Is it appropriate to describe our methodological mistakes in manuscript? I work outside academia, but am working on a project with a master's student. During data collection, we had some skip-logic errors pop up while administering the survey online and it resulted in some superfluous data. She and her adviser decided to throw out all affected data and only analyze open-field text, and outlined these mistakes in great detail on her master's paper. While writing our joint manuscript for publication, is it appropriate to outline these programming errors?
It would be inappropriate not mention the mishaps in my opinion. But there is no need to document this in great detail, as you mentioned. I would comment during the revision process that you feel the description of the "skip-logic section" is too wordy, and it should be trimmed to be more concise. 

Keep the focus on the positive findings as opposed to mishaps.
