Votes to reclassify question as PRO/non-PRO:

PRO (2): luskie, Egil Presttun

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

English term (edited): nonrandom disappearance of certain
Selected

biased

this means that the disappeared subjects did not disappea regardless of their characteristcs - they were for example more males than females, or the oldest or the youngest ones, etc. - for this reason, after these defeats, the control group characteristics were biased (a bias being a systematic error), i.e. they were no more randomly ditributed - hence the control group was no more comparable with the experimental or treatment group

some members quit, not in a natural, random way

Some members quit the group, maybe intentionally eliminated or as a result of some other human interferences, therefore, the control group will lose its representativeness and cannot be used as an ideal control group any more.
