Question

Class 0-5 5-10 10-15 15-20 20-25 Frequency 10 15 12 20 9 The sum of the lower limits of the median class and modal class is A) 15 B) 25 C) 30 D) 35​

Answer 1

Answer:

Hence, lower limit of the median class is 10. The highest frequency is 20, which lies in between the interval 15 – 20. Hence, lower limit of modal class is 15. Therefore, required sum is 10 + 15 = 25.
