French term

étendue

French to English Bus/Financial Mathematics & Statistics statistical analysis section in a clinical trial
I've checked the previous questions/glossaries but I'm not sure which to choose (if any) as I don't really understand statistics. In the efficacy analysis paragraph of a statistical analysis report for a clinical trial, it says "pour les variables continues ou ordinales à l'aide de moyenne (standard deviation), médiane et étendue (Min-Max) et données manquantes". It seems to me as if something is missing from the sentence as well, but I may be wrong of course!

Discussion

Francesca Matteoda (asker) Jan 9, 2008:
I'm afraid it is a paragraph on its own and does not really follow on from the previous one :-(
Tony M Jan 9, 2008:
Right, thanks for that important clarification. On the face of it, it certainly looks incomplete, then — unless it follows on from the previous one? Perhaps it would help to give that too?
Francesca Matteoda (asker) Jan 9, 2008:
This IS the complete sentence, which is why I say I think something is missing. Pour should have a capital P, sorry about that
Tony M Jan 9, 2008:
You say "...something is missing from the sentence", but it doesn't seem as if what you have posted is the complete sentence anyway — 'pour' starting with no capital. Can you confirm this for us, please?

agree chris collister : moyenne is average, so I don't know what it's doing in brackets; standard deviation is écart type. The third measure of central tendency is the mode.

There does seem to be a verb missing somewhere along the line.

spread

I believe this is another term also used in statistics, though it may not necessarily be exactly appropriate in your particular context.

It is made quite clear in the text quoted that 'étendue' refers to the range of values between between Val. min and Val. max, which is far from being the same as the 'standard deviation', which relates to the mean of the set of valiues.

In any case, the correct FR term for SD is 'écart type', and I find it hard to believe that in such a serious document the writers would have made such an elementary error!

Here's just one Ghit that happens to define 'étendue' as 'spread' in a statistical context:

SECTION EURO Maths/Anglais au lycée Blaise PASCAL de Longuenesse

Geometry; Equations and inequations; Statistics; Probabilities; Functions ...

the range, l'étendue.

And here's another that highlights the way 'étendue' is used in relation to 'médiane' while SD is used in relation to mean:

That said, though, I think Kari is right: the 'spread' is more likely to express how widely values are distributed, rather than to describe the full range of values encountered. Here is another Ghit that illustrates this:

Summary Statistics in Excel-

Actually, though, re-reading the question, I think 'étendue' is indeed being used in this way; it seems that it is being used in a way that is analagous with the SD, but in relation to the median, and in that case, 'spread' is definitely the right meaning, and it is in fact NOT necessarily the same as the overall range.
Peer comment(s):
neutral Kari Foster : I'm sure this is a related term, but probably would have been "écart" in French.
13 mins
Thanks, Kari! Possibly not in the context of statistics, though, because of possible confusion with 'écart (type)'
neutral Richard Benham : I am *not* an expert, but I have heard SD referred to as a "measure of spread"; so I would be careful about using "spread" here. Note too that the source specifically says Min-Max (although Max-Min might make more sense if the "-" is a minus sign!)

Thanks, RB! although Wiki deos seem to supprot the use of 'range' (i.e. extent to which data spread either side of median), 'spread' seems to be used quite a lot too, and I think the usage in connection with SD is much less common.
disagree rkillings : This is about a measured statistic, not about an explanatory concept like 'spread' or 'dispersion'.

I don't quite see how you are extrapolating that from the rather slim context?
