FAQs on NCERT Solutions for Class 11 Statistics Chapter 3 Organisation of Data
1. What is the advantage of classifying things, explain?
Classification is a process of data organisation which includes separating it into different groups. In this process, students will first need to identify what makes these data differ from one another. They are then supposed to group this data based on similarity.
By segregating data, students can analyze it more effectively. This method is more prevalently used in the process of risk management in an organization. This chapter has been included in the NCERT syllabus, for students to grasp the concept of statistics with ease.
2. What are variables, and explain discrete as well as continuous variables?
Variation refers to numerical values that keep changing based on circumstances and time. It got its name, due to its unique characteristics, which is, that it keeps changing or varying. There are two kinds of variation that you will learn about in this lesson, which is discrete and continuous.
Discrete variables refer to whole numbers that tend to increase finitely. In comparison, a continuous variable is capable of taking up any numerical value and can increase infinitely. For example, the number of workers in a factory is a discrete variable, whereas the height and weight of these workers can be classified as continuous variables.
3. What are the inclusive and exclusive methods of data classification?
Students can also classify data based on exclusive and inclusive. Exclusive frequency distribution is a numerical table. Here, the upper-class limit of the first value becomes the lower class limit of the second value.
The inclusive method, on the other hand, comprises both the upper and the lower class limit within the series. This allows in proper segregation without creating any confusion for the student. The NCERT solution focuses on this section as it carries most marks weightage. This is why students will need to study this part of the chapter properly if they wish to score well.
4. What is the Organisation of Data, according to Chapter 3 of Class 11 Statistics for Economics?
The organisation of data means the systematic arrangement of the collected information. The organisation makes the data easy to understand and helps in making a further statistical investigation. First of all, data is collected from different sources. Once all data is collected, it is organized in an easy-to-understand manner. This helps in making conclusions and finding solutions. The organisation of data also helps in making comparisons between different factors. It also helps in finding important information easily and quickly.
5. Why is Data Organisation important, according to Chapter 3 of Class 11 Statistics for Economics?
Data Organisation means the arrangement of data in a systematic way. It makes the data easy to understand. Data organisation is important because it helps in the following ways:
Helps in making conclusions
Helps in easy understanding
Helps to make quick decisions
Helps in making a comparison between two similar quantities
Helps in finding important information quickly
Helps to make a record
Helps in further analysis of the given situation
6. Which series can be broken into infinite gradations, according to Chapter 3 of Class 11 Statistics for Economics?
A measurable characteristic that can take different values at different points and conditions is called a variable. The value keeps changing. Variables are of two types, Discrete and Continuous variables. A discrete variable can only take the whole numbers as a value, but a continuous variable can take any numerical value. A continuous variable can take any value and, therefore, can be broken down into infinite gradations. For example, height, weight, etc.
