Question

18. Find the mean, mode and median of the following data,
a. 12, 13, 14, 14, 11, 16, 14, 18
b. 63, 68, 69, 70, 74, 64, 68
c. 10, 20, 20, 30, 40, 50, 20
d. 20, 15, 10, 5, 16, 20, 11, 20, 18​

Answer 1

Step-by-step explanation:

a) mode=14

median=n+1/2=8+1/2=4.5th term

4.5th term=4th term+5th term/2

=14+14/2=28/2=14

mean=12+13+14+14+14+11+16+18/8

=112/8=14

b) mode=68

median=n+1/2

7+1/2=8/2=4th term=68

mean=63+68+69+70+74+64+68/7

476/7=68
