Following are the marks obtained by 30 students in a examination

Taking class intervals `0-10, 10-20,….. 40-50` construct a frequency table.

The following table shows the marks scored by 140 students in an examination of a certain paper: Marks: 0-10 10-20 20-30 30-40 40-50 No. of students: 20 24 40 36 20 Calculate the average marks by using the assumed mean deviation method.

Following are the marks obtained by 25 students in Statistics . Prepare a frequency distribution by taking a class interval of 4 on exclusive basis.

The following are the marks obtained by 30 students of Class XI in Statistics. Prepare a frequency distribution by taking a class interval of 5 on exclusive basis.

Given data shows marks of 32 students in an examination. Mean of the marks will be {:("Class interval",0-10,10-20,20-30,30-40,40-50),("Frequency",12,6,8,4,2):}

The marks obtained by 32 students of a class are given below. Prepare a frequency table with class intervals 31-40, 41-50, ….. etc.

The marks obtained by 32 students of a class are given below. Prepare a frequency table with class intervals 31-40, 41-50, ….. etc.

The following table gives the marks scored by 100 students in an entrance examination. Marks:, 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-70, 70-80 No. of Students (Frequency):, 4, 10, 16, 22, 20, 18, 8, 2

The following table gives the marks scored by 100 students in an entrance examination. Marks: 0-10 10-20 20-30 30-40 40-50 50-60 60-70 70-80 No. of Students (Frequency): 4 10 16 22 20 18 8 2 Represent this data in the form of a histogram.

Given below are the marks obtained by 40 students in an examination : 40 56 24 41 51 22 59 12 26 46 51 14 23 59 58 29 41 35 36 40 42 43 36 33 38 52 23 24 13 55 18 54 20 57 30 24 43 50 26 15 Taking class intervals 10-20, 20-30,. ...., 50-60 , construct a frequency table for the above distribution.

Construct a histogram for the marks obtained by 600 students in the VII class annual examinations.
