Talk:Statistics/Methods of Data Collection

design a questionnaire

Contents of the page
This page seems unclear to me. I don't know where this classification comes from and I don't understand how Graphical Method can be classified as a method for data collection. It is a way of displaying data but not collect them. PAC2 (talk)

sections
This chapters has three sections : "Experiments", "Sample Surveys" and "observational studies". In my opinion, there is no opposition between those three items. A researcher can design an experiment and collect the information using a sample survey. I think there is an opposition between "experiments" and "observational studies" and another opposition between "sample surveys" and administrative datasets.
