The Bookmarks folder will contain 'server' bookmarks and are only available to users with the appropriate permission. See Bookmarks for further information.

Description, Tabulation and Analysis

The tabs at the top of the right frame provide three ways of viewing or analysing the data. For tabular (cube) datasets, Analysis is not available.

Description

The Description tab displays descriptive information about the dataset. When a dataset title is clicked, the Description tab becomes active and the 'Abstract' for that dataset is displayed.

Variable information can also be displyed under this tab by expanding the Variable Description section, and any further sections, until a list of variables is displayed. A variable is indicated by . Select a variable by clicking on its title. The variable title will get underlined and summary statistics will be displayed in the right frame. Any variable level metadata associated with that variable, e.g. question text, will also be displayed.

Tabulation

The Tabulation tab initially displays an empty table. To add a variable to the table, click on a variable in the browse list and select the required option, e.g. add to row. Add more variables as necessary to produce the required tabulation. Once a table has been created, graphs or a map (if available) can be produced. See also Creating Tables, Manipulate Tables, and Graphics.

Analysis

When the Analysis tab is selected, two further options become available - Correlation and Regression.

Correlation is open by default, and Regression can be selected by clicking the appropriate tab. Click on a variable in the browse list to add it to the analysis. For both correlation and regression analyses, scatterplot diagrams are available.
