=SUM(SUBTOTAL(9,OFFSET(Range A,ROW(Range A)-MIN(ROW(Range A)),,1))*SUBTOTAL(9,OFFSET(Range B,ROW(Range B)-MIN(ROW(Range B)),,1)))

This seems to be equivalent to

=Subtotal(9, Range C) where Range C = (Range A) X (Range B)

This enables me to eliminate the creation of the large intermediate array C which was only created so that it could be summed with autofilters.

Please confirm or comment if anyone knows of situations where this would not be true.

I used you suggestion but couldn’t get it to work when some data cells in my array were blank… therefore I went back to basics

If anyone is looking to find the geological mean and filter data at the same time this is how I did it:

=SUBTOTAL(6,I4:I37)^(1/(SUBTOTAL(2,I4:I37)))

where I4:I37 is my range
SUBTOTAL (6) gives the product of the cells in the range that are unfiltered
SUBTOTAL (2) counts the number of cells

I know this isn’t about using offset but I thought it applied to some of the suggestions on this (excellent) page

With regards,

Carl

This solution looks fanastic, but I can’t get it to work.

My initial motivations were to apply it to an AVEDEV function across a range, but after my implementation failed, I set about testing the example formula with exactly the same data as shown in your example. I replicated exactly your example and copied the code (right down to the values and named ranges).

The result of applying the sample equation is “#VALUE!” (in both cases).

Using the Evaluate Formula function, I notice that it seems to be failing on the filtering function “Rge1=”Dick”". Where “Rge1? should be shown it displays “#VALUE1? – but everything else seems to resolve properly.

Suspecting that I needed some add-ins, I enabled “Analysis Toolpak” through “Solver Addin” – this has not improved things.

This is an excellent website – if I can get a reply to this, you will make my day!

Thanks for your response.

I must be dim, but I cannot see how that would work?

oesn’t that still require the user to manually re-calculate (regardless of whether they have calculation mode set to automatic or not)?

Thanks for your assistance,

Alan.

Dick: is there a way to edit posts?

A fellow named Domenic responded to a question I had for this same thing. We exchanged several emails – thanks Domenic!

Two things I wanted to know: first how to use other measures of central tendency beyond sum, count, average, stdev, etc. to measure a list of sales ratios. The following array formula was used for median, avedev, geomean, harmean:

{=MEDIAN(IF(SUBTOTAL(3,OFFSET($AF$2:$AF$64,ROW($AF$2:$AF$64)-MIN(ROW($AF$2:$AF$64)),0,1)),$AF$2:$AF$64))}

and works fine.

Also wanted to do a calculation on the same list but for only those visible rows that were compared to a list of parameters. EG list of Quarters (1 – 4) and the central tendency of any visible rows that were in a particular quarter

Give from visible rows
Term Median GeoMean Mean …
1
2
3
4

{=MEDIAN(IF((SUBTOTAL(3,OFFSET($E$2:$E$64,ROW($E$2:$E$64)-MIN(ROW($E$2:$E$64)),0,1)))*($E$2:$E$64=$E67),$AF$2:$AF$64))}

I think the use of Row(…) solves your problem
