Question

Calculate the mode of th following
CI 25-30 30-35 35-40 40-45 45-50 50-55
Frequency 25 34 50 42 38 14​

Answer 1

Answer:

Here modal class is 35-40

Therefore l =35, F1=50, f0=34,F2= 42,h=5

By formula,

Mode = l+ (f1-f0)/2f1-f0-f2)×5

=35+(50-34)/(100-76)×5

= 35+ (16×5)/24

=35+ 80/24

= 35+ 3.33

= 38.33

Therefore the mode of the above question is 38.33
