Using OR in an array to calculate percentile

[johnny_trauma]

I can't seem to stay off this board today.

I thought I had figured out this problem, but to my dismay I was grossly mistaken.

I have a formula used to calculate the percentile when two conditions are met, and I am now trying to edit it to contain a third condition. The catch is that either the second or third condition must be true, not both.

My current formula looks like this:

=percentile(if(rangeA=x,if(rangeB=y,rangeD)),0.25)

but I need to add ...if(rangeB=y or rangeC=z,rangeD)...

Any suggestions?

Try:

=percentile(if(rangeA=x,if(or(rangeB=y,rangeC=z),rangeD)),0.25)

I've tried this formula, and the numbers just don't seem to be adding up. It appears that the formula is only taking into account the first condition when coming up with the result.

Everything with rangeA=x is being used in the calculation. Do this make any sense?

Ah-ha. I can't use text in the array, or the OR function will ignore them.

Any thoughts on eliminating this problem, short of transforming the text values (it is a very limited number of values) into some sort of numerical representation?

What are x, y and z? Are they named cells?

If not,

=percentile(if(rangeA="x",if(or(rangeB="y",rangeC="z"),rangeD)),0.25)

Also you don't have any "False" qualifiers...what happens if Range A is not x, y or z?

Try...

=percentile(if(rangeA=x,if((rangeB=y)+(rangeC=z),rangeD)),0.25)

Hope this helps!

That worked like a charm. Thanks for all the help.
