Homework Answers
a.
MEAN = TOTAL / NO. OF OBSERVATIONS
= 4+10+6+20 / 4
= 40/4 = 10
MEDIAN = (n/2)th observation + (n/2+1) observation
2
rearranging the order = 4 , 6 , 10 , 20
n = 4
n/2 = 4/2 = 2
2nd observation = 6
n/2 +1 = 2+1 = 3
3rd observation = 10
MEDIAN = 6 + 10 / 2
= 16/2
= 8
MODE = THE NUMBER THAT REPEATS MORE. HERE NO NUMBER IS REPEATED SO THERE IS NO MODE VALUE.
