NCERT Solutions for exercise 14.1 Class 9 Maths chapter 14 statistics is the important chapter of NCERT solutions for Class 9 Mathematics. We have provided solutions to it below, which will be quite useful when performing assignments. As from smaller Classes, we know that statistics is an area of mathematics concerned with gathering, analysing, interpreting, and presenting large amounts of numerical data.

Talking about exercise 14.1 Class 9 Maths is an Introductory exercise of the chapter that includes all Theory problems. Here In this NCERT exercise 14.1, we will be studying how statistics get implemented in day-to-day life. In chapter 14 of Class 9 NCERT Mathematics book, the concept of Primary and Secondary data is discussed using examples mentioned in the chapter.

The NCERT syllabus Class 9 Maths chapter 14 exercise 14.1 lists some basic level points to understand the concepts of statistics fully and can understand the value of problems for upcoming exercises. The Class 9 Maths chapter 14 exercise 14.1 covers Initial topics with examples that are like the base for concept building and understanding. Many real-life scenarios are discussed in NCERT solutions for Class 9 Maths chapter 14 exercise 14.1. Along with Class 9 Maths Chapter 1 exercise 14.1 the following exercises are also present.

1. Define Statistics?

Ans: The study of data collection, analysis, interpretation, presentation, and organisation is known as statistics. To put it another way, it is a mathematical field that collects, summarises, and analyses data.

2. Why statistics are important?

Ans:. Statistics are very important in order to get a brief implication of topic along with the data given hence its good for students to have deep understanding.

3. Does statistics means collection of data?

Ans: Collection of data is a part in the process of collection of data, in this we collect data and work  that data.

4. Is Statistics property of data or study of data?

Ans:  statistics is the property of studying data from the given extent.

5. How many types Questions are there in chapter 14 exercise 14.1?

Ans: There are a total of 2 question in the exercise 14.1.

Ans: there are total of 4 exercises in chapter 14 that is 14.1, 14.2, 14.3, 14.4

7. What is parameter term in statistics?

Ans: Any value or group of data we pass in order to get result of certain value is called parameter

8. What passing parameter is very important in statistics

Ans: We know very well that we will be getting accurate data when we pass the value by which we needed hence in order to work on accuracy we will be passing parameter in statistics
