Problem
The standard deviation of the daily maximum temperature in a city over one month is found to be almost zero. What does this imply about the temperature readings?
(a) The temperatures were nearly the same on all days.
(b) The temperatures varied widely from day to day.
(c) The average temperature of the month was approximately zero.
(d) Very few temperature readings were taken during the month, so variability appears small.
