Time Efficient Methods For Calculations Based On Different Set Of Data?
May 27, 2014
how to calculate averages and standard deviations based on different time periods without having to manually change the cells?
example:
1st average output at z3, 1st std dev output at z4
data to calculate from c3:c50
2nd average output at z5, 2nd std dev output at z6
data to calculate from c51:c98
3rd average output at z7, 3rd std dev output at z8
data to calculate from c99:c148
and it goes on based on this sequence. i would like to know how to do this without having to change the cells each time i want to calculate. basically what is the quickest way to calculate following this sequence?
I have thousand rows of data in the following format:
Despatched Time Batch Date Time Amended Time
20/4/2013 3:45:00 1 20/4/2013 03:45
[Code] ..........
'Date' is generated by =IF(A2="", "", TRUNC(A2)) 'Time' is generated by =IF(A2="", "", IF(E2 = "", A2 - TRUNC(A2), TIME(LEFT(E2,LEN(E2)-2),RIGHT(E2,2),0)))
And sometimes I may want to change the Time, so I used another column 'Amended Time' to insert a 4-digit value to do so.
I want to arrange them into batches according to the hh:mm, so for the column 'Batch', I used the following formula: =IF(D2 = "", "", IF(EXACT(D2, D1),MAX(B$1:B1),MAX(B$1:B1)+1))
The problem is, when I changed the time by inserting 4 digits in 'Amended Time', the time value is actually different from those generated by TRUNC(), so even two cells have the same time '03:46', the time value is not exactly the same and so they are arranged into different batches (please refer to the following table).
I am having problems with calculations to be performed on date format. As in attached excel sheet, Start Date and End Date can be defined by the user. Once the user enters the dates, year 0 onwards are to be populated with values so that: (Also, not sure if I will need a button to initiate the calculations or a direct function will suffice)
year0 start = Start Date, year0 end = (Start Date +12 months) or (End Date), if End Date is before (StartDate + 12)
year1 start = year0 end, year1 end = (year0 end + 12 months) or (End Date), if End Date is before (year0 end +12)
year2 start = year1 end, year2 end = (year1 end + 12 months) or (End Date), if End Date is before (year1 end +12)
year3 start = year2 end, year3 end = (year2 end + 12 months) or (End Date), if End Date is before (year2 end +12)
year4 start = year3 end, year4 end = (year3 end + 12 months) or (End Date), if End Date is before (year3 end +12)
year5 start = year4 end, year5 end = End Date
If the dates are such that all years 0 to year 5 may not be covered, the years not used should be blank.
I am doing a spreadsheet where I have 1 main sheet and 2 sheets with data.On the main sheet I have a drop down list to select either one of the 2 sheets and upon selecting,all the data from that selected sheet will be displayed on the main sheet.
I am making a time sheet for work. It should be very simple but cant get it to work. I want time in, time out, lunch column, and Total. I don't want a lunch in and a lunch out though just a section where I can put my time in :30 minuets :45 or what ever. I also want it to work. on a 12 hour clock AM/PM .
Here are my column's B2 Is Time In C2 is Time out D2 is Lunch time ( decimal ? ) E2 is the TOTAL with lunch deducted.
the sheet is very long and monitors the sales activities of each individual every day extending vertically down the sheet until the present day.
my first priority was to get the information recorded but now i am wanting to use it. how would an expert arrange this data to make analysis easier going forward?
ultimately i will be wanting to look at individuals, groups of individuals, certain types of activity etc within various time periods.
if you look at attachment, in Cell J2, if cell I2 is greater than 2 minutes but less than two minutes, the I need the value of I2 in Cell J2 otherwise 0:00:00 then K2 between 3 & 4 Mins and so on.
I am compiling a simple worksheet that will keep an ongoing track of labour costs in a production environment. The objective is to end up with a labor cost "per unit" for packing punnets of soft fruit.
The source data I have is;
1 - Start time and end time of the job
2 - Any breaks taken during the job
3 - The number of staff it took to do it
4 - The status of the staff (Supervisor, temp, etc) and their hourly pay rates
5 - The number of punnets packed.
With all of the above it should be a relatively simple exercise to calculate the cost per unit (and with a calculator is!). My problem appears to be that I am not formatting something correctly, because when I try to calculate the costs for the employees' my costs are obviously wrong. I have attached my early draft for reference, in the example shown I am showing that a supervisor earning £7.50 an hour worked for 1 hour 15 mins at a cost of £0.39
I have a start time and a stop time, then a difference is calculated in cell L53. I want to subtract the time value of a break but it only works if the entered value is greater than 1:00. I tried K2-I2-L55 and It works but It wont work for times less than 1:00. I need to be able to subtract :15, :30 or any other value in cell L53.
1st problem concerns entering data as text and it being converted to time. I have found the formula 00:00 which does an excellant job of converting. However, when I want to subtract, (=a2-a1) for example, it treats the time as a number. Sometimes it works, but if the hours are different, say 23:30- 22:10, it will subtract 2330-2210! Is there a way to make this work?
2nd problem, related to the first is when I try to avg a column of times, I get a similar effect.
I am trying to track the time the various activities take. I need this in hours:minutes - Monday through Friday. Attached is the spreadsheet that does NOT work. An "x" in the column creates the timestamp in the adjacent column. Some of my formulas are not correct as the calculations do not create the correct data.
i have a tab on the bottom that is labeled "Man hours 2013" i need to pull the information from this sheet and create a new tab that will pull the property name, how many weeks of service, and the total man hours for each property. i will then be adding a column were i enter the monthly price for this contract divided by the number of weeks we serviced to figure out our percentage of gain/loss.
That leaves the cell null if there is no time in the day... If there is time, checks to see if more than 6 hours... If so, deducts 1/2 hour, else does the difference calculation This does work, but is it the elegant or simple way? recommend?
3) At the bottom of each day totals are calculated by this :
=Text((SUM(E5:E36)),"[H]:mm")
This also works to sum the individual totals to the bottom But is this the best way to work with the times?
4) the individual then inputs the Actual Hours worked by the team... And the sheet does a variance calculation between actual hours Worked vs. Scheduled hours...
=TEXT((D38-D39),"[H]:mm")
Now this is a problem...cannot do negative times....need help!
5) Am having a problem with totaling the individuals weekly total using ...
I need to calculate the total hours worked for a series of 22 locations. Each Location has weekly allocated hours ranging form 0 to 80.
For example: User1 worked 4 Hours on Monday at Location1 and 4 Hours at Location2. User2 worked 4 Hours on Monday at Location1 and 4 Hours at Location3.
I am assuming I will need to use VBA for this calculation.
I am currently working on a rota for my work. What I would like to code is that if a shift begins before 8am and finishes after 2pm it automatically deducts an hour for a lunch break. The spreadsheet currently calculates how long a shift is excluding any calculations for breaks, then checks whether that shift is a normal working day for the staff member, and returns the additional hours the staff member worked on that day. Separately, if possible I would like the spreadsheet to colour code each cell. So if a shift starts before 9am the cell fill color to be red, and if a shift begins after 1:30pm for the cell fill color to be dark red.
I own a Hair Salon which collates its daily takings using a spreadsheet. A section of this takings sheet asks staff to enter which Products have been sold and what they where sold for (RRP), so that once all products have been entered, totals at the end of the day allowing the end -of-day "till-up" process to reconcile purchases and services rendered aginst cash and cheques received.
Unfortunately there is over 600 products to choose from and this evergroes as new products are introduced by manufacturers. Names are long and often very similar, and product price manual listings are slow to reference, therefore the customer has to wait while the staff find the right product and select the right price.
All of this is subject to human error. What i would like is simply to enter part of the product name into a Cell and the right product to be visibly selectable and the price automatically added to an adjacent cell.
Please find attached a daily copy of a spreadsheet that is used to monitor train running times.
The columns on the left - "Serv No, Serv Start Date,Train No:, Scheduled Arrival, Scheduled Depart" are provided to us automatically and the underlying cell formatting/formula cannot be changed. This information is cut directly from a daily report sent to us the previous day. The cell formatting for the start date is custom - dd-mm-yyyy hh:mm.
The sheet is usually locked out with user access only to the left hand side to cut and paste train times in and the input columns on the right hand side. User has no requirement to adjust any details in the left had column apart from to add additional trains at the bottom is need be. I have left the loaded sheet blank and complete with all underlying cell formatting, conditional formatting and formulas intact for you to play with.
Both sheets essentially do the same thing so whatever formula changes are made to the empty sheet can be adapted for the loaded sheet.
For simplicity, I will focus on the empty sheet. What I am mucking around with is having the user input the train arrival time in the "Actual Arrival" column - (column F)
What I am looking at then making occur is the spreadsheet automatically filling the adjacent columns with the appropriate text and calculations.
To do this excel needs to compare column the number (cell input is text formatted) as a number with the arrival time in column G. It then needs to calculate if the train is Early (16 minutes or more before scheduled arrival), on time (+/- 15 minutes either side of scheduled arrival) or late (16 minutes or more after scheduled). It then needs to automatically place the letter "E", "O" or "L" in column K and the time differential in column L.
My problem is two fold.
Firstly, I cannot seem to make the spreadsheet automatically enter a letter into column K depending on the above conditions.
Secondly, I have had limited success in having the spreadsheet compare column J with column F and working out the differential. However, this only works if the time remains linear. IE only if the train runs on time or late. It gives an incorrect time differential if the train is early. I will attach this spreadsheet tomorrow as an add on to this post.
I have a list in Excel with several hundred 8 digit ID numbers in column D. Column C contains the total number of hours the student employee worked. Column E needs to calculate using two different equations depending on if the ID number in column D is a manager's. If the ID number is an employee the total hours worked is divided by 8. IF the ID number represents a manager the total hours worked is divided by 4. I've attempted this by using an array for the manager ID list and also using VLookup without success.
In essence I need to loop through column D, check which type of ID number is present, and then enter the correct formula in column E.
1. I'm trying to show the formula of specific cells in the work sheet. So far I've only found out how to show formulas on the entire worksheet. I imagine there has to be some way of me doing this without using macros.
2. Here's the doozy. What I'm trying to do is use the base code for a formula that is stored in one cell (Formula Page: B5:B7) and apply it to other cells (Calc Page: C4:C6). In other words, I want to apply the cell formula from B5:B7 to the cells C4:C6 and use them to calculate the TOTAL COST. I want it so that whenever I manipulate cells B5:B7, they are also appropriately manipulated in C4:C6.

If I input any FX pair (Column B) without ???JPY in it, then the formula in Column K produces the correct result. Formula is: eg: If Column B = EURUSD pairs and the like: =IF(C3="L",F3-E3,IF(C3="S",E3-F3))*10000.
This formula will produce a +ve or -ve result in points (PIPS) based on the values of E3 and F3. (eg. E3 = 1.2800 & F3 = 1.2750. If C3 = L then the result is -50. Conversely if C3 = S then the result is 50.)
When I input the JPY pairs in Column B, I need the formula to calculate the same way but multiply by 100 (not 10,000). This is because all non JPY cross pairs have 4 decimal places and JPY cross pairs have 2 decimal places. (eg. 1 PIP in EURUSD = .0001, 1 PIP in USDJPY = .01).....
So if Column B = USDJPY the formula would need to be: =IF(C3="L",F3-E3,IF(C3="S",E3-F3))*100 . Have tried many combination's of the IF function but am now starting to think this is not quite the right formula for this situation. Attached is a sample of what I am trying to achieve. The formula would need to incorporate any/all variations in currency pairs as listed in the attached sample.
i've been viewing different formuals, and have to admit there is alot more to excel than I originally thought, and totally stumped as to what and how to go about my problem.
I have a problem, and it mainly stems from my employer not paying me correctly (and pretty much the other 1600 odd employees encounter the same issue too on a semi-regular basis).
To give you a run down, this is our complexed pay system
Mon-Fri, if you work up to 7h36m you get 100%, then 150% until 10h36 and then 200% after 10h36m working time Sat, if you work, its 150% upto 7h36m and then 200% there after Sun, double time all shift But to throw in some complicated things, here are some more items that need to be considered. If you work from one day into the next (say fri into sat, and sat into sun and sun into mon, then after midnight, it then goes to that days rates) If you work your day off, say a weekday, your then paid the eqivelant of saturdays rates unless you were called in straight away which then is sundays rates If you work your day off, say its a saturday or sunday, then its 200% for the whole shift. And then public holidays, its 250% upto 7h36 and 300% thereafter
So as you can see, its pretty complicated, and my employer (a government employer) can't seem to get the right software to pay us correctly, nor can the poor employee sometimes work out if they've been paid correctly or not.
So, this is what I have so far: columns: Day, Type (normal day or work day off or work day off immediate), On1, Sign Off1, Sign On2, Sign Off2, Sign On3, Sign Off3, Working Time, Paid hours (for instance its my normal rostered monday, I start at 12pm, lunch at 5, return at 545 then finish at 915pm, which equates to 8h30m working time and 8h57m paid time) - the 3rd sign on and sign off is if we do extra work beyond our shift.
There are other things aswell like allowances, but thats for another day, and not as urgent as what i'm really looking for.
Now if anyone can understand what i've just written above, your doing pretty good (even some of the most experience employees still don't understan our pay system), and anyone able to produce a formula for what i'm looking for, i'd be exceptionally grateful, and probably the 1600 odd other employees too who seem to get shafted occassionally.
I am trying to display result of risk assessment matrix in excel. I have three columns PROBABILITY , IMPACT and RISK RATING (probability *impact).
Probability = Very Low(1), Low(2), Medium (3), High (4), Very High (5) Impact = Low(1), Medium(2), High(3) Risk Rating = Low (value between 1 -3), Medium (value between 4 - 6), High (value between 7 - 15)
Is there any way that I just use TEXT in the cell (visible to user) and excel does its magic in the background using the numbers that I have for each TEXT? I don't want to display numbers.
Indicate that a user-defined function can only be based upon the calculations that can be placed in a single cell. If you have too many calculations to put them into a single cell, e.g., an entire page of calculations based upon a few starting parameters that eventually yield a single value, then how do you reuse this entire page of calculations?
Is there another Excel mechanism that allows an entire page of calculations to used as a stored procedure?
