NCERT Solutions for Class 10 Maths Chapter 13 - Statistics Exercise 13.3

## FAQs on NCERT Solutions for Class 10 Maths Chapter 13 - Statistics Exercise 13.3

**1. What do you Mean by Median, Mean, and Mode?**

**Mean:-** It refers to average. Mean is the average of a given set of data. We can calculate by dividing the sum of all values by several values.

Mean = (n_{1} + n_{2} +........n_{10})/10.

**Median:-** Simply, the middle term of the set is known as the set’s median. If it has an even number of terms in the set, the average of two middle terms is the median.

**Mode:-** The highest repetitive term of the set is called the mode of the set.

**2. Explain the Relationship Between Mean, Median, and Mode?**

As these three are statistical measures, all are interrelated but can't say dependent all the time. The relation can be understood easily by plotting graphs. Apart from that, after several observations, it is clear that the difference between mean and mode is equal to the thrice of the difference between mean and median. It can be represented as,

Mean – Mode = 3 (Mean – Median).

We will also get a symmetrical curve when we plot the graph while showing the relation between them. It also considers frequency distribution on the other side.

3. Can you please brief me about the Class 10 Maths Exercise 13.3?

**6. What is Statistics Class 10 Maths?**

Statistics Class 10 Maths is a branch of mathematics concerned with the collection, classification, and representation of any type of data to facilitate analysis and comprehension. There are various data representations in statistics which include bar graphs, pie charts, histograms, and frequency polygons. Class 10 Statistics comprises calculating the central tendency of grouped data with the help of three measures, i.e. mean, median and mode.

7. Which topics should I focus on most for the Class 10 Chapter 13 CBSE board exam?

CBSE Class 10 Maths Chapter 13 'Statistics' is an important chapter that can assure you with good grades. This chapter is easy to understand as well as fun to study. The main topics that are covered in this chapter are data analysis and calculation of central tendency of grouped data through the measurement of mean, median and mode. You can expect questions that ask the application of these concepts.

8. What topics are covered in class 10 maths chapter 13 exercise 13.3?

Class 10 Maths Ch 13 Ex 13.3 focuses on calculating the median of grouped data, which is a key measure of central tendency. It involves identifying the median class and understanding how to use cumulative frequency. The exercise teaches students how to apply the median formula to find the middle value in grouped data. This topic is essential for analysing statistical data. Understanding the median helps in interpreting the distribution of data sets in exercise 13.3 class 10.

9. How do I find the median of grouped data in class 10 maths ex 13.3?

To find the median of grouped data in class 10 maths ex 13.3, you need to identify the median class, which is the class interval where the cumulative frequency exceeds half of the total observations. Once the median class is determined, use the formula provided in the NCERT solutions to calculate the median. This formula involves the lower boundary of the median class, the cumulative frequency, and the class width. The NCERT solutions of class 10 maths ch 13 ex 13.3 offer detailed steps and examples to guide you through the process. Practising these steps will enhance your problem-solving skills.

10. Are there any prerequisite concepts needed for solving class 10 maths 13.3?

Yes, understanding cumulative frequency and determining class intervals are crucial for solving class 10 maths 13.3. You need to know how to calculate cumulative frequency to identify the median class. Familiarity with statistical terms and measures of central tendency is also important. These concepts are fundamental for accurately finding the median in grouped data. A solid grasp of these prerequisites will help you solve the problems effectively in class 10 maths chapter 13.3.
