Identifying Peaks In Data
May 5, 2009
I've collected some data from a GPS logger regarding the speed of an athlete. I want to calculate how many sprints this particular athlete undertook during a training session.
Sprinting is defined as a speed of > 20 kph.
One sprint would be the attainment of one peak >20 kph before decreasing below 20 kph.
It's easy to identify the 3 peaks and thus sprints from the xy scatterplot in the attached file, but I'm struggling to find a way to calculate this.

I have a set of data about with approx 7500 cells all contained in one column. The data has a series of peaks that happen, and I need to identify each peak value and place it in a cell. The peak does not occur at regular intervals but they are somewhat regular, as in within 130-230 data points. So, if one could find the first peak in the first 200 cells, identify it and store it somewhere, then look in the next 200, store it, etc. I don't know how to do that in excel.

to calculate the difference between peaks in an excel graph, but i need to do it between every two peaks.. I was just wondering could anyone tell me how to do this with some sort of formula or a vba file
Ive attached a picture. I need to calculate the difference between the blue peaks along the x-axis.

I have raw data from a cyclic test that needs to be refined to generate a simple trend.
The raw data has about 1000 points to each complete cycle and im only interested in the maximum and minium values of the peaks. This would be easy but I am typically dealing with 15 cycles a second and in some instances up to 5,000,000 cycles in one test.
The amount of data is too large to be completed in one file but if done in parts I can then use a formula to reduce the number of max and min peaks chosen i.e. 1 in 100.

I was wondering if excel can auto label peaks and bottoms of a graph? Let me go further:
I have a graph that has one data number for every day of the year (365). This is a natural up and down curve, similar to a stock.
Can excel find the key high and low points? I have attached an example. In it you will see I have quickly labeled the key tops and bottoms. CHART TEST.xlsxCHART TEST.xlsx.
I basically omitted the peaks/bottoms that are very short term and irrelevant.

In column H I have a list of numbers seperated by a space, the number of lines can change. In column L I have a list of numbers which can change either expand or retract.
I would like to check each cell in column H and if any numbers are not listed in column L then it/they should be shown in column G.
Example1 H2 shows 6 11, therefore cell G2 should show 11.
Example 2 H6 shows 5 6 9 11 therefore G6 should show 9 11

I am looking for the easiest way to find duplicate Work Order numbers that exist in 2 separate Workbooks. EX. Workbook 1 Sheet one contains the numbers 1-100 in A1:A100
Workbook 2 Sheet one contains X amount of the numbers between 1-100 located.
somewhere in A:A. For arguments sake let's assume those numbers are 3,6,33,87,99.
What would the formula be to return the values that are in both of the workbooks?

I have small table i would like to create. Now, it can be done manually ( but its be very very time consuming) but im sure of a way using IFs and VLOOKUPs so that the data selection can be done automatically...
so in column 1 i have various valuations from 0 to anything 50mil plus that i need to then separate into 4 different columns based on their size. so column A would have 0 - 250k, column B 251k to 500k, column C 501k to 1million and etc etc...
vals 0-250 251-500 501-1mill
555,000 300,000
150,00 75,000
Please see attached ... testing values 1.xlsx‎

I have attached a sample sheet which deals with property sales data, in reference to a two-part question.
1. If the row has two, or more, rows share the same value in column 'E', it needs to be identified with a 'Y' in Column G. In looking through old threads, this seems possible, though I could not find and answer I could 'bend' to work. If this is possible, can the following be included?
2. If two or more rows share the same value in column 'E', list the identifiers (value in Column A) for the others in Column H, separated by commas "," or slashes (preferred) "/".
ie.
"00370600000700 'NICHOLLS JOHN W & CARLA R 11/27/2000 85000 '260647 W Y '00370600000800" and
"00370600000800 'NICHOLLS JOHN W & CARLA R 11/27/2000 85000 '260647 W Y '00370600000700" or
"'00370500000801 'FRAHM FREDERICK/ERIK/KRYSTYNA 06/17/2004 110000 '288904W Y '00370500000802/'00370500000803"
The sample sheet attached includes 26 rows of data with several 'doubles' and one 'triple' 'duplicates'.
Please note that in the 'real' file, it has slightly less than 200,000 rows and I have seen 'dupicates' up to 40 with the same value in Column 'E'

I am trying to slim down my database results in Excel via MS Query by searching for Part ID's that are numeric (we have parts that also contain letters....I want to weed those out).
In all my searching on the web, I thought the ISNUMERIC() function should be the function for this, but I keep getting an ORA-00904::"ISNUMERIC":invalid identifier....
Is this function supposed to work or is there another function that will do this
This is my SQL statement so far, which works to get parts that are 6 characters long only:
SELECT PART.ID
FROM SYSADM.PART PART
WHERE (LENGTH(PART.ID)=6)
When I change it to this to get parts that are numeric, it gives the error above:
SELECT PART.ID
FROM SYSADM.PART PART
WHERE (LENGTH(PART.ID)=6) AND (ISNUMERIC(PART.ID)=1)

i am trying to work out how to use the rank formula to rank numbers in column B and keep them in unison with Column A.
So Column A has say 5 1's with column B having different scores then continuing under 1 in A is 2 and so on is there a way to continue the ranking formula without manually changing the cell ranges?
so =rank(B1,$B$1:$B$7,1) but can i do that if A =1 and then A=2 etc ?
so if A=1,rank(B1,$B$1:$B$7,1)

I currently have a database that is similar to the example I've pasted below:
TypeDateTimeA10/01/200910:00B10/01/200910:00C10/01/200910:00D10/01/200912:00E10/01/200912:00
As you can see the Date and Time are repeated for several rows. This is how the data I receive comes through as A,B and C refer to a single transaction and D & E refer to another transaction.
Ideally what I would like to acheive is:
TypeDateTimeTransactionA10/01/200910:001B10/01/200910:00C10/01/200910:00D10/01/200912:002E10/01/200912:00
Where Excel can compare the date and times of each row and look for matching rows above and below it and then fill in a column next to it indicating that x number of rows are linked to a single transaction - preferably labelling them in some order to I can tell how many transactions there are.

I am involved in a software conversion that is taking 4 full time folks over 5 weeks to clean up and assign an alpha-numeric sequential number to each vendor, client. Each scrubber is reviewing an excel spreadsheet containing the names, addresses, FID, telephone, etc. of our vendors and customers. This information is being pulled from 2 separate sources. We are assigning a BP # to the main office location and not retiring that one. then we go on to identifying the dups. All dups get a Y to be retired, but if they have a different address then the main one, we place a Y to bring that address over under that BP#.
Ultimately, we end up with 2 systems combined into one dumping all old numbers assigned and giving each vendors, customers, etc. a new BP# that may have muliptple addresses.
How can we assign a alpha numeric number without going through each individual line...over 900,000 of them to do. Key is to identify duplicate addresses and duplicate names. Some names might be RK Electrical or Robert King Electrical but the address will be duplicated usually.

I am trying to write a formula that shows the best grade for each each student and the subject in which
that grade was achieved.
In a previous post i was shown how to identify the highest grade
MAX(IF(A$3:A$34=A7,C$3:C$34))
I hit CTRL, SHIFT & ENTER to activate the formula - Result in column E
However, I also want to identify the subject in which they scored their highest grade in column F
I have two problems
1. I don't know how to write a formula that brings in the subject based on the grade for each student
2. I don't know how to write a formula in case there is a tie (see DAVID L)

So I have a list of integers in col A that is a truncated list from col B. I want to select the units in col B that do not appear in col A. I tried this statement
=IF(A2=B2,A2,0)
Since both lists (A and B) are ordered from smallest to largest this only worked until a value that is not in ColA appears in ColB and then all the cells following = O.

I have a column of cells, of which certain values have the prefix "EmployeeID:". I'm trying to identify the cells containing the prefix by evaluating each cell using activecell.offset and value to no avail. I've also tried to use the selection. find, however the first instance of the prefix is continually selected, and does not move on. I'm assuming that I must use the findnext feature, however I'm not having much success.

I have some data that has names but is not consistant i.e

I want a formula that says, if there is a space after the comma do nothing, otherwise insert a space between.
I have figured out the second part so my formula will look like
=if(some logic to identify a space after the comma ,"",already figured out this bit)

I am trying to develop an IF formula based on 2 variables;
1. The value in column Q = 4
2. The value in column AA is between -10% and 10%
When both are true, it should return a value of "YES" (or "NO" when untrue). I am having trouble with the range part. It could be that the range spans negative and positive integers, but I'm not sure. Here is what I've got at the present time:
=IF(AND(OR(Q2=4),OR(AA2<0.10)),"YES",IF(AND(OR(Q2=4),OR(AA2>-0.10)),"YES","NO"))

I'm trying to identify duplicates with a return of "True" or "False". The attached workbook has column F for results (to read PI2 A if in column L, PI2 B if in column R or Both), but I want to query if everyone in column E is in column L or is in Column R and if so which one.

I want to sort a spreadsheet based on whether any of the numbers '1', '2' or '3' appear in a particular column.
There are 2 particular rows which I care if they have a '1', '2' or '3' in them, let's say row 17 and 18.
I want to create a formula say in row 20 which would tell me if there is a '1', '2' or '3' in the corresponding cells in EITHER (!) row 17 or 18.
An example to clarify:
Cell A17 = 1
Cell A18 = 2
Then Cell A20 would be = 1 because both A17 and A18 have a '1', '2' or '3' .
2nd example:
Cell C17 = 1
Cell C18 = 0
Then Cell C20 would be = 1 because C17 has a '1', '2' or '3' .
3rd example
Cell D17 = 6
Cell D18 = 12
Then Cell D20 would be = "" (Null - no value) because neither D17 nor D18 has a '1', '2' or '3' .
Note: I am looking just for the numbers '1', '2' or '3' not (!) numbers like 11, 12, 13, 21, 22, 23 etc...

I would like to write a macro to examine a range of cells, and over-write some of those cells with a zero.
I want to over write those cells with either a numerical constant, or a formula with only constants, e.g.
"12345" or "= 123+567-(2*5)"
I do NOT want to over write cells that contain links or any functions:
"=page3!a5" or "=sum(a1:b6"

Is there a way in Excel to identifying certain combinations of numbers? If tried every IF statement I know.
I have an Excel with two columns of numbers and I need to identify their combinations.
18
18
18
19
18
19
18
20
18
18
18
20
The combinations 18 and 18 would return a "LOW" message in the third column, the combination 18 and 19 would return a message "HIGH" etc.

I have a list of variables created by a user like this:
BAND ID START END
Band1 06:00 08:59
Band2 09:00 15:59
Band3 16:00 17:59
Band4 18:00 22:30
Band5 22:31 24:29
Band6 24:30 05:59
Seperately I have data from a third party like this:
DATE TIME VALUE
18/05/08 17:22 10
19/05/08 02:15 1
20/05/08 07:14 5
20/05/08 21:36 15
20/05/08 25:43 1
21/05/08 19:15 15
22/05/08 18:26 16
22/05/08 24:59 2
etc.
I need to be able to identify which BAND ID belongs to each TIME in the list so that I can sum the VALUE figures for each BAND ID (e.g. the first time given,17:22, would belong to Band 3). have tried using LOOKUP but I can't seem to get it to work. Additionally, I have a problem with the 30 hour clock. Would I have to stick to a 24 hour clock? This would mean that I would have to find each time from the list that was between 24:00 and 05:59 and allocate it to the previous day because it is important to keep the values that I ultimately derive in the right day of the week.

Our unique identifiers are from SF.com... they have created unique Account ID's.
Comp Name Unique ID
Company A - 5102AA
Company B - 5102Aa
The problem:
Excel does not recognize the capital A and the lowercase a as being different. I need to pull this data out and bounce data across tables for analytics.
The Question:
Is there any way I can get Excel to recognize 5102AA and 5102Aa as being DIFFERENT ID's?

Here is the deal I have 4 columns. Each line gives you the following information:
The Id is the record number, Code_Name is a code for each Fox in the study, date and area is a sub area in a bigger grid. Basically I have an area divided by squares and every time a marked fox enters in one of my squares a new line in the data is created. What I won’t to know is if a fox when in my area of study will return to the same squares or not.
ID
CODE_NAME
Date
Area
Logical
116
SSS1
02-Jan-09
1A1
273
RRR1
02-Jan-09
2A2
2959
BBB1
02-Jan-09
1B1
2959
What I’m trying to achieve is a 5th column were ill get a logical value of TRUE or FALSE if, for each fox in the next available record a fox went back to the same square or not.
So if you check for the fox RRR1 I have 2 records one in 2 of January in area 1A1 and a second in 7 of January in the same area. For the Fox BBB1 you will see that she was always in different areas and for CCC1 she only came back to one square.
The problem is I have over 400 fox’s and 12000 records and I’m trying to get a way of doing it automatically.
