Question

Find the mode of the ballowing frequency
Distribution:
C.I 0-5/5-10/10-15/15-20/20-25/25-30
Frequency
2/7/18/10/8/5​

Answer 1

Answer:

65

Step-by-step explanation:

f1=18

f0=7

f2=10

L=10

h=5

l+f1–f0/f1–f0–f2×h

10+18–7/18–7–10×5

10+11/1×5

10+55

=65

Answer 2

Answer:

mode=12.89

Step-by-step explanation:

modal class = class interval with highest frequency

L= lower boundary of the modal class interval

f0=frequency preceding the modal class

f1=frequency of modal class

f2=frequency succeeding the modal class

h=height of the class interval
