Using A Do Loop To Calculate Average?

Jan 17, 2014

I'm trying to understand loops but I'm not making any progress. I'm trying to write a loop to calculate the average of the past 10 Values including the current Value. This is what I have so far.There are also Fields for "Date" and "Time" if that is useful.

[code]
Dim index As Integer
Dim RollAveTotal As Long
Dim CurrentValue As Variant

'There are 4 possible Grades. I only need "Grade 1"

General :: Calculate Average (Blank Vs Zero)

Feb 19, 2013

Currently using a lot of Power Pivot Tables which in part calculate "averages" - but when the data comes form a Query that contains a calculated field using the iff() funtion such as: Outcome: iff(Status = "P", 1,0) we end up with a lot of zeros that create a problem in calcuating a true average. In the following example 2,3,0,1,0,0 the average is "1" but if the zeros were blank the average would be "2" because the blank cells would not be counted.

Is ther a way to have something like: Outcome: iff(status = "P",1,"blank") but what I want is ether 1 or a blank cell, NOT TEXT. If we use "" for the false outcome we still have cells that look blank but are in fact text cells and are counted in calculating average.

Reports :: Calculate Average For Each Column / Expression?

Jul 4, 2013

I have a report that comes from a query with multiple expressions. The expressions look something like this:

IIF([TimeArrive]>[TimeTriage],DateDiff("n",[TimeArrive],[TimeTriage])+1440,DateDiff([TimeArrive],[TimeTriage]))

This works great and my report gives me my columns for each expression in minutes they way it should. Now here is the question...is there a way to insert a text box for each column/expression so I can calculate the Average for each column/expression?

i.e. I want the report to show the average minutes of Expr1 and Expr2, etc at the bottom of each column.

Queries :: Calculate Moving Average - Make Table Query Type Incorrect

Aug 16, 2015

I found the attached example a while back (can't find the site again though ) and it calculates a moving average. I've hacked out the parts I need for my own work and I can create my moving average query without an issue.

However, I need to extract the MA data into a table so planned on using append. I kept getting type errors so I tried make table to see what type it was creating and it appears to be Short Text rather than a number.

I've added an extra button and Make Table query to the example.

As far as I can tell from the code, the moving average value when calculated is a Single. However, when I write it to the table, its a Short Text.

How do I make the created Table use Number Type for my calculated moving average?

Using Access 2013

Average Time In Query

Dec 6, 2005

I have a query with the fields dtDate (Date/Time in Short Date format), NC "Number of Chats" (Long Integer), and TCT "Total Chat Time"(Date/Time in hh:nn:ss format) from tblChats. Each date will have multiple NC and TCT values. This query is totaling them by date with the following SQL.

SELECT DISTINCTROW tblChat.dtDate, Format$([tblChat].[dtDate],'Short Date') AS ChatDate, Sum(tblChat.TCT) AS SumOfTCT, Sum(tblChat.NC) AS SumOfNC
FROM tblChat
GROUP BY tblChat.dtDate, Format$([tblChat].[dtDate],'Short Date')
HAVING (((tblChat.dtDate)>=Date()-7))
ORDER BY tblChat.dtDate;

The query works fine. Now my question.

I would like the query to figure the average time per chat for each day.

Could this be done without VBA? Any ideas??

Thanks.

Average Number Of Sausages Over Time Period

Apr 8, 2008

We sell products out of vending machines and once in every few days (time span between readings may be different every time) read data from the machines using flash drive. Each reading from all machines produces an Excel file:

Reading_Date | Machine_ID | Product_ID | Amount_sold
2008-04-08 | 1 | 1 | 26

The only date that we have is the day on which the data has been read and this tells how many sausages were sold from the date of last reading till the date of current reading (after each reading counters are set to zero).

The problem is to get average amount of product X sold from machine Y on every calendar day. For a total rookie like me it seems like creating another column that would divide the Amount_sold by the number of days between two consecutive readings and put this average amount for every calendar day between these two readings. May it be done this way? How? Another way? How? I would be very grateful if anyone could help me and explain the solution in an accessible way.

Reports :: Average Of Time In Minutes And Seconds

Feb 7, 2014

Basically, I get daily reports from the client and the AHT and ACW values come in seconds. I've recently added code to the query changing the data to nn:ss which works perfectly. Below is some info:

tblTelephony
[AgentName]
[Calls] (number of calls answered)
[AHT] (in seconds)
[ACW] (in seconds)

[Code] ....

The above code works very well, where I'm stuck is in the attempt to average the fields [AHTMinSec] & [ACWMinSec] by Agent in a report.

Using [AHTMinSec] as an example:

I have the daily values for each agent [AHTMinSec] in the detail, Avg([AHTMinSec]) in the Agent group footer showing each agent's average, Avg([AHTMinSec]) in the Team group footer showing team averages and Avg([AHTMinSec]) in the report footer showing the campaign average including all teams. When I run the report the details are hidden providing each agent's average, the team average, and the campaign average.

The report worked just fine until I converted to minutes with the above code. Is there a reason that I'm getting an error stating that the calculation is too complex? I've done enough research to determine that the db can't Sum in order to average...

Calculate Time Difference

Aug 3, 2005

Hello,

I,ve made the following date fields in a form: begintime, endtime. I've also made a field Diff that calculates the difference between the two by the code : Diff = Format([begintime] - 1 - ([endtime], "Short Time").
Bij this code you can calculate the difference even over night.

But now I've got to calculate the part of the time someone worked between midnight and 06:00AM if that person indeed worked in those hours.

e.g. someone started at 16:00 end ended at 03:30. The part of time I need = 3:30
e.g. someone started at 01:00 end ended at 11:00. The part of time I need = 5

How can I accomplish this? I hope someone can help me because I'm :confused:

Thnx Remco

Calculate Time On Report

Oct 5, 2007

I have one table, Leopard Test Scores 2007, that has only two fields, employee and TotalSeconds. The totalseconds column has a "Number" data type with Long Integer. All entries in this column represent the number of seconds and individual spent to take a test.

All I need to do is calculate the total minutes for ALL records in this table for a report. I want the total to come out in this format: HH:MM:SS - so I've added the following three fields to my query:

Hours:[TotalSeconds] 3600
Minutes: ([TotalSeconds] - Hours * 3600) 60
Secs: ([TotalSeconds] - Hours * 3600 - Minutes * 60) Mod 60


However when I add those three fields to my report, I get an "enter parameter value" for hours and minutes. I must be missing something? any suggestions??

Thanks for any help provided!:)

The below function returns correct time difference between workdays. However, it is excluding Saturday as per the code.

It is calculating 06:30 am to 22:00 pm time for weekdays but I also want it to calculate the time from 10:00 to 13:30 on a Saturday.

I am trying to use the NetworkMinutes function to achieve this. However, there is a problem getting the time for Saturday.

Calculate Working Time Between Dates In Access

Oct 26, 2006

I have searched the forum for this answer but no luck. :(

I'm trying to calculate the amount of WORKING time between two dates in an Access database. At the moment i am just subtracting one date from another but this gives me all of the time in between including weekends and evenings.

I need this time to be calculated in hours.

In Excel i know there is a NETWORKINGDAYS function which does something similar but with days rather than hours.

At least if i could get the working days i could then convert it into hours.

Please help!

Need Query To Calculate On Time Deliveries As A Percent

Mar 13, 2006

Hello:

This is for the purchasing guy at my client's office. He has 9 vendors he wants to track their on time delivery performance. The data comes from the purchase order tables in his accounting software, to which I've linked via ODBC.

So far so good. I've created a query to pull only those 9 vendors from his total population, then ask for the date range to query by date for the date range (start and end date), and use an expression to calculate the difference between the date wanted and date received so he can tell if the delivery was on time or not. (ex: date wanted: 3/10/06 date received 3/13/06. 3 days difference = late delivery)

The twist is he wants another field so he can mark whether he considers the delivery late or not depending on extenuating circumstances he keeps locked up in his cranium, despite what the date difference results tell him. So, I created a combo box and he can select "Yes" or "No." If he selects YES, a value of 1 is written to the table in that field, if he selects NO, a value of 2 is written to the same field.

So, I need the query to group by vendor, count the total number of entries for that month by that vendor, count the number of "1"s and express that total as a percent of total deliveries.

To summarize, vendor A had 8 deliveries, 5 were on time, meaning he had a 62.5% delivery score. Vendor B had 10 deliveries, 7 on time, meaning a 70% delivery score.

Sorry for the long winded explanation, but perhaps someone can assist. All help appreciated.

Feb 8, 2014

I have a AS400 database table that stores time in the following manner 70535 (hour, minutes, seconds).

Tables :: Calculate And Store Time From Dates?

Nov 11, 2012

We are collecting data from client files that have multiple dates (start_date, event1_date, event2_date, end_date.) For client protection purposes, we are absolutely not allowed to leave the facility with the actual dates. However, we want to know how many days have passed between each event. I thought about having the data collectors enter each date, have a calculated field store the time between dates, and then have the actual dates cleared when the record is saved or when the person moves to the next record.

SQL Expression - Calculate Difference Between Start And End Time

Jun 2, 2015

I'm trying to calculate the difference between start and end time, which works fine with:

Total Time: DateDiff("n",[tblTaskTimes]![StartTime],[tblTaskTimes]![EndTime])

However, this is for a database that calculates billable time in 10th of an hour. So, for example, 1 hours would be 1, 30 minutes would be .5, less than 6 minutes would be .1.

The format for this expression is set up to a general number, if that matters.

It's gotta be something in the formula like multiplying this by 24 (for 24 hours) and then dividing by something. Nothing I'm trying is working.
