raw data summary table for eye color based on raw data • 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. 602 Using Data & Statistics
