Hi ,
How to use the Prod Function in a list of averages to find the lease common
value !
here is an example.

AVRG
26.27
-------------------
29.27
25.61
26.17
25
25.32
--------------
3 | These are a list of Over and Under values of the above
-0.66
-0.1
-1.27
-0.95
--------------
3 | These are a list of compile Positive and Negitive values
also average

| trying to locate which one is within range of the
average,one group
-0.745
| is always known ,in this case it's (25) of the above
values,which now leave (4) items to be measure by an average, maybe if I
could find the Standard Error in the Averaging,it would help in locating(plus
or munis) and the amount !

Thanks in advance


Joseph..

Is this what you want?

B2=Average=26.27, C2 =stdev=1.729 on your data

The standardize function is STANDARIZE(x,Average,Standard deviation)
x=29.27 results in 1.7325649

Use this formula to find the x using goal seek. (Tools, Goal seek)

Enter 30 in say g1, In g2 type =standardize(g1,29.27,1.7325649)

In gaol seek Set cell = the formula (g2) in the change cell type 1.745 the
by changing cell is g1 Repeat and set change to -.745

These result in values of 28.86784223 and 24.98572503

Hi Peter,
and thanks for the reply.
Maybe that I am not explaining myself good enough to be understood here!
The example that I posted was all average results,and decribled as positive
and negitive category,which mean I am try to predict a fluctuation of the
(Arithmetic Mean) "right or left and by how much" in a simple and dynamic way.

Problem with the standard deviation as an analytical tool : It is distorted
by extreme values (extremely high or extremely low) in the data series.
The key item here is "Perimeter Range" by that I mean all items can be
accounted for,for example the value(25) is know,so actual it become a base
part of the Perimeter Range,question now ?(A)will it stay"Put",and if so
"why",(B)and if not"Which way (Plus or Minus) will it move ?,(C) and by what
amount ?, all within the "Perimeter Range".

So my thinking was if all the elements was account-for,the Probability
"Prob-Function" could be use to give a value to these elements ,in this way
they could be manipulated (Randomly) in a (known-Way).

Look at the (2) known available "Answeres" in the Perimeter Range which is
(positive "3" and a Negitive "-0.745"),If it move to "3" than it would be "On
Average" if not , there are (4) items less than the(Arthimetic Mean) namely "
-0.66,-0.1,-1.27,-0.95 "by measure these (known) negitives as a group,You
will notice two(2) things either it will stay"put" or will move to one of the
listed items .

P.S. By the way, the results was to item ( -0.66)
So now "After the Fact" we know how much "Value" the move was (-0.085) !

Any thing along these lines would be helpful.

Again, Thanks in advance.

Joseph..
