Matched Pairs Platform Options

The following table describes the options in the Matched Pairs red triangle menu.


Plot Dif by Mean	Shows or hides the plot of the paired differences by paired means. For a detailed description of this plot, see Difference Plot and Report.
Plot Dif by Row	Shows or hides the plot of paired differences by row number.
Reference Frame	Shows or hides the reference frame on the Plot Dif by Mean plot. A rectangle showing where a plot of Y2 by Y1 would be located inside the plot, tilted and possibly squished. A vertical red line is shown representing the mean of means. The reference frame is shown initially when the range of the differences is greater than half the range of the data.
Wilcoxon Signed Rank	Shows or hides the Wilcoxon signed rank test. The Wilcoxon signed rank test is applied to the paired differences. It is a nonparametric test that compares the sizes of the positive differences to the sizes of the negative differences. The test uses the Pratt method to address zero differences. The test also assumes that the distribution of differences is symmetric. For details, see Statistical Details for the Wilcoxon Signed Rank Test in Distributions. See also Lehman (2006), Conover (1999, page 350), and Cureton (1967).
Sign Test	Shows or hides the sign test. This is a nonparametric version of the paired t-test that uses only the sign (positive or negative) of the difference for the test.
Set α Level	Changes the alpha level used in the analyses. Affects the confidence intervals in the report and on the plot.
Script	This menu contains options that are available to all platforms. They enable you to redo the analysis or save the JSL commands for the analysis to a window or a file. For more information, see Using JMP.
