Origin Ver. 9.1 (91E) and Service Release a (Select Help-->About Origin):
Operating System: Windows 7 Pro
Hi,
I'm new user of Origin and I found some problem with average value calculation. I'd like to get:
1. Average value from 2 separate columns. There are one parameter measured twice, and I'd like to calculate overall average value.
2. Average values from 2 columns, but calculated row by row. I have two sets of data and I'd like to get third one which will be the average value. (something like average value of two vectors).
And I have one more question, where can I find detail description of "Set value" tool and built-in functions eg. "mean(vd)", how it works and what mean v or d, how should I define range etc.
Kind regards,
Dominik |

Hi dominik,
> 1. Average value from 2 separate columns... overall average value.
You can highlight these two columns, choose "Statistics> Descriptive Stats> Stats on Columns" menu. In this tool, you can control with option for how the statistics are calculated - {Independent Columns / Combined as Single dataset} at "Input Data" option node.
> 2. Average values from 2 columns, but calculated row by row.
Assuming you have only two columns as the source data, you can highlight these two columns, choose "Statistics> Descriptive Stats> Stats on Rows" menu.
For the general explanations about Set Column Values tool, you can find it at:
http://www.originlab.com/doc/Origin-Help/Wks-Set-Column-Values
For the description about a specific function, you can find at:
http://www.originlab.com/doc/LabTalk/ref/General-Stat
The same help information to the above web document can be also found in Origin help document.
Hope this works.

Hi,
Thank you for explanation. The second case is solved but I have some problem with the first one. Which option should I choose to present the calculated mean value in the column next to the source one? Am I right that the report is the only way to present the mean value?
Kind regards,
Dominik |
