- For the question regarding the variable _sodium_, the printscreen of the app in the data description says that there are four possible answers. The table within the datadescription however says there are three possible answers. In the downloaded data, we quite often see a ?4? , so it seems the description of the fourth option was forgotten in the metadata table. We assume 4 stands for ?None of the above? as in the app-printscreen. Is that a correct assumption?
- In addition, the variable contains combinations of the numbers one to four, i.e. 421, 14, 32. How should we correctly interpret the variable sodium and the data provided?
