NCERT Solutions for Class 10 Maths Chapter 14 Statistics
In our previous class, we have studied the classification of the given data into grouped and ungrouped frequency distributions and learned to represent given data in the form of graphs such as histograms, bar graph, etc and mean mode and median. In NCERT Class 10 Maths Chapter 14 Statistics, we will extend the study of measures of central tendency, namely, mean, mode and median from the ungrouped data to that of grouped data. In this chapter, there are 4 exercises with 25 questions. These NCERT solutions are the detailed explanation of NCERT textbook of class 10 maths. And these solutions help students in their preparation of CBSE Class 10 Board exam.
Today's world highly depends on data. Each and every sector have a group of data which represents various information. Statistics is the branch of applied mathematics which deals with the collection of data and represent it in a meaningful way. In NCERT Class 10 Maths Chapter 14 Statistics we will also study the concept of cumulative frequency, it's distribution and how to draw cumulative frequency curves. Students face many reallife problems where the fundamentals of statistics are used to represent data in graphs or in tabular form. There are a number of methods and concepts we will learn from Chapter 14 Statistics such as finding median and mode of grouped data, step deviation methods, converting frequency distribution and the relation between, mean, mode and median methods, etc.
To find the mean for grouped data
(i) The direct method 

(ii) The assumed mean method 

(iii) The step deviation method
