Filtering is a key part of doing research. And that’s why Crunch makes it easy to do filtering. You don’t need your DP to set up filtering for you.
You can do simple filters and more advanced filters. You can do both in Crunch with drag-and drop. Alternatively, you can go back to your DP to set up a filter, but you shouldn’t need to.
Notice that there is a Filters part in the top-left of the Main Area. The following example shows 'Filters None":
The easiest way to apply a filter is to find the variable you want to use as a filter and drag it over into the main area and release into a Filters slot.
- Find Male variable over in Accordion (located in the Demographics folder).
- Click and drag (by left-clicking) the Gender variable to the Main area.
- Drop the gender variable into the grey Filter by box that appears at the top of the Main area.
The filter drop-down menu appears, which prompts you to click a particular category to filter.
- Click Male. The entire dataset is now filtered to respondents who are Male.
Note the sample size at the bottom of the screen is N = 32,736:
Adding more than one filter at a time
You can add additional filters to drill down further into the sample data. The following example describes how to add a '30–44' age filer to the Male filter that was previously created:
- Click Demographics in the Accordion.
- Click and drag (by left-clicking) the Age variable to the Main area.
- Drop the age variable into the grey Filter by box that appears at the top of the Main area.
- Specify the category you wish to use. Both 'Males' and '30-44' are now filtered, so N = 3,453.
- Add additional filters as needed using the above procedure.
- To turn off a filter and return to no filters applied, mouse over and click the small X.
You can build even more complex filters that have Boolean logic. Boolean logic lets you do OR or NOT statements, as well as ANY OF or NONE OF. We’ll come back to this later, but you can read more about using the Filter Builder here including how to save filters for easy recall.
Another related feature to filters is using Tabs - a neat feature we’ll explore in the next bit.
