How do I create a bell curve?
 

I'd like to create a bell curve with certain values to be distributed over a
certain period of time. How do I do this?

Any help would be much appreciated.

You may want the function NORMDIST. Look it up in Excel help.

Was it not suggested a week ago that you formulate the same question
more precisely, tho' David Bidduph's suggestion on NORMDIST should be
checked

How do I create a bell curve?
 

Thank you guys.

To be more precise:
Say I have a budget of 4,200,000 to distribute over one financial year. I'd
like to create a bell curve, which would split this value relatively evenly
over the 12 months (using whichever formula the bell curve needs so that the
distribution is slightly skewed towrds the positive x values). The purpose is
to have a nice graphical representation of the approximate distribution - the
values do not need to be exact).

To be more precise:
Say I had a budget of 4,200,000 to be distributed over the 12 months of a
financial year. I'd like to create a bell curve as a graphical representation
of the financial distribution over this time, using whatever formula needed
to create a normal looking bell curve (but slightly skewed towards the
positive values on the x axis). Thus, the values don't have to be exact, so
long as the overall budget amount is correct, and the bell curve appears as
described above.

I'm not sure how to do create this bell curve.

Any ideas?

Thanks!

If you don't want an exact normal curve, why don't you just hand sketch
a curve, read off the numbers and draw a smooth curve thro' them.

How do I create a bell curve?
 

Thanks to all of you.
I am trying to use the NORMDIST function to create my bell curve, and am
putting the following values into a table:
84000
126000
210000
252000
294000
336000
378000
420000
462000
504000
546000
588000
However, the function is returning '0' for all of them. Eg. for the first
value I entered: =NORMDIST(B79, 350000, 1.5, TRUE), then: =NORMDIST(B80,
350000, 1.5, TRUE) for the second value etc. What am I doing wrong?

For a distribution with a mean of 350000 and a standard deviation of 1.5,
your value of 84000 is 177333 standard deviations below the mean, so what
would you expect the cumulative probability to be? Zero sounds a good
approximation to me.
When you get down your table to 378000, you switch from a large number of
standard deviations below the mean to 18667 standard deviations above the
mean, and then the cumulative probability steps up to 1. Isn't that what
you'd expect?

Have you looked again at Excel help for the NORMDIST function to remind
yourself what it does and what the syntax is? What were you expecting the
function to tell you?
