Question

Find the mode of the following table

Class Interval 0-10 10-20. 20-30 30-40 40-50 50-60

Frequency 5 7 15 8 3 2​

Answer 1

f1=15, f0=7, f2=8, l=20, h=10

formula to find mode= (l+f1-f0/2f1-f0-f2 ×h)

acc to formula: 20+(15-7/ 2×15-7-8) ×10

20+(8/30-15) ×10

20+8/15 ×10

20+16/3

20+5.3

mode=25.3
