WinCross selects Z-Test

Choose WinCross selects Z-Test to let WinCross choose the appropriate statistical test for percents.

WinCross determines from the structure of the table which test to apply. If the banner is LOC+/VAR+, WinCross will always choose the Dependent Paired/Overlap (LOC+/VAR+) test, otherwise, WinCross will choose the Dependent Paired/Overlap (Multi) test. If the data are independent, the Dependent Paired/Overlap (Multi) test is the same as the Independent (using unpooled proportions) test.

Z-Test Options

Confidence Levels

Select one or two confidence levels for the chosen test.
You can choose 1 or 2 confidence levels from the pre-listed percentages or specify custom confidence level percentage(s).
WinCross will not allow you to specify a pre-listed percentage and specify a custom confidence level percentage.

Options

Select Show significance indicators in banner if you want the significance annotation displayed for each banner column.

Note: The Exclude cells that are 0% from analysis option is automatically selected and disabled if you are using the WinCross selects Z-Test or Dependent Paired/Overlap (Multi) statistical testing options. You cannot show significance against blank cells for these two statistical tests.
