By analyzing and interpreting the data, we can make informed decisions about the data. Students are already familiar with graphical and tabular data. Not only that, but they have also learned the arithmetic mean, the median and mode of central tendency. In NCERT solutions class 11 maths chapter 13, students are now taught about how the collected data is dispersed or how much data is grouped around a measure of central tendency. In NCERT solutions class 11 maths, you will explore the statistical measures like mean deviations, standard deviations, and variances of grouped and ungrouped data in more detail. There are several formulas mentioned in this chapter to find the values of these concepts. NCERT Solutions for class 11 maths chapter 13 Statistics uses lots of practical examples and exercises to give a powerful lesson, so that all students of any intelligence level can get a solid statistics basis.

Important Topics covered in Chapter 13  Statistics
Chapter 13 statistics contains many important concepts that are necessary for the comprehension and application of statistical techniques. Here, we will explore some of the most important concepts in this chapter, which will provide you with an insight of statistics.
13.1 Introduction 

13.2 Measure of Dispersion 

13.3 Range 

13.4 Mean Deviation 
13.4.1 Mean deviation for ungrouped data 13.4.2 Mean Deviation for grouped data 13.4.3 Limitations of mean deviation 
13.5 Variance and Standard Deviation 
13.5.1 Standard deviation 13.5.2 Standard deviation of a discrete frequency distribution 13.5.3 Standard deviation of a continuous frequency distribution 13.5.4 Shortcut methods to find variance and standard deviation 
13.1 Introduction  This section discusses the concepts of the central tendency, the mean and the median (during even and odd numbers of observations) with illustrative examples. It also introduces the concepts of measure of dispersion. Mean, median and mode are measures of the central tendency of the values clustered around the center or center of the distribution.
13.2 Measure of Dispersion  In this section, the following measures of dispersion are defined: range, quartile deviation; mean deviation; standard deviation.
Measure of dispersion helps explain the relation between central tendency and measure of dispersion. For example, a measure of dispersion tells us how well the mean represents the data  if the spread is too big, then the mean does not represent the data.
13.3 Range  In this section, you will find the definition of the range, the formula for the range and examples. Range indicates the variation of scores based on the max and min values in the set.
13.4 Mean Deviation
13.4.1 Mean deviation for ungrouped data
13.4.2 Mean deviation for grouped data
13.4.3 Limitations of mean deviation
In this section, we define the formula for the mean deviation.
Here, you will also learn how to get the mean deviation for ungrouped data and how to get the mean deviation for discrete frequency distributions and the mean deviation for continuous frequency distributions with solved examples.
13.5 Variance and Standard Deviation
13.5.1 Standard deviation
13.5.2 Standard deviation of a discrete frequency distribution
13.5.3 Standard deviation of a continuous frequency distribution
13.5.4 Shortcut method to find variance and standard deviation
This section includes the definition of variances and standard deviations, the formula and solved discrete and continuous distribution examples. Also, In this section, we'll look at the easiest way to figure out the standard deviation with some examples.
