Calculating Averages
Nov 5, 2006I have a database containing values in 16 fields. the fields are filled in over a period of three years. I would like to be able to calculate the average of the last four values entered, regardless of when in the cycle the value is required. I have tryed to use quereies but connot find away to assign the four fields to the expression so that it is the last four values and if four don't exist, avearage what values there are.

Jan 18, 2008Hi,
In my database, I have clients and client hours. I need to calculate average client hours. My total client hours expression is: TTotals: Sum((Nz([SessionHoursCompleted])+Nz([OptionalHoursCompleted]))). I need to divide this number by the number of clients.
Any suggestions ie sum of client number, sum of clients, count of clients.
I've tried these and the results are incorrect.
Thank You
Odd Averages Result From Query
Jun 15, 2007I am trying to calculate the average patients age from 2671 records using this SQL:
SELECT tbl_Customer_Details.DOB, CalcAge([DOB]) AS Age, DAvg("[Age]","qryAvgAge") AS Average
FROM tbl_Customer_Details
GROUP BY tbl_Customer_Details.DOB, CalcAge([DOB]);
why am I getting the result:
68.1131066106
I would have thought that it would have been 68 a whole number, has anyone got any suggestions why this should be.
thanks
Averages For Duplicate Cells
Jan 4, 2006Right, So i've got a table which has records for the Top 40 Music Charts.
I want to be able to find out the averages for each song taken from it's positions in the chart over the weeks:
http://www.playfm.orcon.net.nz/Chart4.GIF
So essentially I get something that tells me
[Lenny Kravits] [American Woman] [24.5]
[Silverchair] [Ana's Song (Open Fire)] [41.1]
and so on...
Any ideas?
Cheers guys,
Alex.
Weighted Averages In A Query
Aug 12, 2005I have developed the following query to summarise a blast design at a mine site.
Pattern Depth m Subdrill Burden Spacing BCM/hole #Holes BCM
1.00 7.00 1.00 3.00 3.00 54 10 540
1.00 7.00 1.00 3.50 3.00 63 10 630
2.00 7.00 1.00 3.50 3.00 63 10 630
2.00 7.00 1.00 4.00 3.00 72 10 720
Now there will be many patterns, the above however only contains one (called 1). Now what i need is the average Depth, Subdrill, Burden, Spacing, bcm/h. In MS Excel I would have following:
Average BCM per hole = Sum of BCM / Sum of Holes
How to do this in Access? Then just to make it more difficult I want to have the average BCM for each different pattern.
Weighted Averages In Sub-query...
Sep 18, 2007Hi there,
once again I have a problem for which I am looking for some hints...
I still have one table, called tblTransactions, which contains security market transactions. For each buy and sell order, respectively it contains one data set with columns Date, Ticker (i.e. the unique identifier of each security), Quantity (positive for buy, negative for sell orders) and Price (at which the trade was executed).
The following code gives me all stocks, which are no longer part of the portfolio since they have been sold out completely for any arbitrarily chosen date (here 1/30/07) together with the date, on which the last position in a certain stock (identified by the ticker) were sold:
SELECT T.Ticker, max(T.Date) AS SellDate
FROM tblTransactions AS T
WHERE T.Date<=#1/30/2007#
GROUP BY T.Ticker
HAVING sum(T.Qty) =0
ORDER BY T.Ticker;
Now it becomes complicated: What I am looking for is a sub-query, which I want to add to the code above and which gives me the weighted average price at which the stocks were bought and sold, respectively if there have been more than one buy or sell transaction.
That is, for the following sample data of tblTransactions...
Date --- Ticker --- Quantity --- Price
01/01/07 --- AAA --- 50 --- $50
01/01/07 --- BBB --- 25 --- $75
01/10/07 --- BBB --- 75 --- $100
01/15/07 --- AAA --- 30 --- $60
01/20/07 --- BBB --- -100 --- $100
01/25/07 --- AAA --- -40 --- $120
01/26/07 --- AAA --- -40 --- $100
...the query I am looking for should give the following result as per 01/30/07:
Ticker --- SellDate --- WeightedAvgEntry --- WeightedAvgExit
AAA --- 01/26/07 --- $53.75 1) --- $110.00 3)
BBB --- 01/20/07 --- $93.75 2) --- $100.00
Notes / how to calculate the weighted averages:
1) (50*$50 + 30*$60) / 80 = $53.75
2) (25*$75 + 75*$100) / 100 = $93.75
3) (40*$120 + 40*$100) / 80 = $110.00
I do not have any clue at all how to solve that problem. I would be very happy for any hint that could lead to the right direction.
Best regards

Averages Query Not Accurate
Jan 18, 2008My database has 8 clients. During a sample date range, between 1/1/05 and 1/1/11, they worked a total of 348 hours. I need to query them for hours divided by client by date range. 3 clients, for instance, worked a total of 162 in the sample date range but the query is dividing the 162 hours worked
by all 8 clients. I need it to divide the hours in this case by 3. Needless to say, these numbers will change when a different date range is inputted but if the expressions are correct...
Currently, to calculate this number I am using this expression :
Averages: Sum((Nz([SessionHoursCompleted])+Nz([OptionalHoursCompleted])))/DCount("IDOC","spise clients_OLD_OLD").
A copy of the query 'Current Average/Total' is attached.
Thank you for your assistance.
Averages From Multiple Colums With Ignored Values
Feb 15, 2007I have a table containing about 120 records of 40 fields containing integer values. The values are 0 (for 'no experience'), 1 - 5 (for evaluation of experience) and 9 (for question not answered). I would like to generate a row of averages for the 40 columns.
Access includes the '0's when using the Avg function. (So 1,0,3,0,1,4 yields 1.5 (1+0+3+0+1+4 / 6) rather than the accurate 2.25 (1+0+3+1+4 / 4)). I can tackle this in two ways: I either convert all zero's to NULLs, as Access will not count NULL in an Avg function call, or I can do each column in a seperate query using a WHERE clause. I also have the problem of screening out the 9's. I'm reluctant to create 40 queries and then another to amalgamate the results as this seems a very silly way to solve this problem. I cannot convert both the zeroes AND the 9's to NULL as to do so would lose valuable data.
Can anyone suggest how I can obtain a full row of averages for the 40 fields, ignoring 0's and 9's?

Queries :: Calculating Three Different Rolling Averages In One Query?
Jun 26, 2013Is there a way to calculate three different rolling averages in one query?
I just inherited a database where someone is using three queries to capture the same information only with different time frames. They were calculating a rolling three month average, six month average, and twelve month average. I would like to combine these queries into one to reduce time spent running reports from the database. All three queries are based on one table. One of the columns in that table is called "Month Start Date". That field shows the first day of the month when a call was entered. I can get the query to tell me the first month in the three month period and the first month in the six month period, but I can't get it to calculate the averages of the calls that fall in those time frames. Here is the SQL for the query I have now. When I try to run this, I get the error message that my formula is not part of an aggregate function.
Code:
SELECT DISTINCT DateAdd('m','-2',(Max([Month Start Date]))) AS ThreeMonthStartDate, DateAdd('m','-5',(Max([Month Start Date]))) AS SixMonthStartDate, Max([Month Start Date]) AS MaxStartDate, IIf([Month Start Date] Between [ThreeMonthStartDate] And [MaxStartDate],Avg([All Call Rate]),' ') AS ThreeMonthAverageCallRate, LIST_WITH_TNC.Device, LIST_WITH_TNC.Model, LIST_WITH_TNC.[Item Num]
FROM LIST_WITH_TNC;
Is there a way to make this work?
Queries :: Top N For Each Combination Based On Group Averages
Jul 16, 2014I need to create a query where in the end, I will have four rows of data based on based on two combinations of WaterSourceType and Crop.
I need the query to bring back the results of the average Top N (lets say Top 10%) for each combination.
I have tried this every which way and I can't seem to get it grouped like I want it. I NEED to have four distinct rows with the average of the ProfitPerBushel for each grouping.
Basically, what this does is show me the average profitablity of the top 10% in each grouping.
WaterSourceType | Crop | ProfitPerBushel
Irrigated | Soybeans | ProfitPerBushel
Non-Irrigated | Soybeans | ProfitPerBushel
Irrigated | Corn | ProfitPerBushel
Non-Irrigated | Corn | ProfitPerBushel
Reports :: Report Is Not Returning Expected Averages
May 9, 2013My database is set up to track call evaluations with 4 fields for number data (S, A/C, C/E and B) each of these have a possible point total. I also have a percentage field to track out of total possible points.When I run my query I get a list of each of the totals for each of the evaluations with the associates names (as expected).I take that query and try to run a report wizard to give me an average socre for each associate. and the system returns averages of 0 or an odd number that does not make sense.when I use the =Avg([fieldname]) process I get an accurate average of the total but can not get it to do a "subtotal" for each associate.

Queries :: Returning Averages For Quality Test Data
Aug 20, 2013I am designing queries to return averages for quality test data.
I have this query that functions as I want it too [URL] .....
It returns the averages of all the values received for different tests for a lot number (the lot number criteria should be filled out as well)
When I want the query to be more specific and average only certain box numbers in the lot (that start with the prefix PB") the query does not return an average for box numbers starting with PB but splits them up, showing an average for PB1, PB2 instead of combining the data for those boxes into a single unified average ...

Calculating Field Specific Averages From Records In Separate Tables
Apr 28, 2014Let's say I have a table sort of like this one: [URL] .... (Table 1)
What I want to do is make another table that references the first table: [URL] ... (Table 2)
I want the cells in the Average field in Table 2 to calculate an average of all the values for records in Table 1 with Color fields that correspond to the Color field in Table 2 (this makes a little more sense if you look at the pictures). I could do this in Excel, but then problems would arise whenever I would add a new entry to the database, or re-alphabetized the data, since Excel math is depends entirely on the positions of cells, and I want these averages to be continually calculated correctly and to change whenever I add related records to the database.
Queries :: Search For Multiple Plot Numbers Preferably In One Parameter Prompt With Comma To Separate Numbers
Aug 12, 2014I'm having multiple problems with my database like things such as -
i'm currently working on the Query 2 - On the Phone database (ignore Query 1) and i want to search for multiple plot numbers preferably in one parameter prompt with a comma to seperate numbers. (this could be a multitude of numbers so i would like to be able to input as many as needed). Also when i do search on this query since the Criteria is a 'Between' Value i would expect everything between the 2 numbers input to show up - but a lot of numbers out of the range show up too - why is this? (The Numbers are like "69 to 136" and they will show up - but 1-69 and 136-170 would too
I would also like to implement the search results from Query 2 into the Form i currently have made but it just opens up a access table when the search is made?
i cannot link my database as it is too big for the server - But here are the Criteria for Query 2:
Plot No - (criteria = Between [Enter First Plot No:] And [Enter Last Plot No:])
Site - (criteria = Like "*" & [Enter Site:] & "*")
Product - (criteria = Like "*" & [Enter Product:] & "*"
The Query is the one im most concerned about , i can live without a form.
Numbers Stored As Text Convert To Numbers?
Jan 10, 2007Ok so in excel I have some numbers that are stored as text. The reason being that they are zip codes and some begin with 0 and excel doesn't want numbers to start with 0....so when I import these into an access field that has an input mask for zip codes...will it convert these correctly since the field is a text with input mask?

Counting Frequency Of Numbers And Comparing To Frequency Of Another Set Of Numbers In Same Row
Oct 28, 2014I have a table with fields like this one but the weeks go all the way up to 52. What I am trying to do is count the number of consecutive zeros and if it is more than five, count how many of the following fields have a number in them and if that number is less than the number of zeros preceding it identify that person.
For example Joe would be identified below because he had 6 consecutive zeros and then he had 5 weeks of numbers immediately following the string of zeros. Bob would not be identified because he had 5 consecutive zeros and then 5 sets of numbers immediately following the string of zeros so the zero frequency isnt higher than the number frequency immediately following.

Numbers And %
Sep 2, 2004The database that I will be referring to in this querstion ws developed to help track interviews at a local helth care facility (dates, times, location, ethnicity, age, state etc.)
I am trying to develop a few queries to pull certain information out this database. Specifically I am trying to pull out information in NUMBER or % format. Currently I can only figure out how to pull out the information that is currently listed. For example: We have had 57 interviews come into the door this month. All of these inteviews are going to different areas and they all are of different ethnic origin and all have an age difference. When I go to query how many total interviews we have had, I am getting names and not numbers. When I try to query how many different ethnicities have been interviewed, I still get names attached to what ethnicity they are.....so on and so forth. What I would like to do is turn these names into statistics or numbers. Is there any way to query this information and get it to come out in number format? The following is an example of different metrics that I am trying to get from this database.How many total out of state interviews per monthThe number of interviews per state per monthHow many african americans interviews peer per month, how many pacific islander interviewed per month, how many hispanic interviews per month........etcHow many internal candidates iterviewed per month/How many external candidates interviewed per month.The information entered into my fields are not entered in a numercial format. They are intered as names, places, dates, times, etc....My question is can I query this information in such a way that I can generate a report that would allow me to view it in numerical formatAny help will be GREATLY appreciated. Thank you soooo much!!!!!
Problem With Numbers
May 4, 2005Hello,I am new here and new to Access.
I have started to build a database that will be for storing the results of horse races.
However my problem arises when inputting the weight a horse carries.
The weight can be input as, for example, 11.12 or 11.00 or 10.10 however whilst I have no problem with 11.12 the other two appear as 11 and 10.1 is there any way round this.
Thanks for any Help
