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%).

I'm working with a relatively small data set, so in order to better identify outliers I'm looking to calculate the modified z-score. However, in order to do that, I must first calculate the median absolute deviation (MAD). how to do this AND show an example of how to calculate it in Excel?

Looking for a formula to calculate 5 yr avg deviation.
year # of event
2007 59
2008 63
2009 53
2010 42
2011 46
with this set of numbers I can figure out the formula for 5 yr avg but can't figure out how to arrive @ the -18.3%.
where 5 yr avg is 52.6
where 5 yr avg deviation is -18.3%

I'm calculating meter data in 5 min intervals B column is primary meter data C column is secondary meter data B and C are averaged in D using
=AVERAGEIF(B3:C3,">0")
I'm using AverageIf ">0" because one of the two meters is regularly removed from service for calibration, in which case I don't average, I'll only use the online meter reading.
Now I have to figure out how to average B3 and C3 only when the deviation between the two is <10%, and or if >10% to use the greater of the two values.
The examples are B12, C15,18,19...

I'm currently trying to perform some statistical functions on a range of data but with little success.
I want to "AVERAGE" the range and also do a "STDEV" on the range G8:G107 but some of the cells contain #N/A formula errors. I must have the formula returning #N/A to the cells else my chart on the same range plots the empty cell as 0.
What formula can I use that will let me do the standard average and stdev functions on that range, but ignoring the #N/A errors as if they were simply empty cells?

I have tried to find information on this subject, but it seems diifficult to find exactly what I am looking for. I have provided a test example of the operation that I would like to acheive. The first example (Method 1) works well enough but would require defining more detailed functions beyond the scope of average. This would probably be ok, but more importantly, I would like to source particular arrays in this manner for other tasks beyond averages and even standard deviation and am not quite sure how this can be done. In an attempt to describe the situation, I have provided a second example (Method 2). In this example, I am trying to take the average of the jth column array to create an array of averages. I am not sure if I am incorrectly setting up the matrix, if the functions don't perform this way in the matrix, or if this is simply not possible.
Sub test()
a = 5
b = 5
Redim X(1 To a, 1 To b) As Double
'Assumes there is a matrix of values [a x b] drawn from worksheet
For j = 1 To b
For i = 1 To a
X(i, j) = Cells(i, j)
Next
Next
'----METHOD 1---------------------------------------------

I am attempting to calculate Grade point averages for my students for all classes. There are 5 columns of grades to be considered. I frist assign values of 0-5 to the grades then average the points. My problem is that I want the AVERAGE to ignore the zero but it calculates it as well. (I enter a 0 if I have no grade for that class.) I have tried the{ } to make it an array formula but this also did not work. Here is what I have, can anyone help?
=SUM(AVERAGE(IF(AND(L2>89,L2<100),5,IF(AND(L2<90,L2>79),4,IF(AND(L2>69,L2<80),3,IF(AND(L2<70,L2>59), 2,IF(AND(L2>0,L2<60),1,0))))),IF(AND(T2>89,T2<100),5,IF(AND(T2<90,T2>79),4,IF(AND(T2>69,T2<80),3,IF( AND(T2<70,T2>59),2,IF(AND(T2>0,T2<60),1,0))))),IF(AND(AB2>89,AB2<100),5,IF(AND(AB2<90,AB2>79),4,IF(A ND(AB2>69,AB2<80),3,IF(AND(AB2<70,AB2>59),2,IF(AND(AB2>0,AB2<60),1,0))))),IF(AND(AJ2>89,AJ2<100),5,I F(AND(AJ2<90,AJ2>79),4,IF(AND(AJ2>69,AJ2<80),3,IF(AND(AJ2<70,AJ2>59),2,IF(AND(AJ2>0,AJ2<60),1,0))))) ,IF(AND(AR2>89,AR2<100),5,IF(AND(AR2<90,AR2>79),4,IF(AND(AR2>69,AR2<80),3,IF(AND(AR2<70,AR2>59),2,IF (AND(AR2>0,AR2<60),1,0)))))),-1)
I know it is huge. The syntax is correct. It calculates the average, but always for all 5 columns. It will not ignore a 0 in a column.

If I am trying to calculate the breakeven moment from a project that has an initial cost and a series of quarterly returns. This is easy to do visually but I cannot figure out how to arrive at the breakeven point from a data set such as this.
e.g. 50,000 spent at time 0
5,000 received in q1
10,000 received in q2
10,000 received in q3
10,000 received in q4
10,000 received in q5
10,000 received in q6
In which month will I break even?

I am supposed to make an xy scatter graph like the one drawn of paper. The average point need to have a "cross" around it. So far I can just plot the points. I have added the average point as secondary series. I just need to put the "+ sign or cross around" it.

I have XYZ Coordinates for a continuous 3-D line that has numerous segments. I want to input a distance along that line, and have it create the XYZ coordinates at that point. See Image for reference.
Row 2 is my start point - I input the initial coordinates here - this point is the origin of the 3-D line
Column B is where I want the calculated Y value to go for each point
Column C is where I want the calculated X value to go
Column D is where I want the calculated Z Value to go
Column E is the how far along the 3-D line that the (to be calculated) point should be at. (MD1)
Columns G, H, & I are given to me, and I use this data to generate the coordinates in Columns J, K, & L
Column O is the cumulative length of the line at that coordinate. (MD2)
Basically, I had planned on writing a formula to:
Find the coordinates of the point who's MD2 (column O) is before the desired point's MD1 (column E)Find the coordinates of the point who's MD2 (column O) is after the desired point's MD1 (column E)Subtract MD's (column O) to get the length of the segmentFind the distance along that segment that MD1 (column E) fallsUse that distance to traverse along that line to the desired point.

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

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.

I created a pivot table in which sales amounts are represented and a derived table in which market share percentages are showed. Now i am looking for a formula that is able to calculate average market share values. Depending on which country i selected in the pivot table and which category, the number of active companies are changed. How can i formulate this formula to calculate average market share percentages in a certain period. check out my attached file to clarify the situation.

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?

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)

I am trying to find a way to average all the numbers placed in one cell with the answer in another.
So in cell A1
1, 2, 3, 2 or 1-2-3-2
In cell A2 would be 2. But the amount of numbers in A1 will vary from time to time.

i have data on excel which has the following fields:
Invoice No,Inv.Date,Month,Customer,Part Number,Description,Qty.I want my final pivot table to have the following results for every part no. and description
Total monthly sales
total year sales
and for each model sale calculated as sale quantity / week
I have tried the following way but it did not work:
just next to the pivot table under the heading"AVG" i used the following formula to get the sale/week on cell o6=grand total sale /(applicable no. of weeks).and when i am copying the formula to the cells lying below the formula is being applied as that of the first cell so getting the same result for all the rows.is there a way to calculate sale/ wk within the same table

I need to calculate the average of values in a particular column if some other column contains a particular text. For e.g. I would like to calculate average age of all the people who belong to the Comapny "XYZ". Which means that I have two columns here one is "Age" and the other one is "Company". So For all the people who belong to the company "XYZ", I need to calculate average age.
Company Age
XYZ 24
ABC 26
ABC 34
XYZ 30
My average should be (30+24)/2 = 27.

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.

I'm trying to get excel to calculate the average time spent on appointments by officers in a small team. Each of them sees people each day, and as we're very busy I'm eager to get the time spent on each appointment down, by giving them a target of the number of people to see each day. At the moment we gather some stats on this, which show how many people are being seen by each officer.
The attached example sheet shows for one week a list of columns with officer's initials at the top, and says how many people were seen by each person each day during that week and then a how many people overall for the week.
I'd like to be able to generate statistics on the amount of time each officer has spent on average with customers, and base this on the fact that people have 360 minutes per day (they do 6 hours of appointments and another hour for admin) to see people.
I think the spreadsheet attached gives a good idea of the system and what I want to do.
