This is really handy if you want to compare entire reports, for example pre and post training surveys, or a survey you did last year compared to this year.
First things first you can only do this if you make sure that your surveys are identical - ie. the same questions using the same questions types with the same options all in the same order. You can still change the title and the wording if you need to.
The easiest way to do this is create one survey, then when you are happy with it clone it and make edits to the wording of the second one if you need to.
To clone a survey - find your survey in your survey folder. Next to the little orange wheel there is a down arrow - click on it, then click on the option "Copy Survey"
Next, go to the copied survey and rename it, in the same way as detailed above - click on the arrow next to the orange wheel and its the first option on the list. See below:
Now you can open up your second survey and make amendments to the language only - do not change the question types, or order of any of the options or questions.
Once your data collection is complete for both surveys, go into the Reports tab - doesn't matter which one. In this example I have a pre and post training questionnaire, and I am using the report tab in the post training questionnaire.
Click on the Combine Reports icon
In the next box you can search for your other survey using a word from the title, or your username. Tick the tick box of the other survey and hit Combine
You will then be asked how you want to present the graphs of the combined report, I tend to use the first one, but you can select whichever you prefer.
And here is what a combined question report looks like:
You can also still do a filter report on a combined report, so in this example I want to see the responses of just the Band 5s (note you can only filter by a closed question type).
Stay within the Combined Report, then click the first icon 'Filter' Select from which of the original surveys you wish to apply the filter in (as they should both be the same this shouldn't matter). Then click the question and option you want to filter by. Then click on Apply.
