I have a little problem with a dataset.
My data look like this:
Volume Pressure
Patient 1 31 15
34 35
32 44
Patient 2 34 23
23 23
23 24
I want to obtain a final output of a mean patient that has for each value of pressure and of volume the mean of the pressures/volumes of the two patients.
Volume Pressure
Mean Patient (31+34)/2 (15+23)/2
(34+23)/2 (35+23)/2
(32+23)/2 (44+24)/2
I have no idea how to write this rule, as I don't know how to explicit that I want to repeat this procedure for every patient I have (I have more than two).
Thank you very much in advance!
I think you are making it too difficult. Simply use AVERAGE and drag.
For example, =AVERAGE(B7,B2)
IF you are open to a helper column you can use the following solution.
For the helper column you want to ad a test/sample ID. To keep it simple I used a numbering system starting at 1 and increments by 1 for each successive test. Plae the following formula in a column adjacent to your first patient results and copy down. You can hide this column later for presentation purposes or stick it off to the side if so desired
=IF(AND(A3="",B3=""),"",IF(AND(A3<>"",B3<>""),1,E2+1))
Then lets build a table of results. Column 1 will be your test/sample ID. Column 2 will be your mean volume, and column 3 will be your mean pressure. In the first cell of column 2 place the following formula:
=SUMIF($E:$E,$G3,B:B)/COUNTIF($E:$E,$G3)
Copy this formula down as needed and one column to the right.
Update cell references to suit your needs.
Dont use full column reference if you have other information in the column either above or below your data range.
I am working on a model of charging load of electric vehicle. I am attaching a link to an excel workbook for your better understanding.
Column B contains random time values
Column G to P represents houses and each house can have 1 car. So the each time values needs to be distributed in one column. Now when a car is plugged in, its load stays constant for 3 cells.
I want excel to randomly distribute these cars e.g. 4 cars to 4 houses and leave others blank.
what i can think of is, to assign each time a random house then use IF formula with AND function to match random times with time series and second condition to match random houses with columns 1-10.
the problem i am facing is, the formula gives a value error and only works in the rows with has random generated time in front of them screenshot. I know there is a very small thing that i am missing. please help me find it
Regards
workbook
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(AND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))>=$F6,INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))<=$F6+TIME(0,30,0)),11,""))
The two elements in the AND find the house number in column C and return the corresponding time in column B.
The first element compares the time in F to that time. The second element compares the time + 30 minutes to F (three cells). If it's between those two times, it gets an 11.
The ISNA makes sure that the house in question is on the list. You could also use an IFERROR, but I prefer the precision of ISNA.
Update
If you want the values to wrap around, you need to OR compare to the next day.
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(OR(AND(ROUND($F6,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,30,0),5)),AND(ROUND($F6+1,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6+1,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,30,0),5))),11,""))
That formula structure looks like
=If(isna(),"",if(or(and(today,today),and(tomorrow,tomorrow)),11,"")
This formulas already getting too big. If you triple it for your three voltages, it will be huge. You should consider writing a UDF in VBA. It won't be as quick to calculate, but will probably be more maintainable.
If you want to stick with a formula, you could put the wattage in row 4 above the house number. Then in another table, list the wattages and minutes to charge. So in, say, B12:C14 you have
3.7 120
11 30
22 15
Now where you have 11 in your formula, you'd have G$4 and the two placed you have TIME(0,30,0), you'd have TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0). I re-arranged some stuff to make it more 'readable' (but it's still pretty tough) and here's the final formula
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(OR(AND(ROUND($F6,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0),5)),AND(ROUND($F6+1,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6+1,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0),5))),G$4,""))
In an Excel 2003 spreadsheet, I have the top row of cells calculating the number of days and hours I have worked on something based on data I put in the cells below for each category. For example I enter the time spent on Programming, Spoken languages, house, piano, guitar...etc. The top cell in each category will keep track of and display how many days and hours I spent as I add the time spent for each category each day. I want to evaluate this top row and then list in a "report" (like a pop up box or another tab or something) in order from least amount of time to the most amount of time. This is so I can see at a glance which category is falling behind and what I need to work on. Can this be done in Excel? VBA? Or do I have to write a program from scratch in C# or Java? Thanks!

Unbelievable... I've been scolded for trying to understand an answer and requested to mark this question answered. I don't see anything to do this and could not find anything that tells you how, so I'm just writing it here. MY QUESTION WAS ANSWERED... But thanks anyway...
Consider the following screenshot:
The chart data is built with formulas in columns H3:I3 and below. The formulas are
H3 =INDEX($B$3:$F$3,MATCH(SMALL($B$2:$F$2,ROW(A1)),$B$2:$F$2,0))
I3 =INDEX($B$2:$F$2,MATCH(SMALL($B$2:$F$2,ROW(A1)),$B$2:$F$2,0))
Copy down and build a horizontal bar chart from the data. If you want to change the order of the source data, use LARGE() instead of SMALL().
Alternative Approach
Instead of recording your data in a matrix, consider recording in a flat table with columns for date, category and time spent. That data can then easily be evaluated in many possible ways without using any formulas at all. The screenshot below shows a pivot table and chart where the data is sorted by time spent.
Edit after inspecting file:
Swap rows 2 and 3. Then you can choose one of the approaches outlined above.
Consider entering the study time as time values. It is not immediately clear if your entry 2.23 means 2 hrs and 23 minutes, or 2 hrs plus 0.23 of an hour, which totals to 2hrs, 13 minutes.
If you are using the first method, then all your sums involving decimals are off. For example, the total for column B is 7.73 as you sum it. Is that meant to be 7 hrs and 73 minutes? That would really be 8 hrs and 13 minutes, no? Or is it meant to be 7 hrs and 43 minutes? You can see how this is confusing. Use the colon to separate hrs and minutes and - hey - you can see human readable time values and don't have to convert minute values into decimals.
For reporting I export raw data from a pbx in CSV. There are many columns with data. Relevant for this case is:
Column A: Date of the events (there are many events on a same day)
Column B: Length of the events in seconds
Column C: Date + Timestamp of every event
I filter out all events shorter or equal to 90 seconds,
I am able to adjust the range by changing dates in 2 cells I created for this occasion (start date is in D1 & end date is in cell D2). Without integarting time I use:
=COUNTIFS(B:B;">=90";A:A;">="&D1;A:A;"=<"&D2)
It works like a charm. I select a range in cells D1 & D2 and I automatically get all the events between these dates excluding events shorter or = to 90 sec.
On top of this I need to know how many events / occurrences happen between certain timestamps. For example from November 1st till November 7th I need to know how man events happened between 12:00h and 13:00h, how many happened between 15:00h & 18:00h etc.
Logically I thought that just adding another criteria_range and criteria (in this example column C) would do the trick. Alas adding column C does not seem to work and I have spinned it many ways.
My intuition is that the DATE + TIME format is inadequate, innapropriate for my case.
Column C looks like this: 02/11/2015 21:59:47
Being european, I'm happy with the DD/MM/YYY notation, but it seems that no formula can take account of the TIME and neglect the DATE in front. Remember I already use column A for the dates. Here in column C I am interested in the TIMESTAMP.
Any aideas or suggestions are welcome.
Thank you very much in advance.
PS: I can always split the time from the date using text to column feature. Yet It means I will be formatting the raw exports and I would like to avoid that at all costs so that I can just copy paste new exports in my control sheet without having to do all sorts of formatting.
Without sample data it is difficult to tell whether you are treating the elapsed time as 90 seconds (integer) or 00:01:30 (as true seconds, a decimal portion of 1). Your formula seems to indicate the elapsed time as an integer but it is also wrong in other places (e.g. =< instead of <=) so the only thing for certain is that it is not a working formula. The same goes for determining the time window. Are you comparing it to 12 and 13 as integers or 12:00:00 and 13:00:00 as true time? They are decidedly NOT the same thing.
The SUMPRODUCT function can provide the cyclic processing required to treat a datetime as time only (e.g. MOD(C2:C12, 1)) or as an integer representing the hour of the day (e.g. HOUR(C$2:C$12)).
The formulas in F2, F5 and F7 are,
=COUNTIFS(B:B; ">="&E2; A:A; ">="&E3; A:A; "<="&E4)
=SUMPRODUCT((A$2:A$12>=E$3)*(A$2:A$12<=E$4)*(MOD(C$2:C$12; 1)>=E5)*(MOD(C$2:C$12; 1)<=E6)*(B$2:B$12>=E$2))
=SUMPRODUCT((A$2:A$12>=E$3)*(A$2:A$12<=E$4)*(MOD(C$2:C$12; 1)>=E7)*(MOD(C$2:C$12; 1)<=E8)*(B$2:B$12>=E$2))
If E5 and E6 were 12 and 13 instead of 12:00:00 and 13:00:00 then the formula in F5 would be,
=SUMPRODUCT((A$2:A$12>=E$3)*(A$2:A$12<=E$4)*(HOUR(C$2:C$12)>=E5)*(HOUR(C$2:C$12)<=E6)*(B$2:B$12>=E$2))
I am working with a weather data set. I am particularly interested in two columns which are cumulative precipitation and a date. My question is a simple one, though I am struggling to figure out the solution. Essentially I am wanting to determine days since precipitation. An example of the data is as follows:
WEATHER DATA
Pr Date
40 8/8/2013
40 8/8/2013
40 8/9/2013
40 8/9/2013
41 8/10/2013
41 8/10/2013
In this example, if I know the last day it rained was 8/7, then 8/8 would have a value of 1 (days since precipitation), 8/9 would be 2, and 8/10 would go back to 0. I have multiple dates because of hourly recordings (I trimmed it down for this post). I've been trying to figure it out with conditional if|then statements, but I'm thinking VBA may be more appropriate here. Any help or insight would be greatly appreciated.
Assuming cell C2 to be equal 1 (or start where you wish by adjusting the C2 value), the formula below works in the example you provided. Type in C3:
=IF(A3<>A2,0,IF(B3=B2,C2,1+C2))
Drag the formula down. Explanation:
If precipitation from time i+next is different from i it comes back to zero --> there was rain.
If time i+next is equal i, then it compares the date d+next with d.
If they are equal hold the number of days without rain from previous cell.
If they are not, add 1 day* to the value inside previous cell.
*I'm assuming you have consecutive days from the following sentence:
I have multiple dates because of hourly recordings
