Hi Dedoosers, today we are hitting you with one of the more advanced uses of Dedoose that will become intuitive after you use it for the first time. Iterative filtering allows you to create the most nuanced data sets you could imagine in Dedoose by…you guessed it, applying filters on filters.
Don’t worry, while it is super useful, this process is not actually hard. All you need to know is what data you are trying to look at! We’ll go ahead with about as complex an example as we can think of to make this explicitly clear. Let’s find out what codes seem to co-occur in excerpts that have the terms “writing” OR “alphabet” in them and are from Hispanic participants with bilingual mothers. That is definitely a mouthful, so we’re going to outline this and suggest you do this for any complex filter:
Our first criterion is composed of 2 keywords, in general it is best to do these first as we’ll need to apply them separately and it is much easier to filter out by descriptors than key terms when layering filters.
Now, we apply the filter for the next term:
That is about it for our first criterion! Any additional terms you may want to include should follow the second set of steps. Now, let’s wrap it up with our bilingual Hispanic mother filters.
With that, we are finished setting up our filter. See? Not so hard and do trust this will be about as difficult as it will get. Now that the filter is finished, we can simply go to the Code Co-occurrence chart and see those counts we wanted to view. (screenshot of chart).
Finally, remember that when you have activated a complex filter you may wish to use in the future, go to the Data Set Workspace when the filter is active and click 'Save Current Set.' Follow the prompts and it will be saved in your library of saved filters that you can reactivate at any time.
