    Answer:

    1st  Qtrl:  11

    Median:  20.5

    3rd Qtrl:  25.5

    Range:  22

    Step-by-step explanation:

    Median = average of 2 middle values (18 + 23) / 2

    1st Qtrl = average of 10 and 12 (the lower half of data)

    3rd Qtrl = average of 25 and 26 (the upper half of data)

    Range = largest value – smallest value;  30 – 8 = 22
