Check out a video tutorial here, or keep reading to find out how to apply this feature to your survey data.
Correlation Finder is the newest addition to aytm's Data Lab. To add to your survey click on the Data Lab icon and drag and new Correlation Finder into your report.

Once you have added a new Correlation Finder to your report you can select the Banner and Attribute. Banner and Attribute can be any demographic trait, question or Virtual Question from your survey. Click the drop down to select.
Tip: If you need to switch the banner and attribute you can click the arrow to reverse them.
Banner - what you are studying, also known as the independent variable. It is the underlying factor that can lead to statistical significance.
Attribute - is what you are looking at in order to explore statistical significance. Attributes are dependent variables.
Example: Gender is an independent variable - it doesn't change in response to a stimulus. The answer to a question - a dependent variable - might be influenced based on a respondent's gender. Banner = gender, Attribute = response.
When you are ready click "Generate Data" to populate the chart!
Once the chart populates you can customize the visualization a few ways:
- Toggle between Interlaced & Grouped charts.
- View the data by N - number of respondents or % of total respondents.
- Change the chart type.

Correlation Finder includes live Significance testing, hover or click on any column to view.

Now let's take a look at the data tables! This is where you can view the analysis data for the significance test (t/z-test) or Crosstab (Chi-squared). Select the test you want from the drop down located at the top right of the chart. The default will always be Sig Test (t/z-test).

Now scroll below the chart to the output for your test.
Sig Test Example

Crosstab Example

Click on the Legend at the top left of each table to see an explanation of the analysis.

To change the confidence level for your Correlation Finder click on the Microscope Icon in the left side bar. Adjusting the slider for primary or secondary confidence level here will automatically adjust your Correlation Finder and it will also display in the legend.
Once a Correlation Finder is added to your stats report you can export the chart and data table to PowerPoint or download a static image of the chart.
Correlation Finder performs an analysis on the banner and attribute of your choice right in your results, including a chart. To compare banners across multiple questions, or to obtain the specific p-values and full details of your survey's statistical tests, export a traditional Significance Test from the Analysis (microscope) tab.
