Display of standard deviation in graphs

Hello,
I am trying desperately to find out how to present standard deviation within adobe illustrator generated graphs. Can anyone please help me with this problem?
p.s
I am using adobe-illustrator CS2 and winXP
tnx

Dear lwo,
You can add two more channels.
One with mittelwert+standardabweichung/2
and one with mittelwert-standardabweichung/2 .
Then configure them to show only symbols and no line.
Color them red and choose a cross as symbol.
Be sure, the mittelwert channel is the first one in the array,
or the bars will hide the crosses.
Best regards,
Stefan Heinzl

Standard deviation in graph (bar chart)

Dear Community,
I am looking for a solution for my measurement analysis software, programmed in LabVIEW 8.5:
I have an array (1D, double) with some data. This data is shown in an graph as a bar chart (attachment 1 & 2).
Aditionally, there is an other array (also 1D, double) with the standard deviation of my data in the upper array (both calculated via standard deviation and variance VI)
How can I integrate this standard deviation in my graph to be shown as (colored) error bars (attachment 3)
Thanks for your help!
Best regards,
Iwo

Standard Deviation in Graph

Does anyone know how insert standard deviation into a bar graph??
Thanks.

Ah. The key point that I was missing was that this works (for points or bars) only when the series is selected in the graph. Otherwise the boxes are not enabled.

Adding standard deviation bars to graphs

I have composed a bar graph on numbers, and have already calculated the standard deviation of my data. How do I add the standard deviation lines to each bar on my graph? Thank you.

Details available in *_Numbers User Guide_*, page #148 in the English version.

Standard Deviation

I was wondering how you get the standard deviation to show up on the graph. I know where the button is to activate the standard deviation for a simple bar chart, however it doesn't show the actual deviation, it gave me uniform for each bar in the chart. How can I fix this? Also I know that the standard deviation isn't the same because I have seen what the chart I am making is supposed to look like.

cgord,
The problem is that Numbers doesn't know what your chart is supposed to look like. It's doing the best it can. There is no such thing as a standard deviation for a single point. Numbers considers that your series is a data set and calculates a mean and standard deviation for the set. It then applies this mean and deviation to the error bars, in a proper way, the same for each member of the set.
If your data set is actually a collection of dataset averages, each with a standard deviation of its own, then it might be appropriate to show each bar with it's own custom error bar, calculated elsewhere.
To make this work, you would display each bar's corresponding StdDev in the same row as the mean you are charting and then you would indicate to Numbers which column this custom error bar data is located.
Hope this helps.

I need to chart a standard deviation of a moving average in Numbers

In order to complete my statistical analysis of a large ammount of performance data- I was to graph a +/- 2 standard deviation of a moving average AS A SHADED region on my charts. I tried to do this today for Four hours. HELP! PLEASE and thank you SO Much!

You stated:
I have the above charted with the $ values of gains
BUT IT LOOKS LIKE THIS. "
implying it is not correct. Since I don't understand what you are trying to do in general terms I don't know what the problem is.
Can you post some of the data (at least the set you are showing) so we have something to work with?
I made a graph like this:
But since I don't really understand what you want I don't know if this is correct or not.

Help on standard deviation please

I am writing a program to find standard deviation. Below is what I have so far "not much I know" but I have tried so don't get flame happy. It errors out and I have tried to fix it. I know the formula for standard deviaition but I can't seem to program it right. I also need to program the code to have three methods the main, an Average method, and a standard deviation method. I know how to make a method but I am having trouble on how to call them. Any help would be appreciated. I am not asking anyone to do my work for me just give me some tips. I would rather take a 0 on the assignement and learn later than turn in someone else's work becaue I will never pass my final if I do that.
import java.text.*;
import javax.swing.*;
class StandardDeviation{
     public static void main(String [] args){
     DecimalFormat df = new DecimalFormat("0.00");
     //Average Code Segment
          double [] values = {10,20,30,4,2}; //Assigns numbers to values
          double valueAverage,square, sum = 0;
          for(int i = 0; i < values.length; i ++){
               sum += values;
          valueAverage = sum / 5; //Computes Average
          System.out.println("Average is: " +valueAverage); //Displays average of values to test to see if it worked
//Deviation Code Segment
for (int i = 0; i < values.length; ++i)
double diff = values - valueAverage;
sum+= diff*diff;
System.out.println(+ Math.sqrt(sum/(values.length - 1))); // here I was trying to test to see if my formula worked
I get the following error
java:20: operator - cannot be applied to double[],double
double diff = values - valueAverage;

Okay this code works. Duffymo can you give me some pointers of writing this code using multiple methods? I can write the methods. I just have a hard time grasping the concept of calling them. I have had a hard time learning this in java. I also looked at some of your past posts on Standard Deviation I see what you are saying about the multiple methods. I know that I need a main method that would probably include the values. Then I would have a average method which would call the values to compute the average. Then I would have the StdDev method to compute the Standard deviation method. Any tips on where to begin on this?
mport java.text.*;
import javax.swing.*;
class StandardDeviation{
     public static void main(String [] args){
     DecimalFormat df = new DecimalFormat("0.00");
     //Average Code Segment
          double [] values = {10,20,30,4,2}; //Assigns numbers to values
          double valueAverage,square, sum = 0;
          for(int i = 0; i < values.length; i ++){
               sum += values;
          valueAverage = sum / 5; //Computes Average
          System.out.println("Average is: " +valueAverage); //Displays average of values
          //return valueAverage;
     //Deviation Code Segment
for (int i = 0; i < values.length; ++i)
double diff = values[i]- valueAverage;
sum+= diff*diff;
System.out.println("The Standard deviation is: "+ df.format(Math.sqrt(sum/(values.length - 1))));

What I was thinking was that mean() would be a lot more useful if
(1) you passed it an argument saying what test you were interested in. This would
take the place of "column" in your code.
(2) it returned a double value which was the mean of the given test. The snippet you
posted is OK, except that it should return a double not an int. Ie it should look like:    /** Returns the mean for a given test. */
public double mean(int column) {
    double mean = 0.0;
    // do calculation
    return mean;
}Of course if you do this you will have to change how mean() is used from within main().
Instead of a simple "m.output += "\nMean: " + m.mean();" you will need a loop:    // start the string
m.output += "\nMean: ";
for(int ndx = 0; ndx < tests; ++ndx) {
        // append each mean
    m.output += " " + mean(ndx);
}The standard deviation method will be very similar to the mean() one, and
used in a similar way:    /** Returns the sd for a given test. */
public double mean(int column) {
    double sd = 0.0;
    // do calculation based on what was posted,
    // or what you have been told to do.
    return sd;
}

Standard deviation MCXD

Dear all
              We have marked MIC as SPC characteristics and results are recorded for same
now we are not getting standard deviation and cp and cpk value in report as it is standard report it should show below value
if there some setting required plz suggest.

If you run the report and you are seeing something like *** then I suspect it is for the following reason which is provided by SAP in the F1 help if you click on the Cp value field after displaying the report. A
From SAP F1 help:
Note
If there is neither a master inspection characteristic, nor an
    inspection characteristic in the drill-down, the cp value does not have
    an influence. In such a case, the system issues asterisks (***) instead
    of the cp value. Similarly, if there are no tolerance limits, the system
    issues asterisks (***) instead of the cp value.

Query designer and Standard deviation result rows

Hello everyone,
Here is my problem.
I have a key figure for which I do not want any decimals. So in the Number Format : Number of Decimal Places = 0.
I thought the result rows would follow the same rules by not displaying any decimals.
But using the Calculate Result as ... "Standard Deviation", even though my key figure is define with no decimals, the result row displays 5 decimals anyway !
Why? and is there any way I can suppress the decimals of my results rows with a Standard Deviation
Thx
JBF
Edited by: Jean-Baptiste Faubert on Jan 16, 2008 2:56 PM

Hello Jean,
First I would try to unmark flag 'Use default Settings' below Number of Decimal Places in Query Designer.
If this doesn't help you could set Decimal Places in the Provider specific Properties in Key Figure of the MultiProvider used from 'Not defined' to 0.
Also you could change the number of decimals in InfoObject maintainance of used Key Figure (in RSA1).
But then you have to check other queries where this Key Figure is used.
Kind regards
Klaus

Is it possible to display the standard function keys in screen painter

Hi ,
I design a screen in se51 where I use push buttons and input/output buttons and so on in the layout, here in the layout or in my final output screen(when i assign this screen to a transaction) I would like to display other standard keys, ie the function keys and application toolbar items. I would like to know whether there is a possibility to do this , if yes then how?
In a menu painter there is a possibility where I can customize the keys or I can use the standard keys by going to se41 extras->adjust template. Is there similar possibilities in the screen painter.

Ok I see. I should use &var.

Why the timetable cannot be displayed correctly in the Gantt graph?

Hi, jdev 11.1.2.3
Have a table(task_list) with fields as: id,type, title, content,begin_date,end_date,status...
and set EO/VO for the table, and drag data control of TaskListView1 Into a jspx page to create Project Gantt as:
Task id*:id,
Task type :type,
Start Time*: BeginDate,
End time*: EndDate,
And select all table columns.
After running, the page showed a Gannt graph with all fields displayed on the left panel (the begin_date,end_date have values of different dates),but blank on the right timetable panel, what ever the timetable's view (week,month,year,project) will be chosen.
Why the timetable cannot be displayed correctly in the Gantt graph?
Thanks.

Making a Bell Curve in Numbers or MS Office for MAC: I already have mean and standard deviation

I hope my question is a simple one with a simple answer: I have the results of a mid-term and the professor gave us the mean and standard deviation of the results of the exam from which he based our grades. I am a visual person and (to be honest) without having to put forth a lot of effort, I would like to see visually where I fall on this, admittedly, artificial curve. I have both Numbers and MS Office on my MacBook Pro. Is there an easy way to create a bell curve using these numbers? It seems like there should be since those are usually the only numbers needed. I just, honestly, don't want to do the tedious work myself.

Statistical functions including several which deal with normal distribution, are discussed in Chapter 10, Statistical Functions, of the iWork Formulas and Functions User Guide. This useful guide may be downloaded via the Help menu in Numbers '09. Go to chapter 10, or for a direct route, search 'normal distribution'
For what it's worth, you can find the formula for calculating the coordinates for the bell curve here: The-Normal-Distribution-Or-Bell-Curve

Barry
