Hi All!
Curious if this platform can create parallel dotplots of two quantitative variables. For example if I wanted to compare the sampling distributions of two (or more) statistics from an approximate sampling distribution.
Please help!
Hi Timothy,
No, you can’t add two (or more) quantitative variables (attributes) to an axis to create parallel dot plots. Sorry.
As you probably have already discovered, if your two (or more) distributions belong to a single attribute and can be distinguished by a categorical attribute, then it’s easy to get the desired parallel dot plots. I’ve enclosed a screenshot of this.

Is this the kind of thing you are looking for? See shared CODAP doc.
To create this I had a dataset of roller coasters, then used our sampler plugin to create 50 samples with 30 roller coasters randomly chosen from the original dataset for each sample. Then I calculated two statistics for each sample—Mean Drop and Median Drop.
The tricky part was creating a parallel dot plot of these two statistics. To do that I took the two columns, one calculating Mean Drop, and one calculating Median Drop, and using the Transformer plugin to “pivot longer” turned those attributes into a column of stat names and one of the calculated values of those stats for each of the samples.
So, if I’m interpreting your question correctly, you can create parallel dot plots of sampling distributions to compare two or more stats calculated for each of those samples.
