What is the difference between class Mark and class interval?
Class interval = Upper-class limit- lower-class limit. Class Mark is defined as the mid-value (or middle value) of each class interval. The upper limit of the class is the maximum value or the value above which there exists no item in that class.
What is the class mark of 25 - 35?
Solution: By using the class mark formula, we have, Class mark = (upper limit + lower limit)/2. The given class is 25 - 35, where 25 is the lower limit and 35 is the upper limit. Therefore, the class mark of 25 - 35 is 30. Example 2: If the class mark is given as 55 and the upper limit is 65, find the value of the lower limit of the class interval?

How do you find the class mark?
The average of the class limits is (180 + 199) / 2 = 189.5. This is your midpoint. You might see the class mark defined as the average of the class boundaries as well. You'll get the same result.

What is the class mark of modal class?
The class interval with the highest frequency is considered the modal class. Looking at the frequencies, the highest is 43. Therefore, the modal class is 60-70.
What is called class interval?
Class interval refers to the numerical width of any class in a particular distribution. Mathematically it is defined as the difference between the upper-class limit and the lower class limit. Class interval = upper-class limit - lower class limit.
What is the class width?
Class width is the difference between the Upper class limit and the Lower class limit of a class interval. Class Width = Upper Class Limit − Lower Class Limit. For example: For a class interval, 163−175, Class Width =175−163=12.
What are classes in statistics?
In statistics, a class is a grouping of values by which data is binned for computation of a frequency distribution (Kenney and Keeping 1962, p. 14).

What is the purpose of the Nice classification?from wipo.int
The International (Nice) Classification of Goods and Services for the Purposes of the Registration of Markswas established by an Agreement concluded at the Nice Diplomatic Conference, on June 15, 1957, and was revised at Stockholm, in 1967, and at Geneva, in 1977. The countries party to the Nice Agreement constitute a Special Union within the framework of the Paris Union for the Protection of Industrial Property. They have adopted and apply the Nice Classification for the purposes of the registration of marks. Each of the countries party to the Nice Agreement is obliged to apply the Nice Classification in connection with the registration of marks, either as the principal classification or as a subsidiary classification, and has to include in the official documents and publications relating to its registrations of marks the numbers of the classes of the Classification to which the goods or services for which the marks are registered belong. Use of the Nice Classification is mandatory not only for the national registration of marks in countries party to the Nice Agreement, but also for the international registration of marks effected by the International Bureau of WIPO, under the Madrid Agreement Concerning the International Registration of Marksand under the Protocol Relating to the Madrid Agreement Concerning the International Registration of Marks, and for the registration of marks by the African Intellectual Property Organization (OAPI), by the Benelux Trademark Office and by the Office for Harmonization in the Internal Market (Trade Marks and Designs) (OHIM). The Nice Classification is also applied in a number of countries not party to the Nice Agreement (see list on page (viii)).
