This article describes how to set the default type of Significance Test so that the same method is applied to all tables in the **Project**.

## Method

- From the toolbar, select
**Edit Project Options > Customize > Statistical Assumptions**. - Select the
**Significance Levels**tab (if necessary)

Let's say we would like to change the default settings for **Overall significance** to **0.100 **(a 90% confidence interval) and **Minimal sample size for testing** to **30**

- In the
**Overall significance level**box, type**0.100** - In the
**Minimal sample size for testing**box, type**30** - Click
**OK**

### Restore all the fields to their default values

- From the toolbar, select
**Edit > Project Options > Customize > Statistical Assumptions** - Click the
**Restore**button
