| | Re: evaluation of a new machine against one in current use
Hello there! and welcome to the forum!!
I would use Excel an easy and quick way to analyze statistics.
input all 20 values from both machines into cells in the rows.
each machine should have one row.
then you can do this:
in a cell put
=(click on function average - and select the whole row of your values )
do this for each row to get average of each
then do in a new cell underneath each row:
=(click on function SD standard deviation - and select the whole row of your values )
this gives you error
then do a T-Test in a cell:
= (click on T-test function Fn and do a t-test between the two rows.)
if its less than 0.05 they are similar and not differently significant
