Hi! I'm sorry if this is the wrong forum to post in, but I'm a bigtime
newbie in distress. I've been driving myself crazy here for quite a
few hours trying to figure out how to calculate mean and mode based on
restricted criteria. The problem is that the version of Excel I'm
working in is in Spanish, since I'm working from Barcelona and don't
have the English version on my PC, so it's difficult to grasp some of
the mathematical jargon.

So, can anyone tell me how to calculate averages and modes among a
subset of a group of participants? For instance, if column C lists the
sex of each participant, and columns N - Z, let's say, represent their
various responses to each of the questions on a survey (the columns
represent fields or responses to questions, the rows participants), how
would I calculate the average response for females to the question in
column N, and then copy the same formula through Z for each of the
responses, without altering that the restrictive criteria should be
taken from column C, that is, by sex? I've come up with a sort of
system by using SUMIF divided by COUNTIF, but this becomes a problem
when I attempt to fillin the formula for several columns, as the
offsetting automatically moves the restrictive criteria to the right,
so that it seems like I'd have to go in manually and rewrite column C
cell references in every single formula. The problem is it's a hybrid
formula - the criteria has to stay in one particular column, by the
SUMIF should change depending on the column where I paste the formula.

And how about mode? Can you do the same song and dance for mode, mode
based on one condition of restriction derived from a single column (e.g.
column D is place of birth - I want to calculate the most frequent
response for each question (each column) among only those participants
born in Catalunya (found in column D)

Finally, is there any way to calculate mode by selecting several cells
instead of choosing a range (e.g. mode of N3 Q3 U3 AA3 etc), even if
some of those cells have N/A as their value? This is another one
that's been giving me a headache.

Sorry about the lengthiness, thanks in advance for your help!!

Adeu!
