Find the mean, median and mode for the following list of values? (a) 15, 19, 15, 14, 15, 16, 14, 21, 15 (b) 10, 11, 11, 13, 10, 10, 10, 16, 15, 14 (c) 2, 3, 5, 7, 8, 9 (d) 5, 6, 7, 7, 7, 9, 9, 9, 12, 10
Answers
Answer:
at first we arrange in assending order
a) mean = 14+14+15+15+15+15+16+19+21/9 =16 then mean = 16
median = 15 ( 9+1)/2th term
mode = 15 ( 4) times
Step-by-step explanation:
b) mode = 10
median = 11
mean = 12
