We recently graphed some of our WebCDI data and noticed a few funny plots, where a few longitudinal participants would show large spikes in vocabulary for one month in the middle of their participation, and then the plot would go back to normal (see image below for an example).
Looking closer at the data, it seems like perhaps there were limited times when WebCDI was not calculating the totals correctly, because this issue seems most prevalent for children with CDI data from similar time points. Below is a table of a few administrations where we noticed this issue, including the administration ID, the totals as calculated by WebCDI, the totals as calculated by us (summing words produced), the form language (Words and Sentences American English and Quebec French), and the date modified for the administration.
Just wanted to make sure that you are aware of this issue!
