Having this:
Class Min Max
Alfa 0 16.5
Beta 16.5 18.5
Charlie 18.5 25
Delta 25 30
And this:
Value X
35.52600894
26.27816853
29.53159178
29.84528548
26.77130341
25.07792506
19.2850645
42.77156244
29.11485934
29.5010482
19.30982162
I want a cell to have something like an IF statement (it's got a few more values in it, not this small, it has 8 class). An IF statement this long would probably not work (IF limit of 7) and is an ugly way of doing it. I was thinking of using hlookup, but I'm not sure if that's the best bet.
I can also swap the columns within a table, so I could have "Min| Max| Class"
X values are in a column.
Basically: =IF(X>=0 && X<16.5, Alpha, IF(X>=16.5 && X<18.5, Beta, IF(...
I think you mean VLOOKUP and would be much better way to go.
Make a Ranges sheet like this
Min Class
0 Alfa
16.5 Beta
18.5 Charlie
25 Delta
30.5 Unidentified
In your detail sheet use formula "=VLOOKUP(A2,Ranges!A:B,2,TRUE)" [The True is important]
And you get
Value X Class
35.52600894 Unidentified
26.27816853 Delta
29.53159178 Delta
29.84528548 Delta
26.77130341 Delta
25.07792506 Delta
19.2850645 Charlie
42.77156244 Unidentified
29.11485934 Delta
29.5010482 Delta
19.30982162 Charlie
With your Max range named MaxVal and your Class range named Class, please try:
=IF(A2>30,"",INDEX(Class,MATCH(A2,MaxVal)))
(adjust references to suit).
=MATCH() here is using the match_type parameter of 1: “The MATCH function will find the largest value that is less than or equal to value. You should be sure to sort your array in ascending order.
If the match_type parameter is omitted, the MATCH function assumes a match_type of 1.”
Any X value greater than 30 returns a blank ("") but text may be inserted to suit (eg "Unidentified" instead of "").
The formula could be simplified by removing the error trap, if a row were inserted immediately under the labels with Alpha under Class and 0 under Max. Also by removing the condition, in a similar way.
It is not necessary to specify both bounds of each range.
INDEX/MATCH was chosen rather than say VLOOKUP for reasons as given here.
PS For the Greek *alpha*bet α is usually Alpha.
Edit re clarification
The easiest fix for 25 is Delta rather than Charlie may be to deduct a small amount from each Max value, eg change 25 to =25-1/1E100.

I'm trying to use XLOOKUP to find a value based on user inputs.
The table looks like this:
Type Start End 33 36 42 48
---------------------------------------
4002 1 7 1.17 1.34 1.5 1.84
4002 8 12 1.84 1.67 2.1 3.45
User selects type, number (can be between start and end), and 33-48
I can nest an XLOOKUP to specify the 3 criteria
=XLOOKUP(*type* & *number* , *typeRange* & *numberRange* ,XLOOKUP(*33-48* , *33-48Range* , *ResultRange* ))
And I can find if a value is between the columns
=IF(AND(*number*>=*Start*,*number*<=*End*),TRUE,FALSE)
Can I combine the two? The data is redundant for numbers 1-7, and I would like to keep the table small.
You sort-of can combine them. I have added a couple of extra rows to the table to see what would happen if you had different Type values as well as number values. The problem then is that if you used approximate match and put in a number like thirteen which is out of range, you might end up getting the next row of the table which would be incorrect. One way round it would be to use the options in Xlookup to search for next-smaller-item in the Start column and next-larger-item in the End column and see if the results match:
=IF(XLOOKUP(I2&TEXT(J2,"00"),A2:A7&TEXT(B2:B7,"00"),XLOOKUP(K2,D1:G1,D2:G7),,-1)=XLOOKUP(I2&TEXT(J2,"00"),A2:A7&TEXT(C2:C7,"00"),
XLOOKUP(K2,D1:G1,D2:G7),,1),XLOOKUP(I2&TEXT(J2,"00"),A2:A7&TEXT(C2:C7,"00"),XLOOKUP(K2,D1:G1,D2:G7),,1),"Error")
If you have some checks in place which make it impossible for number to be out of range, then you can simplify the formula:
=XLOOKUP(I2&TEXT(J2,"00"),A2:A7&TEXT(B2:B7,"00"),XLOOKUP(K2,D1:G1,D2:G7),,-1)
or
=XLOOKUP(I2&TEXT(J2,"00"),A2:A7&TEXT(C2:C7,"00"),XLOOKUP(K2,D1:G1,D2:G7),,1)
I've tried a few things on this and settled on a 'cheap' solution. Wanted to know if this can be done directly and more elegantly.
Problem Statement and Sample Data
Assume we have a table in excel with ~200 columns and a large number of rows (~10k).
Sample Data:
identifier
val1
val2
val3
...
val200
ID_1
100
102
34
...
89
We want to add a column at the end that shows us how many "moving average" outliers exist. A moving average outlier is defined as a point that is outside the range (mean - 2 * std deviations, mean + 2 * std deviations), where the mean and std dev is calculated using the previous 10 values (therefore its a moving average outlier).
We will not test the first 10 values. But from val11, the previous 10 values will be used to form the window and we want to test if the value is an outlier.
My Solution so far
I created another table of same dimensions as the original. In cells from val11 (to val200, for all columns), I put in the formula below in the new table. And then, I can simply sum the columns in each row in the new table.
Assume val11 is on X2 in the "shocks" worksheet (for first row):
=IF(OR(shocks!X2<AVERAGEA(shocks!D2:W2)-2STDEVA(shocks!D2:W2),shocks!X2>AVERAGEA(shocks!D2:W2)+2STDEVA(shocks!D2:W2)),1,"")
But if possible, I want to avoid having a second table since it bloats and slows down the file. Any help would be greaty appreciated
I have a formula that currently works pretty well for the most part. It originally was a scoring factor of 90%-100= 5, and 85% to 89.99% = 4 and 80% to 84.99% = 3 and so on. This is represented using the formula below:
=IF($B10>=90%,5,IF($B10>=85%,4,IF($B10>=80%,3,IF($B10>=75%,2,IF($B10<=74.99%,1)))))
So the new requirement came down as follows:
Range value picture
95 to 100% = 5
85 to 89.99% or 101.1 to 105% = 4
80 to 89.99% or 105.1 to 110% = 3
75 to 79.99% or 110.1 to 115% = 2
Less than 74.9 = 1
So the dilemma I'm in is I have not been able to figure out how to create a range for values 2, 3 and 4 to be either or side for the scoring value to become true. So score value 4 should be the ranges of 85% through 89.99% OR 101.1% through 105% to be true.
Does anyone have any ideas on how to restructure this to include the ranges so that if either range is true it would show the correct scoring values? Thanks in advance for your help.
Instead of nested ifs consider using a table then use a VLOOKUP to find the correct value:
I created this table:
Then I can use this formula to get the proper score:
=VLOOKUP(B10,E:F,2,TRUE)
This method has the advantage of being able to easily expand to accomadate new rules. The only caveat is that your table must be sorted on the first column to get the proper return.
I have a data set something like this
Units Price
1 15
100 10
150 9
200 8
50000 7
I need the output as Price with respect to quantity.
Example- If Input value is 90 it should give price as 15
If input is 210 it should give value as 8.
However,sadly I cannot use IF statement.
Thanks in advance.
You can use a combination of INDEX and MATCH
=INDEX(B1:B5,MATCH(lookup_value,A1:A5,1))
This assumes Units are in column A and Price is in column B
Make sure you understand both functions:
INDEX
MATCH - particularly the reason for the ,1) at the end
You can also use VLOOKUP. This is probably a bit easier although INDEX/MATCH is more versatile:-
=VLOOKUP(Lookup_value,$A$2:$B$6,2,TRUE)
I'd like to accomplish the following task. There are three columns of data. Column A represents price, where the sum needs to be kept under $100,000. Column B represents a value. Column C represents a name tied to columns A & B.
Out of >100 rows of data, I need to find the highest 8 values in column B while keeping the sum of the prices in column A under $100,000. And then return the 8 names from column C.
Can this be accomplished?
EDIT:
I attempted the Solver solution w/ no luck. 200 rows looks to be the max w/ Solver, and that is what I'm using now. Here are the steps I've taken:
Create a column called rank RANK(B2,$B$2:$B$200) (used column D -- what is the purpose of this?)
Create a column called flag just put in zeroes (used column E)
Create 3 total cells total_price (=SUM(A2:A200)), total_value (=SUM(B2:B200)) and total_flag (=(E2:E200))
Use solver to minimize total_value (shouldn't this be maximize??)
Add constraints -Total_price<=100000 -Total_flag=8 -Flag cells are binary
Using Simplex LP, it simply changes the flags for the first 8 values. However, the total price for the first 8 values is >$100,000 ($140k). I've tried changing some options in the Solver Parameters as well as using different solving methods to no avail. I'd like to post an image of the parameter settings, but don't have enough "reputation".
EDIT #2:
The first 5 rows looks like this, price goes down to ~$6k at the bottom of the table.
Price Value Name Rank Flag
$22,538 42.81905675 Blow, Joe 1 0
$22,427 37.36240932 Doe, Jane 2 0
$17,158 34.12127693 Hall, Cliff 3 0
$16,625 33.97654031 Povich, John 4 0
$15,631 33.58212402 Cow, Holy 5 0
I'll give you the solver solution as a starting point. It involves the creation of some extra columns and total cells. Note solver is limited in the amount of cells it can handle but will work with 100 anyway.
Create a column called rank RANK(B2,$B$2:$B$100)
Create a column called flag just put in zeroes
Create 3 total cells total_price, total_value and total_flag
Use solver to minimize total_value
Add constraints
-Total_price<=100000
-Total_flag=8
-Flag cells are binary
This will flag the rows you want and you can grab the names however you want.
