Excel formula: make the average depending on a cell - excel

I want to make a formula that turns in a VBA code that makes the average for column A even though there are some 0 there. I want to divide it by a the number in a cell that counts the objects in column A.
I used to use this formula, but it divides my sum incorrectly because I have 0's (I want to keep the 0's there):
=AVERAGE(Sheet1!$B$2:$B$10000)

The easiest way to do this, is to get the total of column B by using sum(B:B) (or a more specific range, if you want), and the amount of non-blank cells in column A by using counta(A:A) (in my comment I used count which only counts the amount of numbers in the range, counta should count all non-blank cells). You can then divide the former by the latter to get the number you are looking for, resulting in a formula looking something like
=SUM(B:B)/COUNTA(A:A)
If you already have the count of column A in a cell (e.g. E3), it's even simpler, just use something like
=SUM(B:B)/E3

You can use AverageIf for such a purpose, as you can see in my example:
Row/Column A B C D
1
2 2 =AVERAGE(B2:B5) => value 3
3 4 =AVERAGEIF(B2:B5;"<>0") => value 4
4 0
5 6

All combinations of 4 out of 7 columns with totals using excel

I have 7 columns to choose from and I need to pick 4 of those columns and generate a total for each row. I also need every combination of 4, which means I'll have 35 new columns with the totals for each of those combinations showing in each row. I need the code for this and if it can be done only using Excel. Here is an image of the columns and the grayed ones are the 7 columns I'm talking about. My knowledge of Excel is very limited. There are over 1,500 rows if that matters.
multi step approach that is going to use some helper rows. there may be a more elegant formula that will do this, and much slicker options in VBA, but this is a formula only approach.
Step 1 - Generate List of Column Combination
To generate the list 4 helper rows will need to be insert at the top of your data. either above or below you header row. These 4 rows will represent the column number you are going to pick. To keep the math simpler for me I just assumed the 1 for the first column and 7 for the last column. those numbers will get converted to later to account for column in between in your spreadsheet. For the sake of this example The first combination sum will occur in column AO and the first helper row will be row 1. The first combination will be hard coded and it will seed the pattern for the remainder of column combinations. Enter the following values in the corresponding cells:
AO1 = 1
AO2 = 2
AO3 = 3
AO4 = 4
In the adjacent column a formula will be placed and copied to the right. It will automatically augment the bottom value by 1 until it hits its maximum value at which point the value in the row above will increase by 1 and the the value of the current will be 1 more than the cell above. This will produce a pattern that covers all 35 combinations by the time column BW is reached. Place the formulas below in the appropriate cell and copy to the right:
AP1
=IF(AO2=5,AO1+1,AO1)
AP2
=IF(AO2=5,AP1+1,IF(AO3=6,AO2+1,AO2))
AP3
=IF(AO3=6,AP2+1,IF(AO4=7,AO3+1,AO3))
AP4
=IF(AO4=7,AP3+1,AO4+1)
Step2 - Sum The Appropriate Columns
I was hoping to use a some sort of array type operation to read through the column reference numbers above, but I could not get my head around it. Since it was just 4 entries to worry about I simply added each reference manually in a SUM function. Now the important thing to note is that we will be using the INDEX function over the 13 columns that cover the range of your columns so to convert the index number we figured out above, to something that will work to grab every second row, the number that was calculated will be multiplied by 2 and then 1 will be subtracted. That means 1,2,3,4 for the first column combination becomes 1,3,5,7. You can see this in the following formula. Place the following formula in the appropriate cell and copy down and to the right as needed.
AO5
=INDEX($AB5:$AN5,AO$1*2-1)+INDEX($AB5:$AN5,AO$2*2-1)+INDEX($AB5:$AN5,AO$3*2-1)+INDEX($AB5:$AN5,AO$4*2-1)
pay careful attention to the $ which will lock row or column reference and prevent them from changing as the formula is copied.
Now you may need to adjust the cell references to match your sheet.

How to do a little math in the criteria_range of Countifs Functions (using OR in Countif)

The Excel File is like this
A B
1 0
0 1
1 1
0 1
0 0
1 0
I want to use Countifs function to count how many rows have at least one "1" in any columns, like
=Countifs(A:A+B:B,">=1")
or
=Countifs(or(A:A=1,B:B=1))
I know I can add a Column C, let Column C = Column A + B, and then just count Column C; or I can count the total rows and count rows with "0" in both columns, and then calculate Total Row - Both "0". But in real Scenario, I have more complicated situation, so I prefer not using these two solutions.
Use a SUMPRODUCT function to provide cyclic calculation.
=SUMPRODUCT(--((A1:A6)+(B1:B6)>=1))
SUMPRODUCT does not like trying to calculate text values and full column references slow it down so keep your ranges to a minimum. Using the INDEX function can help isolate a dynamic range of true numbers.
Another solution using array formula:
=SUM(IF(A1:A6=1,1,IF(B1:B6=1,1,0)))
Being an array formula, you'll have to enter this formula by pressing Ctrl+Shift+Enter together.
Use =COUNT(A:A)-COUNTIFS(A:A,0,B:B,0) to count both 0 columns and subtract it from the total rows:
Or you can use:
=COUNTIFS(A:A,1,B:B,1)+COUNTIFS(A:A,0,B:B,1)+COUNTIFS(A:A,1,B:B,0)
if it is not clear what it the total number of rows.

Excel: Obtain a column by sorting anotr one values

I need to automatically obtain a sorted column of values from another given column values, like in the sample:
I have I need A unchanged, and also B obtained from A
A A B
-----------------
1 1 0
0 0 0
3 3 1
8 8 3
0 0 8
I mean if the values from A changes, the B should change accordignly...
Is that possible in MS Excel?
Here a sandbox and sample:
http://1drv.ms/1SkqMhS
If you put The formula =SMALL(A:A,ROW()) in B1 and copy down then the cells in B will be linked to the cells in A in such a way that the numbers in B will be the numbers in A in sorted order. This won't be efficient for larger ranges but will work fine for small to medium size ranges.
If you want the numbers to start in a lower row, say B2 because you have a header in B1, adjust ROW() to something like ROW()-1.
A word of warning: Use of ROW() can make a spreadsheet somewhat fragile in that formulas that involve it can change their meaning if rows are inserted or deleted or the block containing the formula is moved to somewhere else. Rather than using ROW(), there is something to be said for adding a helper column which numbers the data in A (which would then be in e.g. B) and referring to these numbers rather than small. For example, in:
If I put the formula
=SMALL($B$2:$B$5,A2)
In C1 and copy down, it works as intended. In response to a question you raised in the comments, I added still another column which gives an index where the corresponding value occurs. To do this I wrote in D2 (then copied) the formula
=MATCH(C2,$B$2:$B$5,0)
Of course. Highlight your range and in the Data tab, click "Sort", then you can choose how you want to sort your data:
If column B has information that is to be used with Column A (like next to A1 is "Car"), and you want to sort the whole table, based on Column A, then just select Columns A and B, then sort by column A.
Found the answer, thanks to John Coleman !
Just some minor details like cell value fixing (with $, like A$2)and the -1+ROW adjustment for the 1 header row!

Using COUNTIFS for a series of values at once

Working a step higher then COUNTIFS, I appose a challenge to write a formula without VBA code. The basic data is combined from 1000s of rows with:
Column A: rows with values from 1 to 3
Column B: rows with values from 1 to 250.
For this purpose lets say, we are looking at all cells of value "1" in column A, that suit value "5" in column B. To find all matches, we'd use COUNTIFS command.
1 1
2 5
1 5
1 7
1 10
3 45
2 12
1 2
2 1
=COUNTIFS(A1:A9;1;B1:B9;5)
The answer here is 1.
Next thing, the "5" in column B belongs to a group, e.g. group from 1 to 9. What would the best way be, to count all the matches in this example, so that for all "1"'s in column A, we'd have to find all matches with values from 1 to 9 in column B?! In the upper example that would result in "4". The obvious solution is with a series of IF commands, but that's unefficient and it easy to make a mistake, that get's easily overseen.
=COUNTIFS(A1:A9;1;B1:B9;"<="&9)
Works only as the upper limit. If I give the third criteria range and condition as ">="&1 it does not work - returns 0.
Gasper
Where the data is in A1:B9, using a lookup table in D1:E10 with letters A-J in column D and numbers 0 to 9 in column E and the following formula in B11 referencing letters entered in A11 and A12:
=COUNTIFS(A1:A9,1,B1:B9,">="&VLOOKUP(A11,$D$1:$E$10,2,FALSE),B1:B9,"<="&VLOOKUP(A12,$D$1:$E$10,2,FALSE))
works, changing the letters in A11 and A12 gives the correct count according to what they correspond to in the looku in D1:E10.
When you say give third criteria range do you mean:
=COUNTIFS(A1:A9;1;B1:B9;"<="&9,B1:B9;">=1")
If so then try:
=COUNTIFS(A1:A9;1;B1:B9;AND("<="&9,;">=1"))
ie have two conditional ranges with the second range having both conditions combined with AND()
Maybe what you want(ed) is:
=COUNTIFS(A:A;1;B:B;">=1";B:B;"<=9")
Almost there. I noticed that three criteria ranges and conditions work only if I use "=" sign in a condition. As soon as I use
=COUNTIFS(A1:A9;1;B1:B9;"<="&9,B1:B9;">=1")
it returns 0. My goal is to eventualy replace the number in a condition with a VLOOKUP command, so the final equation should be smth like
=COUNTIFS(A1:A9;1;B1:B9;"<="&VLOOKUP(...),B1:B9;">=VLOOKUP(...)")
But the "<" and ">" signs mess with this. Still looking for a solution.
This is my entire line, if it offers any further indication. The AND() commands is at the end - and it still results in 0
=COUNTIFS(INDIRECT(CONCATENATE("baza!$";SUBSTITUTE(ADDRESS(1;MATCH("card_type_id";baza!$A$1:$AAA$1;0);4);"1";"");"$2:$";SUBSTITUTE(ADDRESS(1;MATCH("card_type_id";baza!$A$1:$AAA$1;0);4);"1";"");"$15000"));IF(C6="računska";1;0);INDIRECT(CONCATENATE("baza!$";SUBSTITUTE(ADDRESS(1;MATCH(IF($C$4="CC_SI_klasifikacija";"building_classification_id";0);baza!$A$1:$AAA$1;0);4);"1";"");"$2:$";SUBSTITUTE(ADDRESS(1;MATCH(IF($C$4="CC_SI_klasifikacija";"building_classification_id";0);baza!$A$1:$AAA$1;0);4);"1";"");"$15000"));AND("<="&VLOOKUP($C$5;$K$203:$N$223;4;FALSE);">="&VLOOKUP($C$5;$K$203:$N$223;3;FALSE)))

How to return a value to the left of a table array with VLOOKUP?

I need help searching Column E for value=1 and return the value of column A for the same row. VLOOKUP isn't working because there are many columns being searched and there are several 1's in the lookup, and I couldn't seem to search just 1 column using VLOOKUP. Here's how my spreadsheet looks...
A B C D E
1 Name Weight WeightRank Height HeightRank
2 Mike 170 3 6.3 2
3 Richard 200 1 6.0 3
4 Charles 185 2 7.0 1
So I want to search column E for value=1 and return the corresponding value in column A, which in this example would search "HeightRank" for "value=1" and return "Charles"
I tried using =VLOOKUP(1,E:E,1) but that returns an error.
I tried using =VLOOKUP(1,A1:E3,1) but that returns an error.
INDEX(A:A,MATCH(1,E:E,0))
VLOOKUP doesn't work here -- it always searches in the first column of your table and returns a value of a column a given number of columns to the right.
The INDEX/MATCH combination is more flexible, letting you just choose the two columns you want. It's also easier to read (you don't have to count columns to see what it does) and it doesn't break if you insert or delete columns in between the ones you're using, which VLOOKUP does. If you use the trace-formula features, VLOOKUP also falsely implies that all the columns in between are precedents of your resulting formula. (Can you tell that I don't much like VLOOKUP? I just always use INDEX/MATCH and my life is easier for it.)
The OFFSET solution works but it's volatile, so you'll really bog down your worksheet if many cells depend on the result of your formula.
MATCH(x,E2:E4,0) returns the relative position of x in the range E2:E4. For example, MATCH(1,E2:E4,0) returns 3, because 1 is the value of the third cell in the range E2:E4.
OFFSET(A2,r,c) returns the cell r rows and c columns away from A2.
Thus you can say =OFFSET(A2,MATCH(1,E2:E4,0)-1,0) to return the value from column A corresponding to the cell in column E that contains 1.
