More information
This test compares the differences between the means of two or more samples. For each pair of means in which the difference is significant at the chosen level, the ID of the smaller column(s) is printed next to the figures in the larger column, as for the T-test on column proportions in
T-test on column proportions.
If two confidence levels have been defined, the ID is shown in uppercase if the test was significant at the higher level, or in lowercase if it was significant at the lower level.
To request a Newman-Keuls test
▪Insert a tstat nkl statement after the tab statement of the table to be tested or after the l statement of the axis to be tested.
The test is applied to all rows for which the tstat flag is set. If the row is an n12, then the calculation uses the means formulae; if not, the propns formulae are used.
The information in
P-values for a T-test on column proportions also applies to the Newman-Keuls test.
