2.1 hours
MAD
0.5 hours
0.2 hours
0.6 hours
Based on the data, which trial was most likely biased, and why?
Trial 3 because the mean is lowest.
Trial 3 because the MAD is highest.
Trial 2 because the MAD is at least 0.3
below the MAD of each other trial, and
this is larger than the MAD of Trial 2.

Trial 2 because the mean is at least 0.7 away from the mean of each other
trial, and this is larger than the MAD for each other trial.
