Suppose two students are interested in gathering data on the height of
students at NVC (let’s pretend this is pre-pandemic times, and most
classes are on campus face-to-face).
Student A chooses random times of day and random locations on campus to
survey those passing by.
Student B stands outside the gym as basketball practice is beginning and
surveys those entering.
Which student will most likely have data with the smaller standard
deviation? Why?
