I want a kind of formula that applies any kind of formula to numbers before summing them.
e.g:
I have values of an angle at column A and I want the sum of the cosine of those angles.
Alternatives like adding another column to calculate the cos then finding its sum will not help since I particularly want to sum the difference between all of values of a column and each single value as a part with other multiplications
e.g
A B
1 7
2 11
3 9
4 8
5 6
I want for cell B1 to have the sum of all numbers after subtracting A1 from each one
same cell B2 to have the sum of all numbers after subtracting A2 from each one.
You can do this without resorting to an array formula:
=SUMPRODUCT(--($A$1:$A$5)*1-A1)

I am trying to use SUMIFS and multiply its output with the a values from the corresponding row. Example:
Example
In This example I will use just 1 criteria for the SUMIFS, but the concept remains the same:
SUMIFS(C2:C5; B2:B5; "=Sum"). This would return 5 + 6 = 11
Now I want to multiple that by the corresponding probability. Meaning 5 * 50% + 6 * 20%: SUMIFS(C2:C5; B2:B5; "=Sum") *
Any idea how to include the probability in the equation?
Thanks!
You can't use SUMIFS for this unless you add a helper column - try using SUMPRODUCT instead
=SUMPRODUCT((B2:B5="Sum")+0;C2:C5;D2:D5)
SUMPRODUCT multiplies all the arrays/ranges and then sums the result, so we can include your value and probability ranges with a conditional array based on "Sum" in the include range
With a helper column you can just use column E to multiply C and D, e.g. this formula in E2 copied down
=C2*D2
and then use SUMIFS like this
=SUMIFS(E2:E5;B2:B5;"Sum")
I have
Year 1 2 3 4 5 6
I'm trying to make it so that each year number 1-6 is equal to another number value i.e. Year 1 is equal to 5. Year 2 is equal to 6.
You will not be able to store one value in a cell and use a different value for calculation. However you may do this calculation with the help of a lookup from another table,
Assuming you have the years in Column A and the corresponding mappings are in Column E and F, you can use the below formula in Column B,
=INDEX(E:F,MATCH(A1,E:E,0),2) * 2
This formula lookups the value in A1 in the table E:F and returns the corresponding Column F element. That is finally multiplied with the 2 to show your result. Instead of just using just A1 for multiplying by 2, you should be using INDEX(E:F,MATCH(A1,E:E,0),2). Hope this helps.
I am looking for formula in Excel to construct cumulative sum for the duplicates.
Item Value Cumulative sum
-----------------------------
A 3 3
A1 4 4
A1 7 11
A1 5 16
B1 20 20
B1 4 24
C 6 6
D 10 10
E 8 8
E 7 15
The table given shows the cumulative for the duplicates in Column 1(Item).
I need excel formula to construct this for my calculations.
Break problems like these down step-by-step.
(Assume your data are in A1:C11 (col C is empty except for the header).)
To calculate a cumulative sum, you just add the current value in col B to the previous value in col C. This is simply =C1+B2 in C2, =C2+B3 in C3, etc.
To evaluate whether you are in the same group of Item, you can simply test whether A2=A1, A3=A2, etc.
To reset your cumulative sum when the group changes, you can use an IF() function. In (2), you have a logical condition. In (1), you have an operation to perform if the condition is true. If the condition is not true, you want to reset the cumulative sum, which is simply the value of col B in the current row.
So to put it together (in C2):
=IF(A2=A1, C1+B2, B2)
Then fill down.
I HAVE A QUESTION ABOUT SUM IN EXCEL:
I have many rows in excel.
I want to calculate sum of each row in one formula
for example
A B C D E
2 3 5 6 8 24
4 5 6 8 9 32
BUT do not USE separate formula FOR EVER CALCULATION (FOR EXAMPLE =sum A1:D1)
CAN I USE WITH ONE FORMULA TO CALCULATE SUM OF EVERY ROWS
You do not have to manually enter the formula to calculate sum of every row.
In the first row you would input =SUM(A1:D1) (did you mean to include E1 as well?)
Then follow the instructions here to apply it the other rows
A B
1 5
2 10
2 15
3 20
I want to calculate percentile for a column of values B if A is equal say 2. That's I want to get range of B2,B3 and calculate percentile of this.
So basically the question is: how do I select range in one column with the checking with another column?
I.e. it works perfectly with SumIf and CountIf, I just need the same with PercentileIf. Thx!
This will give you the 25th percentile of A1:A6 for all cells where the value in B1:B6 equals 2:
=PERCENTILE.INC(IF(B1:B6=2,A1:A6,""),0.25)
It's an array formula and must be entered with Ctrl-Shift-Enter.
