Understanding Probability Density Function
For Number Box questions, a Probability Density Function graph will be shown as part of the analysis. The graph shows the distribution of numeric answers submitted for the question. Here is an example of a Probability Density Function graph.
In the graph above we can see that the average (i.e. mean) of responses is around 100 and the responses follow a typical bellshaped (i.e. normal) distribution.
