Hi @all,

i am new at OriginLab.
What is the best way to create an evaluation with 3 variables? I have a value X that depends on the temperature, the pressure and the magnetic field.

Thank you
Matpow

If you are looking for linear correlation, you can use Multiple Linear Regression tool (menu Analysis->Fitting->Multiple Linear regression..)

Hi James,

thank you for your answer.
I have 3 results / samples for each setting. What is the easiest way to get the mean value and the standard deviation in my example (see appendix). My problem is that the values ​​appear one below the other and are linked to other sizes.

If you want statistics on grouped data, you can use the statics on columns tool:
