The class marks of a distributions are:
37,42,47,52,57,62,67,72,77,82,87,92
find the class size, the limits and true class limits.

Explain the meaning of the following terms: true class limits

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

The mid value of a class interval is 42 and the class size is 10. find the lower and upper limits.

The weights (in kg.) of 15 students of a class are: 38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38, 43, 38, 47 Find the mode and median of this data.

The weights (in kg.) of 15 students of a class are: 38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38, 43, 38, 47 Is there more than one mode?

The marks obtained by 35 students of class IX of a school are given as below: 17,9,11,9,15,11,4,22,1,17,24,3,11,20,12,9,7,0,5,3,5,13,21,13,15,20,24,1,7,21,22,10,13,18,24. present the data in the form of a frequency distributions, using same class size, starting with class 0-5

The following are the marks of 60 students in Mathematics 16,13,5,80,86,7,51,24,56,70,19,16,36,34,42,34,35,73,55,75,52,72,97,74,45,62, 68,86,35,81,75,55,26,95,31,7,78, 92,62,52,56,15,63,25,54,44,47,27,17,4,30 Construct a grouped distribution table with width 10 each of the class starting from 0-9.
