journal data
Description
Types of sampling used for articles in a sample of journals. Note that columns 2 and 3 do not always sum to column 1; for some articles, the investigators could not determine which type of sampling was used. When working with these data, you may wish to create a fourth column, "indeterminate", which equals column1 - (column2 + column3).
Usage
