1) The median for the month of March was 2,240 ft³/sec.  What does that really mean?
    a) On March 15th, the discharge of the Red River was 2,240 ft³/sec.
    b) On March 16th, the discharge of the Red River was 2,240 ft³/sec.
    c) If you add up all of the values between March 1st and March 31st, and divide by 31, the answer is 2,240 ft³/sec.
    d) Not including the median itself (2,240 ft³/sec), half of the values for the month of March are below 2,240 ft³/sec; half of the values for the month of March are above 2,240 ft³/sec .

    b) Which months had the largest and smallest range.
    c) The average pattern of the Red River's flow during the three months.
    d) Which months had the largest and smallest mean values.

4) In general, if the "box" part of one box plot is longer than another,
    a) More numerical values were used to create that box plot
    b) Less numerical values were used to create that box plot
    c) The difference between the first and third quartiles is larger on that box plot
    d) The difference between the first and third quartiles is smaller on that box plot
