I was given this question by my friend who said he got it from his teacher (which meant he couldn't clarify the terms in this question).
The question is: What is a better measure of central tendency? The mean or the median?
I'm not sure what 'central tendency' means but I was thinking it means "the middle". If so, I thought the median by definition will be the best, since its definition is that it's the middle value.
I can't think of any case when the mean is better. In a sample with outliers, the median beats the mean.
In censored observations, median also beats the mean.
When does the mean beat the median?
