## Confidence levels for T-Test and Z-Test

You can select the confidence level that you require for the Z-Test (column proportions) and T-Test (column means). The default setting is 95%, but your options are from 99,99% down to 50%. By default, OfficeReports will display the difference with Capital letters.

Optionally a Confidence level 2 can be added in the test. The test level must be lower than Confidence level 1. By default, OfficeReports will display the difference with Lower case letters. This means that we in one table can include both a significance test on i.e. a 95% and a 90% level of confidence.

You can define that the significance test requires a minimum number of observations. Office Report suggest a base of 30, and the information can be added into tables, by added a referring Character.

The base notification on frequency tables and cross-tabs is based on the column base, except situations where Cell values are summary statistics of a numerical variable, where the notification is based on the cell base.

Observe: The notification is based on the unweighted base.

You can define that OfficeReports detects and show cells where the number of observation is low. By default, OfficeReports suggests a base of 100 or lower. The information can be added into tables, by added a referring Character.

The base notification on frequency tables and cross-tabs is based on the column base, except situations where Cell values are summary statistics of a numerical variable, where the notification is based on the cell base.

Observe:

The notification is based on the unweighted base.

By default, OfficeReports shows Minimum Base and Low Base only combined with significance testing. If Minimum Base and Low Base notifications are relevant also for tables/charts that does not include significance testing, you must add a checkmark for ‘Always show base notifications’.
