The Table object supports the ability to display the base size. You can define if the weighted or unweighted base size should be displayed, and you can also define if it should be displayed in columns or rows. The image below shows a table with a base size column activated. The base size information is always displayed in italic text.
You can find the base size settings in the Settings tab in the Table panel (as shown in the image below). The image below shows the controls for displaying the base size in tables.
*The Label, Position and Orientation controls appear when “Weighted Base” or “Non-weighted base” is selected in the Base size information dropdown list. The controls are not shown if “Base hidden” is selected.
In the setup, you define the following:
- Should a weighted or unweighted base size be shown (this setting is only applicable if a weighted result is shown in the table)
- The label of the base size
- The position (should the base size be shown in rows or columns)
- The orientation
- The top or bottom row or the most left or the most right column
The ability to select between rows and column will give you more flexibility in situations where both rows and columns are nested. See below for a few different examples of tables showing the base size. The table below shows the base size in columns. In the top table, it is shown in the most left column, and in the bottom table, it is shown in the most right column.
The two tables below show the same result, but in the top table the base size is shown in rows, and in the bottom table the base size is shown in columns.
The number of decimals cannot be adjusted; it is shown with the same precision as the result itself. Though a smart logic is used to trim 0s at the end of the base size value, e.g. if the result is shown with a three-digit precision and the base size is 623.000, it will be displayed as 623. This means that the base size always is shown whole numbers when an unweighted base size is used, even if the result is shown with one or more decimals.
The base size settings are defined per series in the table. In situations where a table shows multiple questions and you know all these questions have the same base size, you can set up the table in two series to get a layout like in the image below. The base size appears once, not once per question (the first series shows the first question as well as the base size of that question. The second series shows the next 3 questions without the base size). The table below shows an example where the base size is only shown for the first series and not for the second. This table uses a % sign as a suffix. As shown, the suffix is not applied to the base size. The suffix/prefix settings are only applied to the result cells.
