How To Weight An Average

Nov 21, 2008

I have some aged data, as follows

325days - $225
20days - $2,725
16days - $27,250
11days - $8,175

Now, if I just take the average number of days ((365 + 20 + 16 + 11) /4) I get 93.0days

However, I want to high value days to carry more weight, than the lower value days.

I gave each set of data a weighted score by dividing the value by the total value, i.e.
$225 / $38,375 = 0.006
$2725 / $38,375 = 0.071
$27,250 / $38375 = 0.710
$8175 / $38375 = 0.213

Sum And Weight Average Variable Data

Dec 13, 2008

Hi there, been using this for a number of years now, but never had to post a question - I guess most things are already answered - but this one is a bit more tricky.

I want to calculate a totals and a weighted average based on months from a data set that has duplicate ID's and variable data (attached example).

I would like to calculate the total tonnes by month and the average grade of those tonnes. Using the 'month ID table' as a reference to the 'Raw Data table'.

Is this possible using if and vlookup functions or will require a higher level of programming knowledge?

Exponential Weight Volatility Average

Jul 25, 2006

to write a function that will exponentially weight a series of returns by a certain decay factor.

I have excel spreadsheets that can do this over several columns, like this

series of returns... rtns squared
2.50% =2.50%*2.50%
3.50% =3.50%*3.50%
5.00% =5.00%*5.00%
1.01% =1.01%*1.01%
0.75% =0.75%*0.75%
4.01% =4.01%*4.01%
-2.78% =-2.78%*-2.78%

Weight Chart

Aug 31, 2007

I am trying to create a weight chart, which works in stones, pounds and ounces. My first query is that each time I enter the weight in for each day, I need it to deduct 1ib 4oz from the weight I enter. At present I have seperate columns for stones, pounds and ounces. However, if I try to do a simple lbs minus 4 it doesn't work, because sometimes the pounds are less than four - so instead of taking the stone column down by one and then deducting the remaining pounds, it just puts the pounds columns to -3 or similar.

Also, I would like my table to work out weight lost over a period of time - so, I have my starting weight at the top and then I want my most recent weight to be taken from the starting weight, leaving weight lost - I can't get this to work either. Is there a way to make it so that the calculation uses the most recent weight entry and does so automatically?

If anyone has any solutions to these queries, I would be very grateful...as I have to caculate this for a number of people and it would be much quicker if it did it all automatically upon entering the most recent weight.

Dimensional Weight Formula

Mar 17, 2009

I have attached a sheet that contains a pretty simple formula that helps me figure out the dimensional weight of a shipment. It is just a simple vlookup that returns the proper rate (Column H) depending on DIM Weight and Zone. It works great.

The issue I'm running into is with various exceptions that I need to put into the formula. The criterias that I need to put into the rate formula (Column H) are:

1-If the one of the Length (Column A), Width (Column B), and Height (Column C) is greater than 60 I need to add 7.50 to the the returned lookup value in Column H.

2-The second longest side the Length (Column A), Width (Column B), and Height (Column C) is greater than 30 I need to add 7.50 to the the returned lookup value in Column H.

3-If the grith (2x Column C + 2x Column B) is greater than 130 I need to add 45 to the the returned lookup value in Column H.

I'm working with a few IF formulas but I can't seem to get all of them to work at the same time. Does anyone have any thoughts?

Automating % Weight Calculation

Mar 16, 2008

I have 1 spreadsheet in which I need to calculate the % weight of some numbers. Columns A to G have data I do not need for the calculation.

Column H has the numbers of whose % weight I need to calculate. The problem is that the no. of rows containing the numbers can change from week to week and I am trying to automate the calculation of the % weights.

So I want try to use column G (as a reference) (like go at the bottom of it so I can know how many rows of numbers there are) and then calculate the % weights.

8/3/2008 223lbs

Total 5lbs

I would like use a formula that would subtract my absolute weight loss total day by day in August. Basically, I want the total "cell" to equate to my total weight loss in August. For Example after 8/3/08 the "total cell" should equate to 5 lbs. What formula do I use to do this?

Calculate The Total Weight Of Any Letter

Oct 18, 2009

I cut alphabet letters out of MDF. I need to calculate the total weight of any letter.
I have a program that will give me the area of any shape. In the picture below I have started with the letter “A”. B7 is the over all area. D7 is the small triangle. G7 is the total area minus the triangle D7. H7 is the thickness and I7 is the total volume.

The weight of my MDF I have set at is 850kg cubic meter. That’s set in A3.

I need the total weight of the letter in J7 to be in grams.
The idea is, I put in the areas and set the thickness and it gives me the total weight.

VBA Stuff- Weight Watcher Spreadsheet

Nov 4, 2008

I have a Weight Watcher spreadsheet. I enter the Calories, Fat and Fiber and I get the # of points for that food. Then I keep put those points into the lower part of the spreadsheet where I track what I eat, and Excel does my simple math for me. What I want to do is keep a list of my foods, and their point value in my spreadsheet. I would like to be able to put the food name in Cell A1, the WW points in BI, and then be able to click a button with a macro that takes those two pieces of data and add them to bottom of my food list. I don't have a food list yet, I would assume I can just put it on sheet 2. I then want to be able to use lists in my cells to choose the food in the future. I need to be reminded how to make "dynamic named ranges. Today, I just need to know how to write the macro to copy and paste those two cells in the first open row at the bottom of my food list.

Unable To Set Weight Property Of Border Class

Apr 22, 2010

I am using the following few lines of code:

Code:

Range("A3:L" & ActiveCell.Offset(1, 0).Row).Select
With Selection

.Borders(xlEdgeLeft).Weight = xlMedium
.Borders(xlEdgeTop).Weight = xlMedium
.Borders(xlEdgeBottom).Weight = xlMedium
.Borders(xlEdgeRight).Weight = xlMedium
.Borders(xlInsideVertical).Weight = xlThin
.Borders(xlInsideHorizontal).Weight = xlThin

End With

However am receiving an error: "Unable to set the Weight Property of the Border Class". The odd thing is, I only receive the error on the following 2 lines:

Code:

.Borders(xlEdgeBottom).Weight = xlMedium
'and
.Borders(xlInsideHorizontal).Weight = xlThin

The sheet is not protected, events are disabled, and the range that gets selected changes dynamically based on the number of rows of data in the table, however in this example cells A3:L15 are selected.

Use One Series To Color Weight Another In Pivot Chart

Jan 19, 2013

I have a data set that I'm trying to present in a pivot chart and am wanting to use one series to color code or weight another series in the chart. For instance, let's say I have different product categories and two metrics for each, a profit margin (expressed as a %) and a revenue figure (expressed as $s). I want the height of individual bars to represent the profit margin but have the level of opaqueness represent the revenue figures...ie the more revenue associated with a product the more opaque it becomes.

Shipping Charge Calculator Based Upon Weight To A Worksheet

Apr 15, 2008

I’m trying to add a shipping charge calculator based upon weight to a worksheet. I was trying to do with with VLOOKUP (my first attempted use of this) so I created a second worksheet called ‘Shipping’ which has the weights in column A (Weight) and the corresponding shipping cost in column B (Price). Up to 70 pounds, column A increases in two-pound increments (A2 through A36, 2 through 70 lbs); from 70 through 150 pounds, the increases are in five-pound increments (A36 through A52, 70 through 150 lbs). The total weight to be shipped is derived from SUM(D2:D30), located on the first worksheet called ‘Order’ in cell D32. In cell E32 I have entered this formula: VLOOKUP(D32,Shipping!A2:B52,2).

My problem is if Order!D32 returns something like 4.5, the value for four pounds is the result, while the six-pound charge should be the result. If I round this value up to 5.0, 5.5 or even 5.9, I get the same result.

I know I’m not supposed to guess at what I need to do, but these are my thoughts: 1) I need to modify the VLOOKUP formula to select the next higher value, i.e., so the 6 lb charge is selected for E32 when D32 contains 4.5 lbs, or the 85 lb charge is selected for E32 when D32 contains 82 lbs, 2) I need to add a ROUNDUP function to the SUM formula; this would need to round up to the next even number up to 70 lbs and then in increments of five above 70 lbs. I don’t know if either approach is correct, and in any case, I couldn’t figure out the syntax for either of these.
I’ve attached a sample spreadsheet, Shipping_Charge.xls.

Average Column Of Cells But Ignore Errors And Return Average Of Numbers That Are There

I have many columns like that - where the errors need to show and I need to show an average of the number/values that do appear, ignoring the errors.

Grade Point Average Using AVERAGE IF AND

Sep 1, 2006

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.

However I have a couple of problems with this. Firstly I would like to exclude the value zero from the average. Secondly to also ignore the lowest and highest values.

Example, if the values in the cells are 0,1,2,3,4,5,6,7,8,9,10 then the current result shows 5, by ignoring the 0 and lowest value 1 and highest value 10 the average should be 4.5.
