"Standard
error (standard deviation of the mean) of a data series assuming an equal
distribution"
I believe "assuming a normal distribution"
is the typical wording. In that case the standard error = StandardDeviation/Sqrt(N)

[office] Proposal: Error bar category
standard-error
Hi,
while implementing the ODF 1.2 enhancements for the error category of
business charts, OOo Chart's developer Bj顤n Milcke noticed that one
value in the "choice" for the chart:error-category is missing:
the
standard-error. It's a reasonable value, that some applications do
support already.
He therefore proposed the following small enhancement:
In chapter "16.33.2 Error Category" add the following value to
the
choices for the error-category:
[..]
* Standard error (standard deviation of the mean) of a data series
assuming an equal distribution
[..]
<define name="style-chart-properties-attlist" combine="interleave">
<optional>
<attribute name="chart:error-category" a:defaultValue="none">
<choice>
<value>none</value>
<value>variance</value>
<value>standard-deviation</value>
<value>percentage</value>
<value>error-margin</value>
<value>constant</value>
* new * <value>standard-error</value>
<value>cell-range</value>
</choice>
</attribute>
</optional>
</define>
Best regards
Michael
