• Dot plots are also known as frequency plots, and represent one-variable numerical data. • Dot plots are the default plot type for numerical data. • One dot represents each value in the list. • Each dot is displayed on the axis at a point that corresponds to the value.

• Box plots are used to plot one-variable numerical data in a modified box. • "Whiskers" extend from each end of the box. • Box plots are used to compare two or more sets of data that use the same scale.

• A histogram plots one-variable numerical data and depicts the distribution of data. • The number of bins displayed depends on the number of data points and how the points are distributed. • A value that occurs on the edge of a bin is counted in the bin to its right.

Shows one set of numerical data against the corresponding quartile (z) of the standard normal distribution.

• Shows the relationship between two sets of numerical data. • You also plot a scatter plot using the Quick Graph tool in the Lists & Spreadsheet application.

• This plot is a type of scatter plot in which data points are plotted and connected in order of appearance in the two variables. • An X-Y line plot depicts the relationship between two sets of data. • The left-most column of data is represented on the horizontal axis.

•

Drag a point to move it. As you move a point, the values associated with the point change in the work area and in the list of variables.

•

To change a variable on an axis, tap the Add Variable region, and then tap another variable name.

From the Tools menu:

-

Tap Plot Type to select another supported plot type.

-

Tap Plot Properties to clear all variables or to modify properties such as add and remove X and Y variables, add a summary list, or force a categorical X.

-

Tap Actions to insert text or sliders. You can also select all points in the plot.

-

Tap Analyze to choose analysis options such as add a moveable line, plot a value or function, or activate the Graph Trace tool.
