I really like the idea of asking the evaluator to state how their total sample was chosen, including the random portion.

Subject: Do we need a definition of random?

Dear all,

Things we may want to discuss as input for the next editor draft from reactions in the survey 7 [1]:

2.  ..otherwise we must define "random"
Frederick was so kind to include a few definitions into the survey but I am not sure if we really have to include a definition or explanation of 'random'. There are many ways to select a random sample and I am not sure if we want to put one or more of them into the methodology as it would seem we have a preference.

Part of a possible resolution: No definition or explanation, but we add to the reporting section: "describe how you selected the random sample."

Let me know what you think.
Kindest regards,
