Question

Find the mean and medium of the following data :- 12,36,35,24,15,8,16,9,26,25,23,17​

Answer 1

Answer:

Mean = 19.25

Step-by-step explanation:

mean = sum of observations / total no. of observation

mean = 231/12

mean = 19.25

median = 8,9,12,15,16,17,23,24,25,26,35,36

median = n/2term + (n/2 + 1) term  /  2

n=12

median = 12/2term + (12/2 + 1)term  /  2

median = 6term + 7term  /  2

6 term = 17

7 term = 23

median = 17 + 23 / 2

median = 40/2

median = 20 (Ans.)

Answer 2

Step-by-step explanation:

mean-231/12

median=8,9,12,15,16,17,23,24,25,26,35,36

median -17 +23/2 40/2 =20

20 is the answer of this question
