Is there a way to generate a normal curve from just the statistical values (mean, std dev, etc)? I used the NORMDIST function but have to manually do the x values and it generates what I would descirbe as a "sample" curve. I would like to make one based on user input.

In my data there are two columns, 1) File Size 2) Months and then I have created Bin(months) like 0,6,12,18,24

I want to plot average file size in those Bins. For example I would like to plot what was the average file size in past 6 months, past 6-12 months so on.

I would like to use excel to plot a growth curve. I would like it to plot the points that correlate to my data without connecting them by a line. I would then like to give excel a formula and have it plot that line on the graph.

What I need to do is take that curve and apply it to another data set (Set#2) (1-240) and assign a dollar value ($46-$1) to each positional rank.

A "corner cutting" way of doing it would be an Index/Match to simply carry over the dollar value from (for example) #45 from my Set#1 to #45 in my Set#2. This could work reasonably well with data sets of the same size, but mine aren't always the same size, so I need to apply the curve itself. I

I need some VBA to copy data from one table to overlay another. The source table's columns need to be overlayed on the destination column where the numbers in the first row of each table are a match. I have attached a sample worksheet.

View 5 Replies View RelatedI am doing a budget sheet in Excel for the different expenses accrued by the different classes we offer in our university department (honoraria for guest lectures, tickets to shows or museums, etc.). The sheet is formatted as a table and I have the Total Row enabled at the bottom.

However, we have a reserved budget for different things. For instance, Fall 2013 museum tickets has, say, a budget of $1,000. Fall 2013 honoraria might have a budget of $2,000. I want to be able to filter to see only Fall 2013 honoraria: the totals row will reflect this, but I also want it to automatically tell me how much money is left in that budget (i.e. I want it to know to subtract $2,000 from the totals figure because that is the budget for Fall 2013 honoraria).

It gets a little more complicated because we also have a budget for each class too. One class might have both honoraria for guest lectures and field trips to a museum, and we might say "We don't want this class to spend more than $500." Again, I want to filter to see just this class, and have the Totals row also show me how much money is remaining for this class.

Basically Im crap at excel and need to start learning the in's and outs more but I have drafted up a double sided spreadsheet that I would like to run a series of prints 'inhouse'

I would like it if I could insert an overlay serial number on the sheet that would enable me to carry out future prints adding an incremental number to the serial number EG printing off 100 prints where the serial number runs from

CODA/BL1_00001

CODA/BL1_00100

IS this possible using general tool tricks of the day ie VB, macros or does an add on program exist that will enable this to be generated on a fly between the program and the printer.

I have the following two bar charts. (see links below). I would like to overlay both these bar charts together and obtain the chart shown in link 3.

For example, at 4.4 GHz and 1.8m antenna, two values (downtime/year) are possible 15 min or 557min. This is represented in the third figure Since the first chart contains small values and the second chart contains large values for the x-axis, will I able to change this to log scale for ease of analysis?

I have been searching to see if it's possible to create a histogram with non-numerical data and it doesn't seem like it's possible. Is there something similar where I can. Count number of occurrences of a string and organize them from most frequent to less frequent? There are about 60 possible strings.

e.g.

ABCDEFGHIJ

1ddhykygghd

2jlqqwertya

3ukhghjklzx

4tukyuuiioa

5xypyjkkadh

Then output the counts of each of the strings (letters in this case) present. I was thinking of just putting them in the same row or column and manually counting, but it doesn't seem like it would be that difficult have it automated.

I am writing a macro that finds the prime numbers between to numbers chosen by the user. I want to create a histogram showing the distribution of the primes. I was going to use the Histogram tool in the Data Analysis add-in. My problem is in setting the input range. I do not know how many entries there will be in the input range. How can I write the argument so that it can be "dynamic" I can determine how many entries there are after I determine the prime numbers but I am not sure how to put that info into the Histogram argument.

View 3 Replies View RelatedI'm making use of a histogram to visualize my data. The only problem is that 90% of the data has a value which lies close to eachother but 10% is very different.

For example:

Interval-----Frequency

0-10------5

10-20-----7

20-30-----6

30-40-----0

40-50-----0

50-60-----0

60-70-----0

70-80-----0

80-90-----0

90-100----0

100-110---2

Now the histogram I will obtain won't look very good. Is there a way I can have an interval like 40 - ... which resembles everything above 40?

I'm trying to use the 2007 histogram tool (or frequency) to show me the frequency of data, but my data is in a different form than required for either of these tools. Let me use the following simple case -- to show the frequency of student grades both tools assume I have a list of student's test grades. What if I instead have more than one column, e.g., "grade" and "number students with that grade"??

My application is actually different, but it's still 2 columns, a numeric property and a weighting factor (e.g., fraction of the total).

I've been trying to make this work with Chart Wizard and can't. I gave out 331 surveys and the data in each column is the answer selections for each question on the survey - A,B,C,D,E. I'd like to do a histogram for each column simply with the percentage of people that chose each answer selection.

I am looking for an formula to calculate the bin width for a histogram chart.

I am thinking of creating 50 bins for the chart. The range (max - min) of the data can be from £10 to £5,000,000.

A straighforward formula will be (max - min)/ 50. But I don't want decimal point in the bin numbers.

I am thinking of using Floor/Ceiling function, to round the bin-width to whole numbers, but 10/50, 100/50, 1000/50,..., 1000000/50 all need to round up/down to different scales! for example, I want 100/50 round to 5, 1000/50 round to 50 etc.....I was wondering is there a formula I can use to calculate the bin-width based on the criteria above or similar?

Those "False, False, False, False" parameters to run a histogram, whatever do they mean? Application.Run "ATPVBAEN.XLAM!Histogram", Range("Inputs"), Hist.Offset(0, 3), Worksheets("OutputSheet").Range("Outputs"), False, False, False, False

Through recorded code, I've seen that to create a histogram, the third False is a "True"... but let's say I've already got the blank histogram created. I'm running a simulation (where the inputs range is being updated with every run), and I want the histogram to be filled in at the end of all the runs. What do these parameters have to do with it? Having them all as false, like I've been told, isn't working.

We were working on a set of stock returns using histogram option from the analysis tools. We have not been able to figure out why we have produced two different sets of frequencies over same set of data and one predefined bin range.

Only a few classes present different counts. Can this be due to two different versions of excel were used?

I'm trying to come up with a histogram chart that adjusts Bin Size based on user input. I've come up with the formulas for Bins and Frequency, but am struggling when it comes to charting the data to dynamically update when the user changes Bin Size. How to make the x-axis dynamically adjust with the number of Bins.

I like to make a linear function out of two coordinate pairs.

First Pair (x1,y1) = (Highest Exam Grade, 99) = (H,99)

Second Pair (x2,y2) = (Class Exam Average, Desired Exam Average) =(C,D)

Slope = (99-D)/(H-C) = m

Linear Function = Y-y = m(X-x) = Y-99=m(X-H)

Each student grade would = "Y" i.e. Y=m(X-H)+99

For example. Let's assume that I want to forcast growth from January through December. I know that in January I will have 100 units. In December, I will have 1,000 units. Is there a formula to predict the the units in Feb-Nov (using a normal growth curve)?

I am trying to calculate the equation of a curve which best fits some data. On the x-axis is date and y-axis the readings. The curve is quadratic, so on the chart I am fitting a 2nd order polyomial and displaying the equation. To prove that the equation the trendline gives me is reasonable, I am applying the equation on the x parameter to get the y parameter estimate and looking to see the error between predicted and actual - see attached.

The equation and the output from it are clearly rubbish, even though on the graph the trendline is a reasonable fit - see attached. Has anyone any ideas why? I think it has something to do with using a date on the x-axis but no idea why. Is there a way to correct for this? I also tried using the following I to calculate the coefficients which came up with a reasonable forecast (although linest should only be used for linear data): =LINEST(C3:C15,B3:B15^{1,2,3})
