1.) What is means by Chronological Classification?
Ans – The raw data is classified in various ways depending on the purpose. They can be grouped according to time. Such a classification is known as a Chronological Classification.
2.) What is means by Qualitative Classification along with example?
Ans – Sometimes you come across characteristics that cannot be expressed quantitatively. Such characteristics are called Qualities or Attributes. For example, nationality, literacy, religion, gender, marital status, etc. They cannot be measured.Yet these attributes can be classified on the basis of either the presence or the absence of a qualitative characteristic. Such a classification of data on attributes is called a Qualitative Classification.
3.) What is means by frequency distribution and class frequency?
Ans – A frequency distribution is a comprehensive way to classify raw dataof a quantitative variable. It shows how different values of a variable are distributed in different classes along with their corresponding class frequencies. In this case we haveten classes of marks: 0–10, 10–20,20-30 … ,60-50 The term Class Frequency means the number of values in a particular class.
4.) What is means by class limited and class width?
Ans – Each class in a frequency distribution table is bounded by Class Limits. Class limits are the two ends of a class. The lowest value is called the Lower Class Limit and the highest value the Upper Class Limit. For example, the class limits for the class: 50–70 are 50 and 70. Its lower classlimit is 50 and its upper class limit is 70. Class Width is the difference between the upper class limitand the lower class limit. For the class 50–70, the class interval is 20.
5.) How should we get the frequencyfor each class?
Ans – In simple terms, frequency of anobservation means how many times that observation occurs in the raw data.
