jmp.com/learnrev 07/2012Mosaic Plot and Contingency TableUse to examine the relationship between two categorical variables. A contingency table shows the frequencydistribution of the variables in a matrix format, while a mosaic plot graphically displays the information.The Contingency Table AnalysisExample: Car Poll.jmp (Help Sample Data)1. Select Analyze Fit Y by X.2. Click on a categorical variable from Select Columns, and click Y,Response (categorical variables have red or green bars).3. Click on another categorical variable and click X, Factor.4. Click OK. The Contingency Analysis output will display.Mosaic PlotThe mosaic plot is a side-by-side divided bar chart that allows you tovisually compare proportions of levels of one variable across thelevels of a second variable.Interpretation:1. The widths of horizontal bars represent the proportions of the levelsof the X variable (in this example, marital status).2. The heights of vertical bars on the far right represent theproportions of the levels of the Y variable (type).X MarriedY Family3. The cells in the plot represent the proportions for everycombination of category levels. In this example, Married and Familyis the largest overall proportion.Contingency TableThe body of the contingency table displays: Count – the cell frequencies (counts).LegendTotal % - the cell’s percentage of the total count.Col % - the cell’s percentage of the count for the column. Thecolumn variable is the Y variable, type.Row % - the cell’s percentage of the count for the row. The rowvariable is the X variable, marital status.The borders of the contingency table display the column totals (across thebottom), row totals (on the right), and the grand total (lower right corner).Tips: Click on the red triangle next to Contingency Table to select or deselect display options.Right-click on the mosaic plot to change colors (Set Colors) or label cells (Cell Labeling).Note: See the Basic Analysis and Graphing book (under Help Books) for more details.
jmp.com/learnrev 07/2012Histograms, Descriptive Statistics, and Stem and LeafUse to display and describe the distribution of continuous (numeric) variables. Histograms and stem and leafplots allow you to quickly assess the shape, centering and spread of a distribution. For categorical (nominal orordinal) variables, see the page Bar Charts and Frequency Distributions.Histograms and Descriptive Statistics1. From an open JMP data table, select Analyze Distribution.2. Click on one or more continuous variables from Select Columns, and click Y, Columns (continuous variableshave blue triangles).3. Click OK to generate a histogram, outlier box plot and descriptive statistics. The percentiles, including quartiles and the median, are listed under Quantiles. The sample mean, standard deviation and other statistics are listed under Summary Statistics.Example: Car Physical Data.jmp (Help Sample Data)Tips: To change the display from vertical to horizontal (as shown), click on the top red triangle and select Stack.To change the graphical display for a variable, or to select additional options, click on the red triangle forthat variable.To display different summary statistics, use the red triangle next to Summary Statistics.To change all future output to horizontal, go to Preferences Platforms Distribution, click Stack andHorizontal, then click OK.Stem and Leaf PlotTo generate a stem and leaf plot, click on the red trianglefor the variable and select Stem and Leaf.Tips: A key to interpret the values is at the bottom of the plot. The top value in this example is 4300, the bottomvalue is 1700 (values have been rounded to the nearest 100).Click on values in the stem and leaf plot to select observations in both the histogram and the data table. Or,select bars in the histogram to select values in the stem and leaf plot and data table.Note: For more information, see the book Basic Analysis and Graphing (under Help Books).

jmp.com/learnrev 07/2012Interactive Graphing with Graph BuilderUse Graph Builder to interactively create graphs for one or more variables, including line plots, splines, boxplots, bar charts, histograms, mosaic plots, maps and more.Drag and Drop to Visualize DataExample: Big Class.jmp (under Help Sample Data)1. From an open JMP data table select Graph GraphBuilder.2. Drag a variable from the Variables list and drop it in thedesired drop zone. In the examples (right), Weight is in the Yzone and Height is in the X zone.3. To add a grouping variable, drag and drop a variable in theGroup X or Group Y zone. In the example, Sex is in theGroup X zone.4. To change the graphical display, click on a graph elementicon. Or, click and drag an icon onto a graph frame. Here,Line of Fit has been selected.5. Change Summary Statistics and other display options forthe selected graph elements.6. Click the Done button (top left) when finished.Tips: Right-click in the graph to change graph properties. To replace a variable with a new variable, drag the newvariable and drop it in the center of the drop zone. By default, Graph Builder displays data points. If continuous variables are in both the X and Y zones a smoothspline will display (lambda 0.05). More than one variable can be assigned to an X or Y zone, or to a group zone. Drag avariable to either side of the existing variable in the zone – a blue ribbon will indicatewhere the new variable will be placed when dropped. To change the modeling type (to use different graph elements), rightclick on the variable and select the new data type (if available).Other Drop Zones: Drop a variable in Wrap to trellis the graph horizontally and vertically.Drop a variable in Color to create a legend and color by values of the variable.Drop a variable in Overlay to color and overlay graphs for each value of the variable on one graph.If data has been summarized (a frequency variable exists), drag the variable to the Freq zone.If a column defines a physical shape, drag the variable to Shape to create a map (shape files must exist).Drop a variable in Size to scale markers or map shapes according to the value of the size variable.Note: Instructions also apply to the iPad Graph Builder Application (see jmp.com/iPad). For more details oncreating interactive graphics with the Graph Builder, see the book Basic Analysis and Graphing (under Help Books) and other one-page guides (at jmp.com/learn).
