Excel - Using max, if & and together - excel

I'm trying to use an AND operator inside MAX and IF functions and am having trouble. I want to find the maximum value from column C where both are true:
column A = $D$1
the max only considers the top 80% of the values in column B
So in the example below, the answer would be 7, since of the rows with column A = "foo" and the top 80% of column B which are 3,4,5,6 the max value is 7.
I have two components working:
=MAX(IF($A$1:$A$12=$D$1,$C$1:$C$12))
returns 12
=MAX(IF(B1:B12>PERCENTILE(B1:B12,0.2),C1:C12))
returns 8
If I put them together like this it returns 0 (even with ctrl+shift+enter):
=MAX(IF(AND($A$1:$A$12=$D$1,B1:B12>PERCENTILE(B1:B12,0.2)),C1:C12))
The solution with both AND clauses should be 7
Can anyone help with this?

please modify array formula to:
=MAX(IF(A1:A12=$D$1,IF(B1:B12>PERCENTILE(B1:B12,0.2),C1:C12)))
end with ctrl+shift+enter

Multiplying the booleans together did the trick:
=MAX(IF(($A$1:$A$12=$D$1)*(B1:B12>PERCENTILE(B1:B12,0.2)),C1:C12))
I don't know why multiplying works but AND doesn't. God I hate Excel.

How to select a column IF [duplicate]

Is there a formula that returns a value from the first line matching two or more criteria? For example, "return column C from the first line where column A = x AND column B = y". I'd like to do it without concatenating column A and column B.
Thanks.
True = 1, False = 0
D1 returns 0 because 0 * 1 * 8 = 0
D2 returns 9 because 1 * 1 * 9= 9
This should let you change the criteria:
I use INDEX/MATCH for this. Ex:
I have a table of data and want to return the value in column C where the value in column A is "c" and the value in column B is "h".
I would use the following array formula:
=INDEX($C$1:$C$5,MATCH(1,(($A$1:$A$5="c")*($B$1:$B$5="h")),0))
Commit the formula by pressing Ctrl+Shift+Enter
After entering the formula, you can use Excel's formula auditing tools to step through the evaluation to see how it calculates.
SUMPRODUCT definitely has value when the sum over multiple criteria matches is needed. But the way I read your question, you want something like VLOOKUP that returns the first match. Try this:
For your convenience the formula in G2 is as follows -- requires array entry (Ctrl+Shift+Enter)
[edit: I updated the formula here but not in the screen shot]
=INDEX($C$1:$C$6,MATCH(E2&"|"&F2,$A$1:$A$6&"|"&$B$1:$B$6,0))
Two things to note:
SUMPRODUCT won't work if the result type is not numeric
SUMPRODUCT will return the SUM of results matching the criteria, not the first match (as VLOOKUP does)
Apparently you can use the SUMPRODUCT function.
Actually, I think what he is asking is typical multiple results display option in excel. It can be done using Small, and row function in arrays.
This display all the results that matches the different criteria
Here is an answer that shows how to do this using SUMPRODUCT and table header lookups. The main advantage to this: it works with any value, numeric or otherwise.
So let's say we have headers H1, H2 and H3 on some table called MyTable. And let's say we are entering this into row 1, possibly on another sheet. And we want to match H1, H2 to x, y on that sheet, respectively, while returning the matching value in H3. Then the formula would be as follows:
=INDEX(MyTable[H3], ROUND(SUMPRODUCT(MATCH(TRUE, (MyTable[H1] & MyTable[H2]) = ($x1 & $y1),0)),0),1)
What does it do? The sum-product ensures everything is treated as arrays. So you can contatenate entire table columns together to make an array of concatenated valued, dynamically calculated. And then you can compare these to the existing values in x and y- somehow magically you can compare the concatenated array from the table to the individual concatenation of x & y. Which gives you an array of true false values. Matching that to true yields the first match of the lookup. And then all we need to do is go back and index that in the original table.
Notes
The rounding is just in there to make sure the Index function gets back an integer. I got #N/A values until I rounded.
It might be more instructive to run this through the evaluator to see what's going on...
This can easily be modified to work with a non table - just replace the table references with raw ranges. The tables are clearer though, so use them if possible. I found the original source for this here: http://dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/. But there was a bug with rouding values to INTs so I fixed that.

Sum row based on criteria across multiple columns

I have googled for hours, not being able to find a solution to what I need/want. I have an Excel sheet where I want to sum the values in one column based on the criteria that either one of two columns should have a specific value in it. For instance
A B C
1 4 20 7
2 5 100 3
3 100 21 4
4 15 21 4
5 21 24 8
I want to sum the values in C given that at least one of A and B contains a value of less than or equal to 20. Let us assume that A1:A5 is named A, B1:B5 is named B, and C1:C5 is named C (for simplicity). I have tried:
={SUMPRODUCT(C,((A<=20)+(C<=20)))}
which gives me the rows where both columns match summed twice, and
={SUMPRODUCT(C,((A<=20)*(C<=20)))}
which gives me only the rows where both columns match
So far, I have settled for the solution of adding a column D with the lowest value of A and B, but it bugs me so much that I can't do it with formulas.
Any help would be highly appreciated, so thanks in advance. All I have found when googling is the "multiple criteria for same column" problem.
Thanks. That works. Found another one that works, after I figured out that excel does not treat 1 + 1 = 1 as I learnt in discrete mathematics, but as you say, counts the both the trues. Tried instead with:
{=SUM(IF((A<=20)+(B<=20);C;0))}
But I like yours better.
Your problem that it is "summing twice" in this formula
={SUMPRODUCT(C,((A<=20)+(C<=20)))}
is due to addition turning first TRUE plus the second TRUE into 2. It is not actually summing twice, because for any row, if only one condition is met, it would count that row only once.
The solution is to transform either the 1 or the 2 into a 1, using an IF:
={SUMPRODUCT(C,IF((A<=20)+(C<=20))>0, 1, 0)}
That way, each value in column C would only be counted at max once.
Following this site you could build up your SUMPRODUCT() formula like this:
=SUMPRODUCT(C,SIGN((A<=20)+(C<=20)))
So, instead of a nested IF() you control your or condition with the SIGN()function.

If you plan to use a large set of data then it is best to use the array formula:
{=SUM(IF((A1:A5<=20)+(B1:B5<=20),C1:C5,0))}
Obviously adjust the range to suit the data set, however if the whole of each column is to form part of the formula then you can simply adjust to:
{=SUM(IF((A:A<=20)+(B:B<=20),C:C,0))}
This will perform the calculation on all rows of data within the A, B and C columns. With either example remember to press Ctrl + Shift + Enter in order to trigger the array formula (as opposed to typing the { and }).

Median/average does not return the right values

Image for reference
I'm trying to achieve the following:
if(cell A1 is found in list 1), for each row in which it's found and if(C4:C10 > B4:B10), then median(the subtraction between C and B values, for every row that has text1).
I've tried two 2 different formulas:
1 - {=MEDIAN(IF(AND((C4:C10>B4:B10);(B4:B10=A1));(C4:C10-B4:B10)))}
2 - {=MEDIAN((C4:C10>B4:B10)*(B4:B10=A1)*(C4:C10-B4:B10))}
For median it always returns 0 and for the average really small values that aren't accurate. I'm sure the median and the averages aren't correct.
What would the problem be?
Also, how would I use something like:
{=MEDIAN((C4:C10>B4:B10)*(B4:B10=A1)*(C4:C10-B4:B10))}
If one the columns had text in some rows? (which isn't the case for the former problem, but it has arisen before).
text1
list 1 list 2 list 3
text2 1 5
text4 2 4
text1 4 6
text4 1 6
text1 4 5
text4 2 4
text1 3 3
You can't use AND function in these type of formulas because AND returns a single result (TRUE or FALSE) not an array as required.
Your second formula is closer but by multiplying all the conditions you will get zeroes for every row where the conditions are not met, hence skewing the results.
You can use either one of these similar versions:
=MEDIAN(IF((C4:C10>B4:B10)*(A4:A10=A1);C4:C10-B4:B10))
=MEDIAN(IF(C4:C10>B4:B10;IF(A4:A10=A1;C4:C10-B4:B10)))
both need to be confirmed with CTRL+SHIFT+ENTER
To handle text in columns B or C (and to make the formula ignore those rows but work otherwise) you can add an extra IF function like this
=MEDIAN(IF(C4:C10>B4:B10;IF(A4:A10=A1;IF(ISNUMBER(C4:C10-B4:B10);C4:C10-B4:B10))))
All formulas will work equally well with AVERAGE function in place of MEDIAN
Another way to get the MEDIAN while ignoring text is to use AGGREGATE function like this:
=AGGREGATE(17;6;C4:C10-B4:B10/(C4:C10>B4:B10)/(A4:A10=A1);2)
That doesn't need "array entry" but will only work in Excel 2010 or later versions. There's no simple equivalent for AVERAGE
17 denotes QUARTILE function - second quartile is the equivalent of median
See attached screenshot demonstrating the last two formulas with your sample data....and some added text
Supposing that the values in column C that is list 3 are bigger than those in column B that is list 2, then you can use the following formula:
=MEDIAN(IF((A4:A10=A1)*(C4:C10>B4:B10);C4:C10-B4:B10))
this is an array formula, so press ctrl+shift+enter to calculate the formula.
tell me if it doesn't work.

Excel Summing Up

I have this, for example:
ColA ColB
X 1
Y 2
Z 3
X 4
I want to be able to summarize all values in Column B which
Column A=X or
Column A=Y.
The result should be 7 (1+2+4).
I did this:
SUM(IF(COUNTIF(A:A,"X"),VLOOOKUP("X",A:B,2,),"0"), IF(COUNTIF(A:A,"Y"),VLOOOKUP("Y",A:B,2,),"0"))
For some reason, it returns 3. It doesn't adds the second value of X for some reason.
Any ideas why?
Thanks!
=SUMPRODUCT(((A2:A5="X")+(A2:A5="Y"))*(B2:B5))
If you select a portion of the formula and press Ctrl+=, you can see how it is evaluated.
=SUMPRODUCT((({TRUE;FALSE;FALSE;TRUE})+({FALSE;TRUE;FALSE;FALSE}))*(B2:B5))
Now when those two arrays are added together, the TRUE is coerced to a 1 and the FALSE to a zero.
=SUMPRODUCT(({1;1;0;1})*(B2:B5))
The resulting array of 1's and 0's is multiplied by the array from B2:B5.
=SUMPRODUCT({1;2;0;4})
And summed up to 7.
Your formula returns an error (tooo many o’s!) but with VLOOKUPs 3. Since the problem is not with Y, simplify the issue by taking out that part of the formula:
=IF(COUNTIF(A:A,"X"),VLOOKUP("X",A:B,2,),"0")
This results in 1. But so does:
=VLOOKUP("X",A:B,2,)
Hence COUNTIF(A:A,"X") (which returns 2 because there are two instances of X) does not actually help. Replaced with 7, or 103 or 5=5 - no difference.
You are obviously aware that plain vanilla VLOOKUP stops ‘searching’ once it finds the first instance that meets its ‘rules’ but unfortunately inserting a 2 with COUNTIF is not enough to ‘tell’ VLOOKUP “after finding the first match, now go off and find the second as well”.
So an answer to your question as expressed is “Yes. VLOOKUP cannot be made aware of multiple instances with the =COUNTIF function.”

Permutations in Excel

I am have a string with 6 spaces, e.g. 000000. Each space can hold one of three digits - 0, 1, or 2. I know that I can get a total of 120 permutations using the Permut function in Excel, i.e. =PERMUT(6,3) = 120. But I would actually like to have each individual permutation in a cell, e.g. 000001, 000010, etc.. Ideally, the end result would be 120 rows of unique 6-digit IDs.
Please help if you know a faster way of accomplishing this without entering the figures manually.
Thanks!
There is a VBA functionin the last post on this page. Copy it into a VBA module, then in Excel, create a column of integers from 0 to n where n = the number of IDs you want. In the next column, call the VBA function with the value from the first column as the first argument, and 3 as the second argument. Something like
Column A Column b
0 =baseconv(A1, 3)
1 =baseconv(A2, 3)
2 =baseconv(A3, 3)
... etc.
Your IDs are really just incremental values using a base 3 counting system. You can format the output to get leading zeros with a custom format of '000000'.
Incidentally, with 6 positions and 3 available values, you can get 3 ^ 6, or 729 unique IDs
First, I don't think you're using PERMUT correctly here. What PERMUT(6,3) gives you is the total number of ways to arrange three things picked out of a set of six things. So the result is 120 because you could have 6*5*4 possible permutations. In your case you have 3^6 = 729 possible strings, because each position has one of three possible characters.
Others have posted perfectly fine VBA-based solutions, but this isn't that hard to do in the worksheet. Here is an array formula that will return an array of the last six digits of the ternary (base-3) representation of a number:
=FLOOR(MOD(<the number>,3^({5,4,3,2,1,0}+1))/(3^{5,4,3,2,1,0}),1)
(As WarrenG points out, just getting a bunch of base-3 numbers is one way to solve your problem.)
You would drag out the numbers 0 through 728 in a column somewhere, say $A$1:$A$729. Then in $B$1:$G$1, put the formula:
=FLOOR(MOD(A1,3^({5,4,3,2,1,0}+1))/(3^{5,4,3,2,1,0}),1)
remembering to enter it as an array formula with Ctrl-Shift-Enter. Then drag that down through $B$729:$G$729.
Finally in cell $H$1, put the formula:
=CONCATENATE(B1,C1,D1,E1,F1,G1)
and drag that down through $H$729. You're done!
