   Pass 3 is empty, so mean() fails first. Pass 2 has one reading — mean and median work, but standard deviation needs at least two values. The message tells you which function failed first, and printing str(error) gives you exactly the expected text.

      Makes sense, the first failing call decides the message.

         Didn't know there were two. Good to know.

   stdev is sample standard deviation; pstdev is population. For sensor readings, stdev is the usual choice.
