1.	Find the median of 12,13,14,15,16,17,18,19,20 fi= 7,10,15,18,20,10,9,8,3
Answer» ANSWER: Median = 15 Step-by-step explanation: write c.f (cumulative FREQUENCY) 7 , 17 ,32 ,50 ,70,80 ,89,98,101 Median = total frequency + 1/ 2 = 101 + 1 /2 = 51 check around VALUE of 50 in c.f so value is 50 corresponding x value is 15

Find the median of 12,13,14,15,16,17,18,19,20 fi= 7,10,15,18,20,10,9,8,3

Answer»

ANSWER:

Median = 15

Step-by-step explanation:

write c.f (cumulative FREQUENCY)

7 , 17 ,32 ,50 ,70,80 ,89,98,101

Median = total frequency + 1/ 2

= 101 + 1 /2

= 51

check around VALUE of 50 in c.f

so value is 50 corresponding x value is 15
