calculating line by line


I'm completely new to KNIME and it seems to me that KNIME calculate only colume wise. I want to simple calculation of average, Standard Deviation and coefficient of variaten between different values in a single line. How do I do that in KNIME?

For better understandig I have uploaded an Excel file with a table. The gray cells are the columns I want to create in KNIME.


Thank you

That can be done with the “Math Formula” node.

With one node I only can insert one column. For three calculations I need three nodes. Is that right?
