Default NORMAL DISTRIBUTION

I am not sure what the range in the graph is...
I follow this instruction:

Next, plot the normal curve. Click any cell that does not contain data and
has no adjacent cell with data. Click the Chart Wizard and select the XY
Scatter chart (sub type Smoothed line with no markers) as in the 'Enumerating
a set of points in a worksheet' section. In the 2nd step of the wizard,
select the Series tab, then the Add button. Specify the names as the x- and
y-values.
Finally, format the chart as desired.

And then, I get lost..

What do I insert in the chart wizard under ranges/

Thanks,

Hi,

Before I start getting into NamedRanges, did you try without using the named
ranges. It works wihtout as well. Simple enter the range in the graph.

thank you...however one more question...i tried graphing the normaldist

using
the name, define routines..i.e.creating a graph using formulas..

when i get to the series tab, and i insert, for x, =NormCurveXVals, i get

a
reference error..

in other words, i cannot, YET, make it work..

i believe my formulas are all entered correctly in the name, define

section,
but the chart wizard will Not accept my X value.

Can you be of more assistance?

thanks

Hi,

First of all I want to clarify that this is not my site. It belongs to
Tushar Mehta (http://www.tushar-mehta.com).

I haven't checked the addin, but follow the method on his site by

entering
the range -4 to 4 in column A, you could skip column B for mean=0 and
stdev=1. In C, enter the formula for Normdist as mentioned on the site.

Now the extra part. In column D, enter
=IF(A2<=$K$1,NORMDIST(B2,0,1,FALSE),0)
or
=IF(A2<=$K$1,NORMDIST(B2,$F$1,$H$1,$D$1),0)
where K1 has a z value, the left of which you want the portion

blackened.

Now plot both the columns (C and D) in an area chart with no fill for

the C
plot, and a black fill for the D part.

E.g. The cell K1 will have a z value like say -1, and in the area chart

will
have the area left of -1 blackened.

Using TRUE in column C formula will give you the cummulative

distribution.

I do not know who you are, but I am very impressed. I am a
Calculus/Statistics instructor; I only wish to apply my extensive
mathematical skills with EXCEL; your site is certainly great...

Next, can you possibly help me with the (integral..under the

curve)...I
believe we insert true...,etc?

I know EXCEL has functions for both the NORMAL DISTRIBUTION and the
cumulative value thereof...

but is it possible to graph this data..

(I imagine if I sort the data and then calculate the cum.

distributions
into
a column...then chart it, it should work; BUT IS THERE ANOTHER WAY?)

thank you,
