Records the frequencies of each level.<br />

Records the sum of the rank score for each level.<br />

Records the expected score under the null hypothesis that there is no<br />

difference among class levels.<br />

Records the mean rank score for each level.<br />

Records the st<strong>and</strong>ardized score. Mean0 is the mean score expected under the<br />

null hypothesis. Std0 is the st<strong>and</strong>ard deviation of the score sum expected<br />

under the null hypothesis. The null hypothesis is that the group means or<br />

medians are in the same location across groups.<br />

Gives the values of the chi-square test statistic.<br />

Gives the degrees of freedom for the test.<br />

Gives the p-value for the test.<br />

Gives the sum of the rank scores. This is reported only when the X factor has<br />

two levels.<br />

Gives the test statistic for the normal approximation test. This is reported<br />

only when the X factor has two levels.<br />

Gives the p-value for the normal approximation test. This is reported only<br />

when the X factor has two levels.<br />

Gives a one-sided p-value for the test. This is reported only when the X<br />

factor has two levels, <strong>and</strong> the exact version of the test is requested.<br />

Exact tests are available only in JMP Pro.<br />

Gives a two-sided p-value for the test. This is reported only when the X<br />

factor has two levels, <strong>and</strong> the exact version of the test is requested.<br />

Exact tests are available only in JMP Pro.<br />

EDF at Maximum<br />

Deviation from Mean at<br />

Maximum<br />

Lists the factor levels occurring in the data.<br />

Records the frequencies of each level.<br />

Lists the value at which the maximum deviation from the empirical<br />

distribution function (EDF) of each level <strong>and</strong> the overall EDF occurs.<br />

Lists the value of the EDF of a sample at the maximum deviation from the<br />

mean of the EDF for the overall sample.
