have small data and want to run basic statistical analysis.
I am comparing trainees performance using standard machine and new machine.
have 9 subjects, each will perform in 2 scenarios using one machine in each. We will record the performance as time stamps. Then we wanna see if there is a difference in the individual performance (hypothesis is the new machine will make them perform faster) or the group performance.
Sub analysis: the 9 individuals are actually 2 groups from different backgrounds (6 and 3), we also wanna see if their background played a role in the difference.
