Question

Find the mean,median and mode of each of the following sets of data (1) 7,19,19,7,25,7
(2) 18,21,18,3,12,15,18,42,6,3,24,12
(3) 7,3,4,5,2,3,4,5,7,7,5,7,3,6,7,7

Answer 1

Answer:

(1) Mean: (7+19+19+7+25+7)/6= 14

median: 7+19/2= 13

mode: 7

(2) mean: (18+21+18+3+12+15+18+42+6+3+24+12)/12

median: 15+18/2=16.5

mode: 18

(3) mean: (7+3+4+5+2+3+4+5+7+7+5+7+3+6+7+7)/16= 5.125

median: 5+5/2=5

mode: 7

Explanation:

mean= sum of observations/ n. of observations

median = mid value

mode = most repeated value
