Calculating Average From Averages

Oct 1, 2013

I have a database with monthly tabs and a summary sheet, on the summary sheet I calculate an average length of stay for each month (tab) but I need to find the yearly average and I don't know if there is a formula that would calculate the true average by using the monthly averages.

Calculating Average Of 2 Averages

Jun 7, 2013

I have a spreadsheet that we are using as a Skills Matrix for the team. The area that the team member deals with is listed in Row 3. The scores for each person are recorded in Columns D to M. The process steps being scored against are in Rows 8 to 38, and are seperated by the area of responsibility.

I am trying to work out the average scores of each person depending on their area of responsibility. I can work out the totals easily enough using:

=IF(ISNUMBER(FIND("CM",D3)),SUM(D11,D12,D13,D14,D18,D19,D20,D23,D24,D25,D26,D27,D28,D29,D30),0)
+IF(ISNUMBER(FIND("V",D3)),SUM(D33,D34,D35,D38),0)

But if I use the same for the average scores is works fine until a person covers two duties:

=IF(ISNUMBER(FIND("CM",D3)),AVERAGE(D8:D10,D12:D17,D19:D22,D24:D30),0)
+IF(ISNUMBER(FIND("V",D3)),AVERAGE(D31:D32,D34:D37),0)

This is becuase it adds the 2 averages instead of working out the total average score. Is there an easy way around this?

i.e. For team members who have CM in Row 3 I need an average of certain cells, for team members who have V in Row 3 I need a different average and for those team members with both CM and V I need an overall average.

Calculating Daily Averages

Aug 9, 2006

The data was taken in 15 min intervals and is organized by date. I have one column with the date and time and another column with the data. I need to find the average for each day. I have almost a years worth of data. Is there any formula I can enter to find the values in a given day and return the average of the values (without having to select the data for each day)? I want to be able to copy the formula down a column with the value per day.

Calculating Averages In Mark Book

May 10, 2006

I want to be able to keep an average grade for my students through the course of a year. Work is marked with a grade A - U. I can use VLOOKUP to convert this to a numerical value but I can't work out how to generate an average from these numbers because every week there will be a new unit of work marked.

On the sample spreadsheet I have attached, the problem I have had is trying to get an average of the numerical values in row 7 because the cells without numbers have a VLOOKUP formula in them and mess up the calculation. And as the range of numbers will increase each time I mark a piece of work I can't use a fixed formula to find the average from say 10 numbers...

Formula: Calculating Averages To Reach A Goal

Aug 27, 2007

Below is my data point for each month. The goal I need to hit is 99%. So I need to figure out what minimum monthly percentage I need for the rest of the year, I will need to reach a goal of 99%, and if I can't reach it, return an error. Lastly, i want to be able next month to go in and fill in the AUG percentage with an absolute number (i.e. 89%) and then I would like the rest of the percentages to automatically update by figuring out the new minimum monthly average given the new value for August. I thought that I might be able to do that if there is a function that says "If cell is a number, leave it alone, if it's a formula, then include that cell in the calculation of the minimum monthly average.

Jan 89%
Feb 88%
Mar 83%
Apr 89%
May 90%
Jun 86%
Jul 82%
Aug
Sep
Oct
Nov
Dec

Goal 99%

Calculating Averages :: Weekly Demand Of A Product

Apr 28, 2008

I am currently using the following formula to calculate the average weekly demand of a product:

=SUM($G8:$CF8)/COUNTIF($G8:$CF8,">=0"))

It works fine, but sometimes the data I'm analysing doesn't span the full horizon (78 weeks). What I therefore want, is for the COUNTIF part to recognise the last populated Cell in the array, and to use the length of the array up to that point to calculate the average. Put another way, if I only have 52 weeks of data (the last populated Cell is $BF8), I want the COUNTIF to calculate based on 52 weeks and not 78 weeks.

Average Of Row Averages

Jan 31, 2012

I want a cell that takes each row in column B and subtracts column A from it... (10-5 for row 1). I want it to do that for all rows and then average that number. This would be easy if I were not using a pivot table with a lot of data.

For example:
Column A Column B
5 10
2 9
6 8
1 4
6 7
1 1

Average From Several Averages

Apr 17, 2007

Column 1 contains the number of times an ad has shown
Column 2 contains the average position of the ad from column 1

Like so,

Ad Impressions.........................Avg Position
Google: 14,220,023..........................3.2
Yahoo: 346,656...............................1.2
MSN: 123,234..................................8.9

Total: 14,689,913............................???


Doing the following,

= Average(B2,B3,B4)

This is not the real average as this is directly influenced by the number of ad impressions...

How can i make a real calculation to give me the true total average position of my ads?

How Do I Create A Running Average That Will Only Calculate The Averages In % Each Month

Mar 20, 2008

I need to do the following and can't figure it out. How do I create a running average that will only calculate the averages in % each month. Example: Opt 1 for Jan, Feb, Mar =1 each= 3 total = 100%; OPt 2 for Jan, Feb, Mar =1,0,1= 2 = 66%; Opt 3 for Jan, Feb, Mar = 0, 0, 1 = 1 total = 33%. My problems is I want monthly running average that shows the yearly percentage up to date but only for the months there is a value 1 or 0. How can this be done because the way I have it now, those % are being divided by 12 and that isn't the correct %

Calculating A Rolling Average

Oct 8, 2009

I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below:
...
C9 39.65 653.95 5.28 163.56 99.56 14.49 ... ...
E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ...
G9 111568 298021 12940 31645 181797 36996 ... ....
...

I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?

Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly

Calculating AVERAGE DEVIATION From A SPECIFIED POINT?

Jul 29, 2009

I have a set of % score values (e.g. 88%, 94%, 82%, 67%)

I would like to know if there is a relatively simple formula that can be used to calculate the AVERAGE DEVIATION from 100%, as opposed to the AVERAGE DEVIATION from the mean, which is what the excel function =AVEDEV will return.

E.g. The Average Deviation from the mean for the the above set of values is 8.25%, whereas the Average Deviation from 100% is 17.25%

I can create a complex manual formula which sums absolute values of the variation from 100% of each score, and then divides by the count total of the number of scores, however this is flawed for several reasons, including the fact it is very time consuming when used across a large set of scores, and it is corrupted when a non score exists in a cell (some of the 'scores' may be '-', in which case they should be ignored and not included in the calculation of the average deviation from 100% by treating as a 0% score (and a deviation of 100% from 100%).

Formula For Calculating Average Time?

Sep 24, 2010

I am trying to calculate the average Talk Time into Minutes and Seconds. Every time I have tried, I get the wrong average.

For example, if I have a total of 53 calls and the total talk time is 4:19:05, what would the average talk per call be? I tried doing everything in seconds (this would give me a total of 15545 seconds) but the total I was getting is 4:89.

What would the formula be to get the correct average time?

Calculating Average Based On Other Criteria?

Feb 27, 2012

I have a series of numbers in the column AB56 going downwards and in AC56 going downwards their respective counts in a data-set.

What I would like to do is find the average of the min and max, the min and max for the average calculation are both determined by looking at the count column, isolating the max, isolating the min, provided they both have a count greater than zero then averaging both results.

eg.

0.1562818960
0.1558039690
0.1553260431
0.1548481172
0.15437019 2
0.1538922643
0.1534143384
0.1529364124

[code].....

In this calculation the MAX is 0.155326043 because it has a count greater than zero, the MIN would be 0.138120697 as it has a count greater than zero, the average of both would simply be 0.1467. i.e. Average(0.155326043,0.138120697)

Calculating Rolling Average Ignoring 0 Values

Jun 6, 2014

What I have is a spreadsheet with a whole bunch of sporting data on it. see attachment for an idea of the layout, Stats.jpg

In these data each round a player is given a rating. What I want to do is calculate is the average rating for each player across the last 3 and 5 games they have played. When a player misses a game they get a rating of 0 for the round. I want 0 ratings to be ignored in the running averages. Additionally, games yet to be played have a 0 in the cell and should be ignored. To get overall averages ignoring 0's was simple I used the averageif function, but I couldn't figure out how to use that but only extract the last 3 non 0 values. I currently have data up to round 12, so if a player has played in 12, 11 and 10 then the 3 round average should just be the average of these 3, but if they missed for example round 11 then the 3 round average should return the average of 9, 10 and 12.

The data is set out in the following way.

In column B I have a list of player names from cells B3:B618.

Across row 1 from N1:AM1 are labels "round 1" "round 2" etc.

The ratings for each player in each round are in N-AM and from 3-618. i.e. N3:AM3 contains the weekly rating for player 1, 4 contains player 2 etc.

I would like the 3 round averages to be returned for each player in column L and 5 round averages in column M.
