For studies that collect a quantitative measure of CPD, where the respondent is free to provide any integer (e.g., 13 CPD), '''we will bin responses into the following bins: 1-10, 11-20, 21-30, 31+.''' If some study collected binned responses from the outset, and those bins happen to differ from ours (e.g., 1-5, 6-15, etc.), then we will simply use whatever bins the study has collected. Please contact Scott if your study does something completely different.

In analysis, it is likely easiest to consider the ranges to have the following numerical values
In analysis, it is likely easiest to consider the ranges to have the following numerical values corresponding to each bin.
*1 = 1-10
*1 = 1-10
*2 = 11-20
*2 = 11-20
