Outcomes of democracy class 10

In a frequency distribution, the mid values of a class is 10 and width of the class is 6 . The lower limit of the class is

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 .

Find the actual lower class limits , upper class limits and mid values of the classes : 10 -19 , 20 - 29 , 30 - 39 , and 40 - 49

The starting value of the model class of a distribution is 20. The frequency of the model class is 18. The frequencies of the classes preceeding and succeeding are 8,10 and the width of the model class is 5, then mode is

The outcome of each of 30 items was observed , 10 items gave an outcome (1)/(2)-d each, 10 items gave outcome (1)/(2) each and the remaining 10 items gave outcome (1)/(2) +d each. If the variance of this outcome data is (4)/(3) , then |d| equals

The width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10. The upper class limit of the highest class is

Find the class marks of classes 10-25 and 35-55.

Find the class marks of classes 10-25 and 35-55.
