frequency plots, represent one variable
data. Dot plots are the default plot type for numeric data. When you plot
a variable as a dot plot, one dot represents each value in the list. Each dot
displays on the axis at a point that correspond to the value.
