"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)

Subject [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 Björn 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>
