Following is the distribution of marks of 50 students: What is the lower limit of second class?

From the given table, The Frequency Distribution Table in statistics provides the information on the number of occurrences (frequency) of different values distributed within a given time or over a given interval in a list, table or graphical representation. A frequency distribution is a table that shows classes or intervals of data with a count of the number in each class. The two boundaries of class are known as the lower limits and the upper limit of the class. The second class in the table is 10 ‐ 20 . Therefore, the lower limit in the of the second class is 10 .

Following is the distribution of marks of 50 students: What is the upper limit of 4 th class?

From the given table, The Frequency Distribution Table in statistics provides the information on the number of occurrences (frequency) of different values distributed within a given time or over a given interval in a list, table or graphical representation. A frequency distribution is a table that shows classes or intervals of data with a count of the number in each class. The two boundaries of class are known as the lower limits and the upper limit of the class. The fourth class in the table is 30 ‐ 40 . Therefore, the lower limit in the of the second class is 40 .

Following is the distribution of marks of 50 students: What is the class mark of 8 th class?

From the given table, The Frequency Distribution Table in statistics provides the information on the number of occurrences (frequency) of different values distributed within a given time or over a given interval in a list, table or graphical representation. A frequency distribution is a table that shows classes or intervals of data with a count of the number in each class. The two boundaries of class are known as the lower limits and the upper limit of the class. The eighth class in the table is 70 ‐ 80 . Class mark = 70 + 80 2 = 150 2 = 75 Therefore, the class mark of eighth class is 75 .

Following is the distribution of marks of 50 students: What is the class mark of fifth class?

From the given table, The Frequency Distribution Table in statistics provides the information on the number of occurrences (frequency) of different values distributed within a given time or over a given interval in a list, table or graphical representation. A frequency distribution is a table that shows classes or intervals of data with a count of the number in each class. The two boundaries of class are known as the lower limits and the upper limit of the class. The fifth class in the table is 40 ‐ 50 . Class mark = 40 + 50 2 = 90 2 = 45 Therefore, the class mark of fifth class is 45 .

Following is the distribution of marks of 50 students: What is the class size or the class width of the above distribution?

From the given table, The Frequency Distribution Table in statistics provides the information on the number of occurrences (frequency) of different values distributed within a given time or over a given interval in a list, table or graphical representation. A frequency distribution is a table that shows classes or intervals of data with a count of the number in each class. The two boundaries of class are known as the lower limits and the upper limit of the class. Class size refers to the difference between the upper and lower boundaries of a class in a frequency distribution. Class size = 20 - 10 = 10 Therefore, the class size of the distribution is 10 .
