Write the median class of the following distribution: Classes: 0-10 10-20 20-30 30-40 40-50 50-60 60-70 Frequency: 4 4 8 10 12 8 4

While calculating mode the following observation are found. Lower limit of modal class =40, frequency of modal class =20, frequency of previous class =12 , frequency of preceding class =11 and width of the class =10, find mode .

In a frequency distribution, the mid-value of a class is 15 and the class intervals is 4. The lower limit of the class is 10 (b) 12 (c) 13 (d) 14
