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.

Choice of the Non-Inferiority Margin
M or Δ is the non-inferiority margin used in the non-inferiority study. This non-inferiority margin is selected prior to the trial. Non-inferiority margin is the degree of inferiority of the test treatments to the control and the trial will attempt to exclude it statistically.

Méthodologie stricte
La méthodologie d’une étude d’infériorité nécessite quelques conditions supplémentaires par rapport à celle des études de supériorité. McAlister et Sackett (2) mentionnent comme différences nécessaires pour une étude de non infériorité : une analyse par protocole (résultats des patients qui ont réellement pris le médicament) en plus de l’analyse en intention de traiter (résultats de tous les patients inclus dans l’étude), la preuve de l’efficacité du médicament choisi comme contrôle, des patients et des critères d’évaluation similaires à ceux d’études précédentes montrant une efficacité, une application stricte du protocole, une hypothèse nulle appropriée, une marge de non infériorité spécifiée dans le protocole initial. La détermination de la borne ΔC fait l’objet d’âpres discussions et certains experts proposent de la déterminer aussi en fonction de la pathologie et du type de traitement à évaluer (3).

A non-inferiority experiment, by contrast, tries to show that the new intervention is not 'inferior' to the previous one, or, more precisely, that the new intervention is 'not unacceptably worse' than the intervention used as the control. Thus the null hypothesis seems backwards, in a sense, as this hypothesis is not 'null' at all. Instead, it states that the new treatment is worse than the old by more than -Δ, where -Δ is the 'non-inferiority margin'.
