Calculate average number of marks by student in a class. Note: It is inclusive class case with lower limit of the first class is zero.

In a continuous frequency distribution ,class mark of a class 15 and lower limit is 13, then the upper limit is:

The middle point of a class is 24 and the length of each class is 10 , then calculate the upper and lower limit of the class of the class interval.

Determine the median weekly income using upper limit method.

Given data: The difference between the upper limit of the median class and the lower limit of the modal class is -

The class marks of a class is 25 , and if the upper limit of that class is 40 , then its lower limit is "_______"

The data regarding marks obtained by 48 students of a class in a class test is given below. Calculate the modal marks of students.

The middle point of a class is 10 and the length of each class is 12 , then calculate the lower limit of the class of the class interval.
