Question

class:0-5 ,5-10, 10-15, 15-20, 20-25. frequency 10,15,12, 20, 9. the sum of the limit of the median class and model class is​

Answer 1

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
