Find two recent research articles in your field that rely on publicly available data (either shared by the authors themselves or by others). Do they include data availability statements? Are the data cited in the bibliography? If the answer to either of the questions is no, how would a data availability statement/bibliography entry have looked?
The purpose of the first part of this exercise is to get you used to the idea of looking for data availability statements as part of your standard research practices. Where data are available, take a look – you can learn a lot from studying other researchers’ data. Where data are not available, ask yourself why not. For the citation and the data availability statement, check whether your solution has the key elements identified above.
