Dear all,
I am trying to figure out how the origin calculates the Standard Erro on "statistcs of colum". There is any formula to know about any unit standard erro could have ?
Thanks a lot. |

Hi,
Here is a link that lists the equations corresponding with the the statistical quantities that can be determined with the Statistics on Columns dialog box, including standard deviation. Hopefully this is what you are looking for.

Oh thanks a lot. I have already calculated the standard erro using this process in Origin. But I would like to know how the program make this calculus. What formula it uses ? To know about any unit a must use when presenting the standard erro. |

Hi,
1) You can create a new column within the worksheet and calculate the standard deviation by inputting a function for the set value, input StdDev(x)
http://www.originlab.com/index.aspx?go=Products/Origin/DataManagement/WorkbooksAndWorksheets&ss=chm&pid=1166
or
2) You can use the Statistics on Column dialog box
http://www.originlab.com/doc/Tutorials/DescStats#Calculating_Descriptive_Statistics_on_Grouped_Data
or
3) Another option that might be helpful is that you can use the statistics gadget, which can calculate the standard error of your plotted graph:
