Researchers are accustomed to working with tables where there is more than one question used in the columns. These are often referred to as tabs, banners, or cross breaks, but in Crunch they’re called Multitables.
The following icon shown in the grey bar grey at the top opens Multitables in Crunch:
- Find Unaided Awareness in the Accordion and click on it (in Variables View)
- Click the Multitables icon in the grey bar to jump to the Multitables View
If the dataset you're working with does not have a multitable set up, then you'll skip to the next section which shows you how to easily make one. In this example, the dataset already has a set of multitables created, named Demographics.
The multitable shows Unaided awareness as the rows, and with Gender, Age, and State of Residence at the top. It's the Gender, Age, and State questions that are the banner (columns) and thus define the multitable:
Multitables are often quite wide, so you can scroll to the right using the > arrows on the side of the table.
- Scroll to the right and back to see the full width of the table
Creating your own banner
Suppose you want to create your own banner (multitable). If you're already looking at a multitable, then you just need to click the dropdown next to the name of the banner (top left), and then select New multitable:
If there are no existing multitables stored in the dataset, Crunch will then open the multitable creation area.
To add columns to the banner, you simply select variables from the accordion (as many as you like).
- Select Marital Status, Race, and Education
If you want to hide any particular column, you can do this by selecting it, and then it is be greyed out:
- Click No HS to remove those who haven't attended high school from the banner (this won't appear we look again at the multitable).
You can also add filters to the multitable by putting your mouse over the dropzone and then clicking to reveal your list of filters. Select one to add it as a column in your multitable, or choose New filter to build a new one and immediately add it as a column.
Be sure to give the new multitable a name (top right), and then Save the banner (bottom left).
- Give the banner (multitable) a name: Demographics 2
- Click Save
You can now see your variables broken out by Demographics 2: Marital Status, Race, Education side-by-side along the top.
You can switch between banners, by using the drop-down menu in the top right, next to the multitable's name.
- Change to Demographics (the first one)
If you need to make a change to the banner, you can do that as well, by clicking Edit next to the multitable's name in the drop-down.
- Click Edit next to the multitable Demographics 2
- Go over to the No HS category that was hidden before, and then it click to unhide it
- Click the Save button at the bottom
The No HS category on the multitable is now restored.
The Display Controller (bottom bar that fades in when you hover over it), contains the same functions as when looking at the Tables and Graphs view: changing the statistic shown in the table's cells, hypothesis testing, the direction of arrows. The exception is that you cannot make a multitable into a graph, and you cannot swap the rows/columns (the banner can only be used along the top, not as rows).
