This is purely a math question!
I simply can't get my head around this formula. It is so simple, but I can't get it to work in general.
I have 2 columns of numbers.
Columns A+B is the full number of apples (100%).
Column A: is the number of apples that I have eaten.
Column B: is the number of apples that are left.
I need column C to be the percentage of apples that are left out of the full number.
For example.
A B C
0 3 100%
5 0 0%
2 2 50%
Can anybody wrap their heads around this?
Total = A + B
Left out apples = B
Percentage of left out apples = (B / Total) * 100
Consequently, here's the formula:
Column C = ((Column B) / (Column A + Column B) * 100)
Here's what you should type-in in Excel:
=(B1/(A1+B1))*100
A = No. of apples eaten, B = No. of apples left . A+B = total no of apples. So Total no. of apples left out of the full amount are (A+B)-A/100.

Consider a data table in excel with 6 columns Min, Max, x, 17,18,19 and 3 user input. Output expected is an appropriate cell value to be returned from the table
when
my first userinput value lies within Min and Max(from table)
2nd user input value matching any of the cell in column x
3rd user input matching either 17/18 or 19
For Eg
Sample Data:
Min Max x 17 18 19
-------------------
1 7 0.5 1 2 3/n
8 10 1 2 5 7/n
8 10 2 8 4 9/n
8 10 3 0 7 4/n
11 12 0.5 3 2 1/n
If my user input is (8.4,2,18)
output expected is 4
=INDEX(D2:F6,SUMPRODUCT((A2:A6<=A9)*(B2:B6>=A9)*(C2:C6=A10)*ROW(A2:A6))-ROW(A1),MATCH(A11,D1:F1,0))
Where SUMPRODUCT calculates the row number meeting conditions for min, max and x minus the row number of the header row for correct indexing.
Match calculates the column for indexing.

I am interested in knowing how to calculate a ranking score from ratings of a product. E.g., take the apple appstore. There are two products A and B. Both have same average rating but 100 reviewers have rated A whereas 1000 reviewers have rated B. Intuitively it seems B should be ranked higher than A (it has lower standard error in the mean). Is there an established formula to compare two items and determine which is better based on their ratings?
I write some python code so you can run it easily.
def score(nn):
""" nn = [0, n1, n2, n3, n4, n5] """
if len(nn)==5:
nn = [0, *nn] # add 0
N = sum(nn)
K = 5
kk = [1,2,3,4,5]
z = 1.65 # alpha = 0.1 mean 95% confidence
avg = sum(k*(nn[k]+1)/(N+K) for k in kk)
diff = sum(k**2 * (nn[k]+1)/(N+K) for k in kk) \
- sum(k * (nn[k]+1)/(N+K) for k in kk) ** 2
dev = z * sqrt(diff / (N+K+1))
return avg - dev
You can just call it
score([5, 5, 14, 48, 223]) # 4.517059350728805

I have an Excel file that looks like this:
ZONES Count Area 1 = (SUM OF ZONE COUNT)
------------------------------------------------------------------------------
1 100 1
2 50 2
3 110 5
4 90 7
5 40
6 10
7 0
8 80
What I need to do is make (SUM OF ZONE COUNT) say 190 since 100+40+50+0 = 190. I've tried:
=SUMIFS(B3:B10, A3:A10, C3)
And it will return 100. When I try:
=SUMIFS(B3:B10, A3:A10, "="&C3:C6)
It returns 0.
I need to set the criteria to be a range instead of an individual cell.
Is this possible?
Try this version
=SUMPRODUCT(SUMIFS(B3:B10,A3:A10,C3:C6))
because the criteria range is four cells the SUMIFS function will return an "array" of four values - SUMPRODUCT is used to sum those four values
You can also use SUM but the formula needs to be "array entered", i.e.
=SUM(SUMIFS(B3:B10,A3:A10,C3:C6))
confirm with CTRL+SHIFT+ENTER

I want to add values from 1 worksheet to another.
The first worksheet ("November 2011") simply contains name & price, names are however duplicated and the sum needs to be added on the second worksheet ("Sales").
e.g. "November 2011"
A B
1 Name Price
2 McDonalds 10
3 McDonalds 10
4 Burger King 20
5 Burger King 30
6 Wendys 5
7 iHop 20
8 iHop 15
The second worksheet ("Sales") contains only 2 columns also Name & Price. However, Name has had duplicates removed.
e.g. "Sales"
A B
1 Name Price
2 McDonalds
3 Burger King
4 Wendys
5 iHop
I need a formula to sum the totals from the first worksheet "November 2011" onto the Price for the second worksheet "Sales".
I have used this formula =IF(ISNUMBER(SEARCH(A2,Sales!A1:A8)),'November 2011'!D2,"") but it only matches the text for a single row.
What I want is a formula which does this:
"Sales"
A B
1 Name Price
2 McDonalds 20
3 Burger King 50
4 Wendys 5
5 iHop 35
Try using SUMIF, which takes the following format:
=SUMIF(<some_range>, <some_critiera>, <range_to_sum>)
In your case, you would put this formula in cell B2 on the sheet Sales:
=SUMIF('November 2011'!$A$2:$A$8,A2,'Nov 2011'!$B$2:$B$8)
Or to make it a bit more flexible by incorporating the entire range:
=SUMIF('Nov 2011'!A:A,A2,'Nov 2011'!B:B)

Without the use of macros or anything fancy, is it possible to write an excel formula that would add up Col-1 rows that correspond to Col-2 rows having the string 'st'?
+----+-------+-------+
+ # + Col-1 + Col-2 +
+----+ ------+-------+
+ 1 + 1 + an st +
+ 2 + 2 + f st +
+ 3 + 1 + st fr +
+ 4 + 1 + bd bd +
+----+-------+-------+
So in this example, it should add up rows 1,2 and 3 and return 1+2+1 = 4
There is a way. Use this: =SUMPRODUCT(ISNUMBER(FIND("st",B1:B4))*A1:A4)
Why do we not just use:
=SUMIF(B1:B4,"*st*",A1:A4)
I'd introduce a third column. The values of the third column will be the one of the first if the second contains the string, 0 otherwise.
Summing up the values in the third column will return the result you want.
If you don't like to display or print the column you introduce you should hide it.
Assuming the first row is in Row 1, starting at column a, you can add another column to the right which checks for each, using this formula:
=IF(ISNUMBER(SEARCH("st", C1)), B1, 0)
That should return 1, 2, 1, 0 respectively for your rows.
Sum that column for the total.
