So l am testing a sensor l recently developed. I am changing parts on the sensor and testing to see if my data is reproducible with different parts. I compare the data using the KS test. However, the data always have the same distribution or trend line. To test if the two data sets are the same i.e the variations aren't due to random error. What must be my p-value ? I thought that 0.05 was too small since they had the same waveforms, so would using a p-value of let us say .5 help me determine if difference in the data sets are due to something wrong ?
