Question

Find the mean and mode of the observation 8,12,5,13,12,8,9,12,8,10​

Answer 1

Answer:

Hey mate here is your answer

♦ Mean = Sum of observations ________________________ Number of observations

8+12+5+13+12+9+8+12+8+10.

= _______________________

10

= 97/10

» Mean = 9.7

♦ Mode = Most frequently occurring value

» Mode = 12 and 8

♦ Median =If the number of observations ( n ) are even then the formula is mean of n/2 and n/2th term

Arrange in ascending order = 5,8,8,8,9,10,12,12,12,13

n/2 = 10/2 = 5th term = 9

n/2 + 1 = 10/2 + 1 = 5 + 1 = 6th term = 10

Mean of both the terms = 9+10. 19

______ = ____ = 9.5

2 2

» Mode = 9.5
