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.

Is there any formula or any way to calculate moving average on access? What I need is to calculate a value based on data from the past 3 months:
I have following structure for example:
Column A ----- Column B -------- Column C
ValueA1 ------- Value B1 ---------
ValueA2 ------- Value B2 ---------
ValueA3 ------- Value B3 --------- =average (ValueB1, valueB2, valueB3)
ValueA4 ------- Value B4 --------- = average (valueB2, valueB3, valueB4)
My main point id how to calculate values for column C.

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

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.

I obtained data for earnings by industry for men and women over time (5 years). I developed crosstab query that showed the average earnings for men and women for the 5 years.
Now I want within this query to calculate the differential between men and womens average earnings and calculate a percentage within this crosstab query. I tried to use Expressionbuilder with little luck.

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?

AS result
FROM Costs;
But get "syntax error (missing operator) in a query expression ..."

I am still quite new to Access and have spend the last two days looking for a solution to an issue but don't seem to find anything that fits. The problem is that I want the three year average of [NIbyA] inserted in [AvgNIbyA]. The years are stored in [FocalYear] (as Date/Time formate) and [TextYear] (as text formate) and [ID] indicates which entity the record belongs to (see below).
UniqueID
ID
TextYear
FocalYear
NIbyA
AvgNIbyA
1020180-19981231
1020180
19981231
[Code]...
Example.accdb
I have been playing around with update queries but can not seem to get the syntax right. The query needs to add NIbyA for year 1998, 1999 and 2000, divide it by 3 (or use Avg() function or something of that sort) and insert the result into the row where [FocalYear] = 13/12/2000. To add to the confusion, it should obviously only add those records that belong to the same ID. Years are from 1998 to 2010 and ID's are random (this obviously means that the rows where [FocalYear] = 13/12/1998 and [FocalYear] = 13/12/1999 will not have an entry).

Is it all possible to create the equivalent of a combo chart in Excel in Access?
What I need is a graph showing a certain dataset as columns but also a line showing the average for that set.
As an example lets take an exercise programme in a school, each child performs a series of exercises every week and data is recorded, to monitor their fitness progression.
Lets say I wanted to show a graph of one particular exercise, with the class students listed along the x axis, and then show the class average for that exercise dataset as a line on the same graph.

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.

What I am thinking of is to have a fairly simple table, as follows:
Date
Supervisor Name
Day type (Sat, Sun or Weekday)
Duty Number (combo box, looked up from a separate small table)
Time Start (auto-completed based on Duty Number)
Time End (auto-completed based on Duty Number)
Target A (which would be a number such as 1.20 or 0.90)
Target B (which would be a percentage such as 85.00%
Result A (same format as Target A)
Result B (same format as Target B)
Restriction (whole number, no decimal places)
Output 1 (percentage)
Output 2 (percentage)
Then have a report that shows each day's data for each day worked, with a set of text boxes at the bottom of the page in the footer area most likely, that show the average of all Target, Result, Output and Restriction fields for all the dates shown on the report.
It would be most likely to be ran for a 7 day period or a 28 day period, but if it could be made able to cope with any number between the dates specified at the time that the report was being pulled, that would be ideal.
Is this possible, and what would the code be to get a field to calculate the averages at the bottom (I presume that this code would have to be different to handle the decimals or the percentages?)?

I have two columns in my report that at the bottom it gives me the following total, as I put below. I am trying to take the two totals that is gives and get the percentage. 1058/3024 = 35%.
=Sum([TotScrwBlank]) =Sum([TotalAmount]) .349 or 35%
1058 3024
I had did the equation as =Sum([TotScrwBlank])/([TotalAMount]), but this is giving me the answer of 46% which is not correct.

I have a report that I'd like to create a scorecard within. The scores will be expressed as percentages. I have 8 categories of tasks, and each category has a differing number of activities within it. When an activity is completed, the user checks a box indicating it is done. So I'd like to calculate the percentage of a category.
I've tried creating a control that has =Abs([Task_1_1_Flag]+[Task_1_2_Flag])/2 in the On Update and On Enter to just calculate the percentage on the fly when the report is accessed, but the field is blank when loaded despite 1 of the 2 checkboxes displaying as checked on the report. The percentages don't necessarily need to be stored in the table, but could be if that's easier.

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...

I have a report with 3 fields in it. I have made the control source for each field an average of the #'s in the field of the query. I only want it to show 1 record but can't seem to figure out how. I've already listed the cycle option to current record, but it still shows the 3 fields repeating over and over... for ex:
Field 1 Label 7.4
Field 2 Label 8.4
Field 3 Label 6.4
Field 1 Label 7.4
Field 2 Label 8.4
Field 3 Label 6.4
And it goes on and on like this... the averages are correct, but I only want to show them 1 time, not repetitively..

I'm having a problem getting a report textbox to display the average value that I want.
Background:I have a DB that tracks student grades. The course is organized into blocks, with several tests in each block. Students can take the same test multiple times, in cases of failure, or if they get rolled back in class. The DB tracks whether or not each test is a retest or audit.
The tests are also weighted. For example, the Geo Quiz could be worth 10% of the grade for a block, and the final exam 90%.
Goal:My report needs to display the class number, student name, block, test, and associated scores; it needs to show the total grade for each block; and it needs to display the student's average grade across all blocks. I need to be able to generate the report at any point in the course, not just after all blocks and tests have been completed.
Setup:Since I want to display the assigned grade, but calculate the weighted grade into the block grade, I set up a query (qryWeightedGrades) to calculate the weighted grade for each test (e.g. Score of 98%, weighted at 10% of block, results in a 9.8 for the weighted grade). When it comes to calculating the block grade, I just sum the weighted scores.
In the report (based on qryWeightedGrades) I have the grouping levels set up for Class#, Student name, then Block; the test name, score, weight, retake info, audit info, etc. appears together on a row.
How to do, get the average of all the block grades. I can't get the textbox in the Student Name group level footer to average the Block grades in the Block group level footer, without getting an error. I've thought of creating another query that averages the block grades for each student, but how to incorporate that into the footer of the Student Name group level.
Here's an example of what I want the report to look like:
Class#: 13010
Student Name: Smith, Peter
Block: WF101 (4 tests in block)
....Test: Quiz1, Score: 95, Weight: 10
....Test: Quiz2, Score: 90, Weight: 10
....Test: Essay, Score: 80, Weight: 40
....Test: Final Exam, Score: 85, Weight: 40
Block Grade: 85
[code].....
Student's average grade: 91.93 <--Getting this # is giving me problems
Class average grade: ##.##

I have a report that counts the number of monthly calls. What I would like is an average of the monthly calls in the report footer.
My total for a particular month is =Count([Date]) and I named the unbound control MonthlyTotal.
This is in the DateFooter section of the report.
I then put an unbound control in the report footer and used the expression = Avg([MonthlyTotal]).
Of course when I changed from design view to report view, it asked me for an input of [MonthlyTotal].
I then tried =Avg([Reports]![qryLetterWritersbyDate]![MonthlyTotal]) and while it didn't ask me for an input, there was nothing in the ubound control in the report footer.
I have search for an answer, but all I find is using a query. Is what I am attempting to do possible? If so, how?

I'm trying to create a query to work out the total amount to invoice based upon some selections. Currently my query looks at the values in several fields (numberOfRollsUsed etc) by taking the value in these fields and multiplying by a fixed amount to calculate the total.
What I would like to add to the query is fixed values based upon some check box selections. So if check box A is selected, add 5 to the total, is check box B is selected, add a further 10, and so on. All fields and check boxes are held within the same table (Job).
Am I being daft or trying to do something in the worst way possible? I'm actually adding this to an existing system so I don't have so many options to completely redesign the system to calculate this in a better way.
