Measures of Central Tendency

1. Introduction

NCERT Solutions Class 11 Statistics Chapter 5 wants to introduce the measures available for the central tendency in Statistics as the students have learned the collection of data and the representation of data. The next one is analyzing and interpreting the data. To analyze the data, we have three different measures of central tendencies, such as arithmetic means, median, and mode.

2. Arithmetic Mean

The arithmetic mean is a broadly used measure to calculate the average of the given data. NCERT Solutions for Class 11 Statistics Chapter 5 also explains two different variations called, mean for grouped data and mean for ungrouped data. For any kind of method, the arithmetic mean is the sum of all observations divided by the number of observations. A formula can represent it, and the students can proceed to calculate the mean for given data.

Statistics Class 11 NCERT Solutions' Measures of Central Tendency specify that the calculation of mean for ungrouped data and grouped data has three different kinds of methods. They are a direct method, assumed method, step division method. Each method may differ from grouped data and ungrouped data.

The NCERT Solutions Class 11 Statistics Chapter 5 clearly explains available on the official website of Vedantu with an illustration. Again the grouped data has two kinds of series namely-discrete series and continuous series.

3. Median

In this section, the students are advised to learn another measure of central tendency, median. The NCERT Class 11 Statistics Chapter 5 Measures of Central Tendency explains that the median is a simple concept. It can be calculated as taking the middle value, which separates both sides of the values will be equal. But it is possible only if the size of the series is an odd number. If the students are asked to find out the median for a set of even number values, then we need to take the two middle terms and find out the average for those two terms.

Quartiles are another topic explained to the students. If the whole size is divided into four equal parts, then it is called quartile. It can be calculated separately for both series by themselves.

Percentiles are a topic for which the whole size is divided into 99 Parts which reaches the cent.

4. Mode

Class 11 of Statistics Chapter 5 is explained by our NCERT solutions that specifies the students to understand each measure of central tendency. Because if the students can understand the meaning and formula, it is difficult to forget. Even though the mode is the last measure of central tendency, it has a lot of significance. The mode is a French word that means the fashionable or frequent value which occurred in the set. In simple words, we can say that the mode is the value which has the highest occurrences. For the direct method, we can calculate directly by seeing itself. For the continuous method, there is a particular formula to find out the value of mode.

5. Relative position of arithmetic mean, median, and mode

The NCERT solutions of Class 11 Statistics Chapter 5 have also explained the students about the positions of three measures of central tendency. If we can stir the magnitude of three measures in any direction, the median should be in the middle. Mode and the arithmetic mean will be at either of the extreme positions.

6. Conclusion

Thus the Chapter 5 of measures of central tendency has been explained very well by professional teachers to the students. The material is provided with different examples of all six concepts.

FAQs on NCERT Solutions for Class 11 Statistics Chapter 5 - Measures Of Central Tendency

1. Find the mean, median, and mode for the following list of values:

13, 18, 13, 14, 13, 16, 14, 21, 13

The mean is the usual average is,

(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15

The median is the middle value, so first, we have to rewrite the list in numerical order:

13, 13, 13, 13, 14, 14, 16, 18, 21

There are nine numbers in the list, so the size is an odd number.

13, 13, 13, 13, 14, 14, 16, 18, 21

Hence, the median is 14.

A mode is a number that is repeated more times.

Hence, 13 is the mode.

2. What is the difference between Mean and Median?

Mean is the average of all the values given in the set. On the contrary, the median is the exact middle number when a list of values will be written in order. So both are completely different and how they have unique advantages in the field of Statistics.

3. What are the concepts covered in Chapter 5 of Statistics Class 11?

The Chapter 5 deals with 'Measures of Central Tendency' and the statistical concepts like central tendency, statistical averages, etc. The concepts covered in the chapter are:

Central Tendency
Types of statistical averages: Mathematical and Positional
Arithmetic mean and its types
Methods of Calculating Arithmetic Mean
Median and Mode
Quartiles and Percentiles

All these concepts are discussed in a student-friendly language in NCERT Solutions drafted by experts available on the official website of Vedantu and the Vedantu app.

4. What are the important formulae in Statistics Chapter 5 For Class 11?

Formulae form a very important and unavoidable part of this chapter of Statistics because statistical problems do not exist without formulae. As such, students of class 11 need to remember some important formulae if they are to solve problems from this chapter. The formulae are listed out below, and students can refer to NCERT Solutions for this chapter for an easy understanding of these formulae to solve problems.

Arithmetic Mean, X=x1+x2+x3+…+xn/N or ∑x/N
Weighted Mean, XW=∑WX/∑W
Median, M=Size of [N/2]th term+Size of [N/2+1]th term/2
Mode, Z=L1+ (f1-f0/2f1-f0-f2)xi

5. What are the benefits of using NCERT Solutions for learning Statistics Chapter 5 in Class 11?

NCERT Solutions for Statistics Chapter 5 is available all over the internet in PDF formats, the best being solutions provided by Vedantu.

6. What are the definitions of Median and Mode in Class 11 Statistics?

In a given data set, median is that statistical data that gives the value of the variable dividing the group into two equal parts. On the other hand, the mode of a given data set is the value of the variable occurring the most number of times in the series of data values.

7. What are quartiles and percentiles in Chapter 5 of Class 11 Statistics?

A quartile is a statistical term where a series is divided into four equal parts. The end value of each of these parts forms a quartile. A percentile is a statistical term used to show the division of the series into 100 equal parts.
