Q.- Briefly Explain the Basis or Methods of Classification. Mid-value or Mid-point is the central value of a class-interval. Concept of Variable A characteristic or a phenomenon which is capable of being measured and changes its value overtime is called a variable. Thus, both class limits are parts of the class interval, e.g., the class intervals of 0-5, 6-10, 11-15, and so on are inclusive. – Mid Value = (l2 +l1) ÷2. Those variables which can take all the possible values (integral as well as fractional) in a given specified range are termed as continuous variables. it is known as Geographical Classification. “Price” is a variable as prices of different commodities are different. Multi-Class Classification 4. For example, Population can be divided on the basis of marital status as married or unmarried etc. The term variable is derived from the word ‘vary’ which means to differ or change. Cumulative frequencies may be expressed on the basis of upper class limits of the class-intervals. A planned data analysis system makes fundamental data easy to find and recover. Q.1- Which of the following is the objective of classification, Q.2- Temperature, Height, Weight, Marks are an example of. Further statistical calculations are based only on the values of class mark and not on the values of teh observations in that class. A variable refers to quantity or attribute whose value varies from one investigation to another. Classification of data is the process of arranging data in groups or classes on the basis of certain properties. Hence, variable means the characteristic which varies or differs or changes from person to person, time to time, place to place etc. Note that all Classification Numbers belonging to a given Tariff Item will have the same duty rate. Q.- What is a Statistical Series? Multi-Label Classification 5.

For example, if the weight of 5 students in a class is exactly 65 kg, then the frequency of data item 65kg is 5. Answer: A mass of data in its original form is known as raw data. Individual series refers to that series in which items are listed singly, i.e. Sensitivity measures the proportion of positives that are correctly identified (i.e. (iii) Condition Series. etc.) c. To bring out points of similarity and dissimilarity among various groups. This is true for other classes as well. Classification Classification is the process of arranging things in groups or […] It is mainly a data management process. For grouping or counting the number of observations, Lower limit (. Frequency Distribution (tally bars) with class interval 11. Written methods and set of guidelines for data classification should determine what levels and measures the company will use to organise data and define the roles of employees within the business regarding input stewardship. CBSE Class 11 Statistics Chapter -1 Important Questions. The grading system is not intended for use as a measure to predict operative risk. It is obtained by successively adding the frequencies of the values of the classes. Raw data cannot be easily understood, and it is not fit for further analysis and interpretation. To consolidate the volume of data in such a way that similarities and differences can be quickly understood. Q.14- What Do You Understand by Raw Data? Whenever we employ statistical methods for the collection, classification, presentation, analysis, and interpretation of quantitative data, we term statistics as a singular noun. Q.- What is Meant by Variable? It is the process of arranging data into homogeneous (similar) groups according to their common characteristics.
