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.

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.

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?

My database has a crosstab query that counts the number of hits by month. I have two columns that are named "Count of Material"(Frequency) and "Sum of ordered Qty"(Total ordered). I need add a colum to find the Average Monthly Demand by dividing the Total ordered/Frequency/number of months in the query. I have tried everything to make it work but can't.

I have a table with staff in.
I have a table with the start and end of their shifts.
We have four possible locations and four weeks.
So I have four tables for each location.
I have a module that can work out hours and deductions based on time in and out. I built that into a seperate databse working on a one time in and one time out setup.
I want to incorporate the two so I can get the hours worked over four weeks at all locations and divide that by 4 to get the average weekly hours for a staff member.

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.

Here is an explanation of my database and what I am trying to accomplish. The tables and their fields I have in the database are as follows .....
EmployeeT
EmployeeID - Primary Key - Number (not an autonumber because they are county assigned)
LastName - Text
FirstName - Text
EmailAddress - Text
JobTitle - Text
MobilePhoneNumber - Text
Notes - Memo
[Code] .....
All users will interface with a form that will fill in data on the TransactionT table. I would like the data that is being input into the TransactionT.Quantity field to change the data ItemT.ESBuildingQty or ItemT.D3Qty based on which is chosen from StockLocation (they will only be able to choose either "ES Building" or "D3" when inputting the data).
For example, if the stock amount at the ES building of a particular item is 3 and the stock amount of that same item at D3 is 1 and a user inputs that a quantity of 3 of a specific item are taken from ES Building and Added to D3, I want the new values of ESBuildingQty to be 0 and D3Qty to be 4.

I am trying to write a function in an access 2007 query that will calculate the date range for each of my records based on the month-ending date and the In-transit days assigned to each record (excluding any weekend days) (i.e. if the in-transit days number is 5 & the month ending date is 5/26/12 then my date range would be 5/22/12-5/25/12). I want the funtion to calculate the range, I cannot use parameters as each record will have a different range based on it's in-transit days .

Is it possible to set an access database to take a depreciation value of lets say 10.00, and subtract this from the current value every month?
So far my database has a form where you can input the depreciable life, purchase price, current value and total depreciation. However the date and amount of depreciation has to be added manually into a data table for the text boxs to calculate how much it has depreciated and the current value.

I'm trying to show the modal value of a column in a query that only has text in, not numbers. I want to present this in a text box in a report.
My report already has a query as its record source that only shows data for a given year and given month, these are chosen using parameters created in the query. Thus all I need to figure out is how to show the modal value for the column "Categories" on the report somehow.
Here are my parameters:
Query: [Formula Query]
Column: [Categories]
