Hi
I would like to perform a blind test to rank the 'sound quality' of five different vacuum cleaners. The study shall be performed by running each vacuum cleaner and then asking a voting panel to rank the perceived sound quality from 1 to 10 (1 being worst and 10 being best). Also i would like to have 3 repeats (with randomization) of the rankings so i have more confidence in the results. Can anyone tell me how should i analyse the results? Also if there are any suggestions on how to conduct this study?
Thanks
