Question

Find the mode
C.I:0-100 10-20 20-30 30-40 40-50 50-60 60-70 70-80
Fre: 7 9 10 16 7 8 15 8

Answer 1

The highest frequency of the given data is 16.

therefore, Modal class =30-40

so, fo = 10, f1 = 16 , f2 = 7 , l= 30 and h=10

NOW, mode = l+( f1-fo/2f1-fo-f2) * h

= 30+(16-10/2*16-10-7) * 10
= 30+(6/15)*10
=30+(2/5)*10
=30+2*2
=30+4
=34.

HENCE, mode of the given data is 34.

HOPE IT HELPS YOU .

Answer 2

✌️✌️ hey mate,


The highest frequency of the given data is 16.

therefore,

Modal class =30-40

so,

fo = 10,

f1 = 16 ,

f2 = 7 ,

l= 30

h=10

NOW,

mode = l+( f1-fo/2f1-fo-f2) × h

= 30+(16-10/2*16-10-7) × 10
= 30+(6/15)× 10
=30+(2/5) ×10
=30+2 ×2
=30+4
=34.

HENCE,

Mode of the given data is 34.


thanks....
nice to help you ✌️✌️
