Visualizing a Bell Curve With Sliders?

Aug 11, 2016

Hi everyone,

Looking for any available options to use a slider for a learner to indicate the score they have received on a proctored test, where it would then identify their ranking. For instance 0-40 would be low, 45-55 average, 60-100 high.

The kicker is that the slider has to appear as if it is on a bell-curve to represent that most people will fall in the average category. Therefore, the space between 45-55 would have to be much wider than the low or high categories, where the scale is compressed.

But as far as Storyline is programmed, a slider can only have one, evenly divided scale, correct?

Thanks for the sample, Wendy.

You took a similar approach to what we initially tried, but did not meet the client's expectation. There's an additional requirement that both the actual score and corresponding percentile need to be referenced—preferably in the same graphic/slider.

I know there's no way that the slider can have two different scales, or a scale that has unevenly distributed stops, so I think we'll need to look at a different approach than using the slider.

Thanks for helping to confirm our suspicions!

Hi Michael,

I took at a stab at it. I think this is doable if you make all of the potential scores separate states and just write triggers for low, medium, and high manually. That way, you can show visually, they have a different distribution. I only did scores 1 through 5 -- and there would need to be 100 -- but you get the idea...

However, I couldn't figure out how to make the slider function backwards. Hope this helps!
