Origin Ver. and Service Release (Select Help-->About Origin): 8.5.1
Operating System: WinXP

Hi,

what is the easiest way to get the average value of a part of a column?
Do I need to get into Labtalk for this? If yes, is there a good place to start? The sources that I found are not doing a very good job in documenting - or I might be spoiled by the Mathematica documentation.
In excel it is a trivial problem: I just use Average(A1:A5) to get the average value of column A, rows 1 to 5. Is there something similar in Origin?
Note: I know there is "statistics on columns", but I need to calculate something with the average. So I need to access that number. And the approach that uses this looks like a workaround. Ideally I'm looking for something that I can put into "set column values".

Any help would be appreciated.

For who visit this thread:

Origin 2015 version has introduced a handy tool - you can show the descriptive statistics of the
selected range in the status bar, and copy-and-paste to anywhere like in another worksheet
(by right-clicking the status bar):

Thank you! That should do the trick!

Hi mooto,

You can define a range, and apply "sum" function which produces a sum object which contains
properties such as 
sum.N, -.total, -.mean, -sd, -.min, and -.max
After running this function, you can keep the value by assigning to a variable(e.g., mymean=sum.mean),
or store in a cell in a worksheet cell (e.g., col(B)[1]=sum.mean).



Is it workable for you?
