For my class data from reading a value off the buret with water inside my class results are 11.21, 11.23, 11.23, 11.23, 11.23, 11.24, 11.24, 11.25, 11.25, 11.25, 11.25, 11.25, 11.26, 11.28, 11.28, 11.29, 11.30 from increasing order. In order to reject suspect data i need to use the Q test. I tried it but my values fall lower than the 90 % confidence level so does that mean i use all the values to calculate . And when i do the Q test do i use the repeated values also?
