Answer 1

Answer:

Mode of a given set of numbers is a the 'most popular' number. ... The first step in finding the mode of a grouped data is to locate the class interval with the maximum frequency. The class interval corresponding to the maximum frequency is called the modal class.

Answer 2

Answer:

Mode = l+ (f1-f0)/2f1-f0-f2 × h

here F1=15

F2=11

F0=9

l =20

h=10

Now put these values in the given formula

20 + (15-11)/2×15-(11+9) ×10

20+ 4/10 ×10

20+4

24

Hence Mode is 24
