Pie chart percentage not calculated correctly by excel. In the picture you can see that the c and d values are exactly the same, but for some reason "c" has a higher percentage denoted to it and I can't figure out why.
The values are a-21; b-5; c-11; d-11; e-3; f-5; g-1; h-39. On the pie chart the percentage received is a-22%; b-5%; c-12%; d-11%; e-3%; f-5%; g-1%; h-41%
While not the ideal solution, if you right click on one of the labels and press the Format Data Labels option, you can change the Number display type to percentage, this will increase the number of decimal places in the percentage shown but give you the accurate result asked for.
The problem is caused by your actual percentages being:
Name Val %
a 21 21.875
b 5 5.208333333
c 11 11.45833333
d 11 11.45833333
e 3 3.125
f 5 5.208333333
g 1 1.041666667
h 39 40.625
As you can see these numbers can't be exactly represented as a (whole number) percentage, the compensations have to be made somewhere. It just so happened that the compensations were made on numbers that should be the same.
Another possible option would be to round your percentage results:
Name Val % Rounded %
a 21 21.875 22
b 5 5.208333333 5
c 11 11.45833333 11
d 11 11.45833333 11
e 3 3.125 3
f 5 5.208333333 5
g 1 1.041666667 1
h 39 40.625 41
The sum of these values is now 99 instead of 96 as in your original, which results in a better graph:
You can do this using the formula =ROUND(num,0) for each of your calculated percentages.

Firstly, we have an array of predetermined factors, ie. V-Z;
their attributes are 3, the first two (•xM) multiplied giving the 3rd.
f ... factors
• ... cap, the values in the data set may increase max
m ... fixed multiplier
p ... let's call it power
This is a separate, standalone array .. we'd access with eg. VLOOKUP
f • m pwr
V 1 9 9
W 2 8 16
X 3 7 21
Y 4 6 24
Z 5 5 25
—————————————————————————————————————————————
Then we have 6 columns, in which the actual data to be processed is in, & thereof derive the next-level result, based on the interaction of both samples introduced.
In addition, there are added two columns, for balance & profit.
Here's a short, 6-row data sample:
f • m bal profit
V 2 3 377 1
Y 2 3 156 7
Y 1 1 122 0
X 1 2 -27 2
Z 3 3 223 3
—————————————————————————————————————————————
Ultimately, starting at the end, we are comparing IF -27 inverted → so 27 is within the X's power range ie. 21 (as per the first sample) .. which is then fed into a bigger formula, beyond the scope of this post.
This can be done with VLOOKUP, all fine by now.
—————————————————————————————————————————————
To get to that .. for the working example, we are focusing coincidentally on row5, since that's the one with the first negative value in the 'balance' column, so ..
on factorX = which factor exactly is to us unknown &
balance -27 = which we have to locate amongst potentially dozens to hundreds of rows.
Why!?
Once we know that the factor is X, based on the * & multiplier pertaining to it, then we also know which 'power' (top array) to compare -27, as the identified first negative value in the balance column, to.
Is that clear?
I'd like to know the formula on how to achieve that, & (get to) move on with the broader-scope work.
—————————————————————————————————————————————
The main issue for me is not knowing how to identify the first negative or row -27 pertains to, then having that piece of information how to leverage it to get the X or identify the factor type, especially since its positioned left of the latter & to the best of my knowledge I cannot use negative column index number (so, latter even if possible is out of the question anyway).
To recap;
IF(21>27) = IF(-21<-27)
27 → LOCATE ROW with the first negative number (-27)
21 → IDENTIFY the FACTOR TYPE, same row as (-27)
→ VLOOKUP pwr, based on factor type identified (top array, 4th column right)
→ invert either 21 to a negative number or (-27) to the positive number
= TRUE/FALSE
Guessing your columns I'll say your first chart is in columns A to D, and the second in columns G to K
You could find the letter of that factor with something like this:
=INDEX(G:G,XMATCH(TRUE,INDEX(J:J<0)))
INDEX(J:J<0) converts that column to TRUE and FALSE depending on being negative or not and with XMATCH you find the first TRUE. You could then use that in VLOOKUP:
=VLOOKUP(INDEX(G:G,XMATCH(TRUE,INDEX(J:J<0))),A:D,4,0)
That would return the 21. You can use the first concept too to find the the -27 and with ABS have its "positive value"
=VLOOKUP(INDEX(G:G,XMATCH(TRUE,INDEX(J:J<0))),A:D,4,0) > INDEX(J:J,XMATCH(TRUE,INDEX(J:J<0)))
That should return true or false in the comparison
I have the data as follows:-
a b c d
5 6 32 12
9 8 16 23
15 8 14 20
I want to check the variance of each column and then have 1 variance for each column. Then I would like to get average of variance across columns & finally reach one number for this entire dataset.
Can anyone please help?
Do you want var and mean?
df.var().mean()
output: 39.083333333333336
intermediate:
df.var()
a 25.333333
b 1.333333
c 97.333333
d 32.333333
dtype: float64
NB. by default, var used 1 degree of freedom (ddof=1) to compute the variance. Id you want 0, use df.var(ddof=0).
I am working in excel and for some reason my sum or count function is not working properly. Or, perhaps I am not using the correct function or in the right way.

IF(SUM(A:A>0),28,"")
IF(SUM(E:E>0),31,"")
I have the above columns, I want the Max columns to show a specific number only if there is data in their respective month column. February has data, so it shows 28. March does not have any data so it shows no max. I need to look at the entire column or at least a large area (row 2 to row 2000).
The issue I am having is that if I do not have a value in the first row, but do have values in later rows, the sum or count function will to recognize that and will return zero.

I have tried both sum and count functions, neither are giving me the results I want. I have also tried making >= 1. I found from StackExchange that someone was having a similar problem and a solution was to change the cell format to a number. That did not work either. Any suggestions?
Per my comment, you could use COUNTA() which checks if a cell is blank.
While it doesn't answer the technical reason SUM/COUNT isn't working, it should work for your intended purposes.
=IF(COUNTA(A:A)>0,28,"")
I have an excel spreadsheet with score and frequency of scores, as such:
Score Count
0 2297802
1 2392803
2 1258527
3 969550
4 818579
5 675646
6 591326
7 598960
8 506268
9 448232
10 414830
11 382808
...
I'm looking for a way to 'bucket' these scores in intervals of (say) 3 and plot them to show the distribution:
Score Count
0-2 5949132
3-5 2463775
...
And so on
I'm using Excel for Mac and I tried defining a 3 interval bin in the Analysis ToolPak but that appears to work only on raw data as opposed to the counts that I already have.
in cells D2 downwards, enter your upper (inclusive) bin limits
in cell E2, enter =SUMIF(A:A,"<="&D2,B:B)-SUM(E$1:E1)
copy E2 downwards
example result:
I have a table with three columns in Excel, a,b and c.
One cell has a numeric value X [say 25], I need to get the value in the c column such that X should be in between min and max column. For X=25 the value in c is "20" since X is between the min and max values for the 5th table row.
I'm looking for a range or between kind of function, but couldn't find a function with either name.

You want to look up in that table of yours which improvement value is correct if some value is "25"; in this case that would mean to match line 5 of your table and return the value 20.
You are looking for VLOOKUP, e.g.
=VLOOKUP(B12;A2:C8;2)
