How to rank the position of students based on percentange - excel

I hope you are will be fine.
I am stuck in finding the ranks of students based on percentage.
I have Excel table having multiple columns, concerning columns are Percentage and Position. My data set starts from Row 25 = R25(in excel)
I am using following formula to calculate the percentage of the students based on obtained marks and total marks
=IF(V25="F","",N25/O25)
Where Column V includes pass or fail (in case of fail "F"), column N includes obtained marks and column O includes total marks
It produces the correct output as required:
Now comes to the real problem. Finding the rank/position of student.
I am using RANK.EQ formula to calculate the rank/position of the students based on percentage
=IF(V25="F","Nil",RANK.EQ(P25,[Percentage]))
It also produces the correct output as per formula:
complete pic = >
Now what I want
The two student who obtains 80% marks are ranked as 1 (according to data set)
Now the student who obtains 74% marks should be ranked as 2 instead of 3 and so on
Here is the clear picture of what I require:
I already tried the =SUMPRODUCT(), =MATCH(), =COUNTIF() etc.

Got something I hope you can adapt to your needs. I replied your data this way:
As you can see, formula in column B returns ranking as you wish. To get this,I used an array formula:
=IF(A1="";"";SUM(IF(FREQUENCY(IF($A$1:$A$6>A1;$A$1:$A$6);$A$1:$A$6)>0;1))+1)
NOTE: Because this in an array formula, it must be entered into cell pressing CTRL+ENTER+SHIFT or it
won't work! You will know if you did it properly if your formula shows { at start and } at end.
The trick here is you want to rank your data in descendant order, but excluding duplicates. The array formula first gets an array of values higher than criteria (number in row), and then count how many unique values are in that array. If 0, it means is the highest value, so its rank is 1 (that explains the +1 at end of formula). If count returns 1, means there is an unique value higher than criteria. so its rank is 2 (count of 1 + we add 1 = 2), and so on...
Hope you can adapt this to your needs.
For this I used info shown here:
Count unique values among duplicates

How to find the 3 highest values and respective category for a cell

Here is an example of the data I'm trying to organize:
I'm looking for a way to automatically see the top 3 categories (column) for each Name# (row). The size of the category is determined by the number below the category.
Ideally, I'd also like to see a percentage breakdown (from the total) for each category. For example, in row "Name3" 2 categories make up a significantly larger portion of the total values. However, without this percentage breakdown, the 3 top values would seem to be comparable, when they are in fact, not.
Interested to see how this would all work with duplicate numbers, too.
I've tried Excel's rank function, but this doesn't tell me the categories that have the 3 largest sizes, just the 3 highest values.
With Office 365:
=FILTER(SORTBY($B$1:$H$1,B2:H2,-1),SORT(B2:H2,1,-1,TRUE)>=LARGE(B2:H2,3))
And copy down.
If there are ties it will expand the results to include it. It finds the third highest value and returns everything that is equal to or greater than it.
This approach spills all the results at once (array version). In cell J2, you can put the following formula:
=LET(D, A1:H5, A, TAKE(D,,1), DROP(REDUCE("", DROP(A,1), LAMBDA(ac,aa,
VSTACK(ac, TAKE(SORT(DROP(FILTER(D, (A=aa) + (A="")),,1),2,-1,1),1,3)))),1))
It assumes as per input data the cell A1 is empty (if not it can be adjusted accordingly). Here is the output:
An alternative that doesn't require previous assumption (but it is not really a hard one) is the following:
=LET(names, A2:A5, Data, B2:H5, colors, B1:H1, DROP(REDUCE("", names,
LAMBDA(ac,n, VSTACK(ac, TAKE(SORT(VSTACK(colors, INDEX(Data, XMATCH(n,names),0))
,2,-1,TRUE),1,3)))),1))
The non-array version can be obtained from previous approach, and expand it down:
=TAKE(SORT(VSTACK($B$1:$H$1,INDEX($B$2:$H$5, XMATCH(A2,$A$2:$A$5),0)),2,-1,TRUE),1,3)
Explanation
To spill the entire solution it uses DROP/REDUCE/VSTACK pattern. Check my answer to the following question: how to transform a table in Excel from vertical to horizontal but with different length.
For the first formula we filter for a given element of A name (aa) via FILTER the input data (D) to select rows where the name is empty (to consider the header) OR (plus (+) condition) the name is equal to aa. We remove via DROP the first column of the filter result (names column). Next we SORT by the second row (the first rows are the colors) in descending order (-1) by column (last input parameter of SORT we can use TRUE or 1). Finally, we use TAKE to take the first three columns and the first row.
For the second approach, we select the values for a given row (names equals n) and use INDEX to select the entire row (column index 0), then we form an array via VSTACK to add as first row the colors and use the similar logic as in previous approach for sorting and select the corresponding rows and column (colors).
Notes:
If you don't have VSTACK function available, then you can replace it as follow: CHOOSE({1;2}, arr1,arr2) and substitute arr1, arr2, wit the corresponding arrays.
In the second formula instead of INDEX/XMATCH you can use: DROP(FILTER(Data, names=n),,1), it is a matter of personal preference.

Function to search for specific number and then to further search for the prefix

I have a huge amount of data to process in which 4 points with a related prefix needs to be subtracted from each other.
Data consists of ID and x value
Example
ID = 290.12, 290.03, 290.06, 290.09, 300.12, 300.03, 300.06, 300.09, 301.12, 301.03, 301.06, 301.09
(let's call prefix a "ring number" and suffix time on the clock)
X value = any numerical value for each ID assigned
What I'm hoping to do is to search for the first number before the dot i.e. 300 and then subtract the value of 300.06-300.12 in one cell and in another cell 300.03-300.09.
(The subtraction is just an example, how I need to manipulate with the numbers is slightly more complicated, but I got this one under control)
This is my actual Data and what I need to produce is to the right of the raw data. At the moment, I'm doing it manually for each set of "rings"
Anyone knows how to approach this? I'm thinking vlookup, but I'm not very proficient in excel.
New Excel
I tried vlookup, but I don't know how to construct the formula and I run out of ideas.
Edit:
I found out that REDUCE is no requirement in this case, so it can be shortened to:
=SQRT(SUM(((INDEX(B:D,XMATCH(I3+0.09,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(I3+0.03,A:A),SEQUENCE(1,3)))^2)))
You could change +0.09 and +0.03 to your needs and may reference them using LET() for easy maintaining:
=LET(id,I3,
_id1,0.09,
_id2,0.03,
SQRT(SUM(((INDEX(B:D,XMATCH(id+_id1,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(id+_id2,A:A),SEQUENCE(1,3)))^2))))
Previous answer:
=LET(
id,I3,
_id1,0.09,
_id2,0.03,
SQRT(
REDUCE(0, SEQUENCE(1,3),
LAMBDA(x, y,
x+((INDEX(B:D,XMATCH(id+_id1,A:A),y)
-INDEX(B:D,XMATCH(id+_id2,A:A),y))
^2)))))
This formula looks for the matching value of the id value I3 + _id1 minus the matching value of id value + _id2 for columns B to D and adds the ^2 results per column. Then it calculates it's square root.
You can change _id1 and _id2 to your needs.
To calculate the Delta (as shown) at once you could use:
=LET(id,I3,
_id1,0.09,
_id2,0.03,
_id3,0.12,
_id4,0.06,
x,SQRT(SUM((INDEX(B:D,XMATCH(id+_id1,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(id+_id2,A:A),SEQUENCE(1,3)))^2)),
y,SQRT(SUM((INDEX(B:D,XMATCH(id+_id3,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(id+_id4,A:A),SEQUENCE(1,3)))^2)),
(x-y)*1000)
You can have a column of unique values of the integers and a new column where you reference these values as id and drag down the formula to get your row by row result
In another column you can refer to these columns and sort per the second column using SORTBY()

How can you in Excel total predefined values depending on cell values

I have a spreadsheet with two tabs. The first one contains Vehicle Types and a numeric score value.
Second Tab has like a variety of these vehicle types and what should be the total score. Depending on the vehicle types present in the respective neighbour cell.
See images below for illustration.
Is there a way via formula to get the total, in Column B in sheet 2, of the corresponding numeric values of column a from sheet 1?
For example, as per the illustration B2 in sheet would total 3; whereby in sheet 1 bus has a score of 1 and car 2.
Update:
As per the answer below, I have used the formula;
=SUMPRODUCT(ISNUMBER(FIND(" "&sheet1!A$2:A$4&" "," "&SUBSTITUTE(A4,CHAR(10)," ")&" "))*sheet1!B$2:B$4)
However, I am unfortunately getting zero as the value. Changing the line breaks in column A in sheet2 I am duly able to get the total. Is there a way to do it so irrespective of how the list is presented in the column the total will work?
I think you are after something like this:
Formula in E2:
=SUMPRODUCT(VLOOKUP(FILTERXML("<t><s>"&SUBSTITUTE(D2,CHAR(10),"</s><s>")&"</s></t>","//s"),A$2:B$4,2,FALSE))
If one has O365 you could just use SUM instead since it would auto-CSE the formula.
If you don't have Excel 2013 or later, you could try the following as another option (shorter but not my favourite):
=SUMPRODUCT(ISNUMBER(FIND(" "&A$2:A$4&" "," "&SUBSTITUTE(D2,CHAR(10)," ")&" "))*B$2:B$4)

How do I count the number of unique customers sold to, per sales person?

To get the number of customers sold to by salesperson, my guess is I could either count the number of sales orders per salesperson per unique customer (i.e. not counting more than the first sale per customer)...
Or, count the number of unique customers per salesperson, where at least one sale is present.
I have done some research but I am still not sure which formula to use and/or how to write it. Here are some examples of what I found.

The most efficient formula AFAIK is with FREQUENCY function, similar to my formula suggestion in your third link "count unique values in excel with 2 conditions" i.e. this formula in D10
=SUM(IF(FREQUENCY(IF(B$16:B$21=B10,IF(E$16:E$21>0,MATCH(C$16:C$21,C$16:C$21,0))),ROW(C$16:C$21)-ROW(C$16)+1),1))
confirmed with CTRL+SHIFT+ENTER and copied down to D11
If you want it to work with filtered data try this version
=SUM(IF(FREQUENCY(IF(B$16:B$21=B10,IF(SUBTOTAL(9,OFFSET(E$16:E$21,ROW(E$16:E$21)-ROW(E$16),0,1)),MATCH(C$16:C$21,C$16:C$21,0))),ROW(C$16:C$21)-ROW(C$16)+1),1))
Explanation:
The MATCH function is the crucial part, that will return the same relative row number for repeated values. For your data MATCH function returns the following array:
{1;2;3;3;5;6}
Notice that the repeated 3 corresponds to your repeated customer Smith
The internal IF function returns the MATCH values only for rows where B10 matches (i.e. correct salesperson) and column E > 0 (there's a sale) so for your data the above array becomes this:
{1;2;3;3;FALSE;FALSE}
The first four values are the same as above because those 4 rows match salesman and have sales value > 0, rows 5 and 6 are FALSE because one or both conditions is FALSE
So, for our unique count we need to count the number of different numbers in that array (3)
FREQUENCY does that by assigning that “data array” to the “bins array” returned by
ROW(C$16:C$21)-ROW(C$16)+1
…. which evaluates to the following: {1;2;3;4;5;6}
So when the above data array is distributed into the bins (see FREQUENCY function for help on how this happens) you get this array, finally from FREQUENCY
{1;1;2;0;0;0;0}
[bin 1 gets 1 number, bin 2 gets 1 number but bin 3 gets 2 (the 2 threes)]
Now the external IF function assigns 1 to every non-zero value in that array, and SUM sums those 1s so the result is 3
Where A contains targeted salespersons initials (can be dragged down), B contains range of all initials, and C contains range of all amounts:
=SUMIF($B$4:$B$8,$A1,$C$4:$C$8)

Sort Order formula to alphabetise in Excel

I am currently drawing up a spreadsheet that will automatically remove duplicates and alphabetize a list:
I am using the COUNTIF() function in column G to create a sort order and then VLOOKUP() to find the sort in column J.
The problem I am having is that I can't seem to get my SortOrder column to function properly. At the moment it creates an index for two number 1's meaning the cell highlighted in yellow is missed out and the last entry in the sorted list is null:
If anyone can find and rectify this mistake for me I'll be very grateful as it has been driving me insane all day! Many thanks.
I'll provide my usual method for doing an automatic pulling-in of raw data into a sorted, duplicate-removed list:
Assume raw data is in column A. In column B, use this formula to increase the counter each time the row shows a non-duplicate item in column A. Hardcord B2 to be "1", and use this formula in B3 and drag down.
=if(iserror(match(A3,$A$2:A2,0)),B2+1,B2)
This takes advantage of the fact that when we refer to this row counter in our revised list, we will use the match function, which only checks for the first matching number. Then say you want your new list of data on column D (usually I do this for display purposes, so either 'group-out' [hide] columns that form the formulas, or do this on another tab). You can avoid this step, but if you are already using helper columns I usually do each step in a different column - easier to document. In column C, starting in C3 [C2 hardcoded to 1] and drag down, just have a simple counter, which error-checks to the stop at the end of your list:
=if(C2<max(B:B),C2+1," ")
Then in column D, starting at D2 and dragged down:
=iferror(index(A:A,match(C2,B:B,0)),"")
The index function is like half of the vlookup function - it pulls the result out of a given array, when you provide it with a row number. The match function is like the other half of the vlookup function - it provides you with the row number where an item appears in a given array.
Hope this helps you in the future as well.
The actual reason that this is going wrong as implied by Jeeped's comment is that you can't meaningfully compare a string to a number unless you do a conversion because they are stored differently. So COUNTIF counts numbers and text separately.
20212 will give a count of 1 because it is the only (or lowest) number.
CS10Z002 will give a count of 1 because it is the first text string in alphabetical order.
Another approach is to add the count of numbers to the count if the current cell contains text:-
=COUNTIF(INDIRECT("$D$2:$D$"&$F$3),"<="&D2)+ISTEXT(D2)*COUNT(INDIRECT("$D$2:$D$"&$F$3))
It's easier to show the result of three different conversions with some test data:-
(0) No conversion - just use COUNTIF
=COUNTIF(D$2:D$7,"<="&D2)
"999"<"abc"<"def", 999<1000
(1) Count everything as text
=SUMPRODUCT(--(D$2:D$7&""<=D2&""))
"1000"<"999"
(2) Count numbers before text
=COUNTIF(D$2:D$7,"<="&D2)+ISTEXT(D2)*COUNT(D$2:D$7)
999<1000<"999"
(3) Count everything as text but convert numbers with leading zeroes
=SUMPRODUCT(--(TEXT(D$2:D$7,"000000")<=TEXT(D2,"000000")))
"000999" = "000999", "000999"<"001000"
