How can I properly attribute unpublished data gathered by someone else when using it in my masters thesis?
In my opinion, stating in the introduction &quot;the data were taken in the such and such experiment prepared and run by A.Becede&quot; would be enough. It's not unusual to analyse data from someone else's experiments, especially at MSc level.
Just as a tip, in my field when we cite something unpublished, we cite it as:
&quot;A.Becede - private communication&quot;
or
&quot;courtesy of A.Becede&quot;.
