Explanation / Answer
Score 1:
mean = 56/10 = 5.6
median = 5.5
REASON: Arraging data in ascending order: 3,4,5,5,5,6,6,7,7,8
Median = (n+1)/2 th item = (10+1)/2 th item = averge of 5th & 6th item = (5+6)/2 = 5.5
mode = 5
REASON: 5 is repeated max. number of times
Score 2:
mean = 276/10 = 27.6
median = 25
REASON: Arranging data in ascending order: 14,17,23,24,25,25,26,34,34,54
median = (10 +1)/2 item = mean of 5th & 6th item = 25
mode = 34 & 25
REASON: Both are repeated 2 times
Score 3:
mean = 1443/10 = 144.3
median = 149.5
REASON: Arranging in ascending order: 113,123,132,145,145,154,154,154,156,167
median = (10+1)/2th item = mean of 5Th & 6th item = (145+154)/2 = 149.5
mode = 154
REASON: 154 is repeated 3 times
