Question

find the mode of the following data class:1-3,3-5,5-7,7-9,9-11 and frequency is 6,9,15,9,1​

Answer 1

Answer:

9 is the mode of this question.

Answer 2

Answer:

the answer is 6

Step-by-step explanation:

so the highest frequency is 15 therefore modal class is 5-7

lower limit = 5

f1= 15

f0 = 9

f2= 9

h= 2

mode= l+ (f1-f0/2f1-f0-f2) *h

= 5+ (15-9/30-9-9)*2

= 5+ (6/12)*2

= 5+1/2*2

= 5+1( as 1/2 and 2 get cut)

= 6
