Question

find the mode of the following table ​

Answer 1

Answer:

Mode

class interval frequency

0-10 4

10-20 5

20-30 16

30-40 12

40-50 3

50-60 2

Maximum frequency =16

Modal class=20-30

Lower limit(L) =20

Class size(h)=10

Frequency of modal class(f1)=16

Frequency preceeding the class(f0) = 5

Frequency succeeding the class(f2)= 12

Mode = L+[f1-f0/2f1-f0-f2]×h

=20+[16-5/2×16-5-12]=20+11/15

=20+0.73

=20.73

plz mark it as the brainliest answer

Mode =20.73
