The research on the astronauts operation sEMG based on small sample data analysis

Under the extremely limited space experimental conditions, it´s still a challenge for us to make the small sample of the data ensure the validity of experimental results in a certain confidence interval. We used the theory of small sample data analysis to design and synthesize strategies in order to be adequate for reasonably good knockdown of the number of samples required for the experiment. And we applied and verified the method to determine the number of operation sEMG signal samples by using an example of space ergonomics experiment. Finally, we analyzed the applicability and reliability of this method for series of experiments and looked forward to the trend of the research directions.
