The alpha (α) level of the test.
Select to output the exact P value. The P value in the Mann-Whitney test can be an exact probability or a normal approximation. For a large dataset, computation of the exact computation may require extensive calculation, particularly in cases when there are ties in the observations. For a large sample, we recommend that you clear this check box and output the approximation. Otherwise, the exact probability should be used.
Specify the output result sheet, which includes a Notes table, Descriptive table, Ranks table and Test Statistics table.
