1. A survey was conducted by a group of students as a part of their environment awareness program, in which they collected the following data regarding the number of plants in 20 houses in a locality. Find the mean number of plants per house.

4. Thirty women were examined in a hospital by a doctor, and the number of heartbeats per minute were recorded and summarised as follows. Find the mean heartbeats per minute for these women, choosing a suitable method.

5. In a retail market, fruit vendors were selling mangoes kept in packing boxes. These boxes contained varying number of mangoes. The following was the distribution of mangoes according to the number of boxes.

3. The life insurance agent found the following data for the distribution of ages of 100 policy holders. Calculate the median age, if policies are given only to the persons whose age is 18 years onwards but less than the 60 years.

6. 100 surnames were randomly picked up from a local telephone directory and the frequency distribution of the number of letters in the English alphabets in the surnames was obtained as follows:

Locate the point 17.5 on the y-axis and draw a line parallel to the x-axis cutting the curve at a point. From the point, draw a perpendicular line to the x-axis. The intersection point perpendicular to x-axis is the median of the given data. Now, to find the median by making a table.

Class 10 Maths Chapter 14, Statistics, is one of the most important chapters present in the textbook. The weightage of this chapter in the CBSE exam is around 11 to 12 marks. On average, there will be 3 questions which could be asked from this chapter and marks will be distributed in a manner of 3+4+4 (it could vary as per question).

The world is highly data-oriented, in fact, each and every field has a group of data, which represents the relevant information. Statistics is the branch of mathematics which deals with the representation of data in a meaningful way.

You will face many real-life scenarios where the fundamentals of statistics are used to represent a set of data in tabular form, in graphs or in pie charts. There are a number of methods you will learn from this chapter such as, step deviation methods, finding mode and median of grouped data, converting frequency distribution and the relation between mode, mean and median methods, etc. 10th Class NCERT solutions are the best study materials to prepare for the CBSE exam.

NCERT Solutions for Class 10 Maths Chapter 14 Statistics deals with the classification of ungrouped as well as grouped frequency distributions. In the previous classes, the students must have learned how to represent the data pictorially in various graphical formats such as bar graphs, histograms, and frequency polygons. They must be familiar with topics like numerical representatives of ungrouped data and measures of central tendencies such as mean, median, and mode. In the NCERT Solutions Class 10 Maths Chapter 14, learning will switch to all the three measures such as mean, median, mode from ungrouped data to the grouped data.

NCERT Solutions Class 10 Maths Chapter 14 Statistics enables the students to understand the concept of statistics by outlining its key points. This chapter also helps in the revision of concepts such as mean, median, mode. Apart from this, the students will be able to explore some new topics with the help of this chapter, such as measures of central tendency in the ungrouped data. The following links mentioned below will help understand the sections in this chapter further in detail :

NCERT Solutions Class 10 Maths Chapter 14 Statistics forms the perfect study material for class 10 students to prepare for their board exams. With detailed explanations on the various methods of the step-deviation method, assumed mean method, direct method, etc., these solutions cover all the important points in a detailed step-by-step manner. A section-wise detailed analysis of NCERT Solutions class 10 chapter 14 Statistics can be seen below :

Topics Covered: The Class 10 maths NCERT solutions Chapter 14 Statistics covers a variety of topics such as mean, median, and mode of grouped data, cumulative frequency, representation of cumulative frequency data in the graphical form, and obtaining the median of grouped data.

NCERT Solutions Class 10 Maths Chapter 14 Statistics deals with the collection, analysis, presentation, and interpretation of data in different forms. This chapter enables the students to arrange data in a particular form in order to study the salient features of the same and present them in a way that can be easily understood by all. The modern world is highly inclined towards studying and analyzing data in order to make the right decisions, be it in any field, thereby these solutions become an important resource to study.

There are a total of 25 questions in NCERT solutions class 10 maths Statistics. All the questions are curated to cover all the topics related to statistics, such as finding the mean, median, mode using different methods, cumulative frequency representation, etc. in detail. A consistent practice of all the examples and questions in the chapter will result in a better understanding and increased confidence in problem-solving. Thus, it is highly beneficial for the students to practice all the questions.

NCERT Solutions Class 10 maths chapter 14 consists of a total of 25 questions distributed in 4 exercises. These questions challenge the students to think out of the box and solve complex problems based on the frequency distribution table, exclusive or continuous frequency, range, etc. Practicing all the questions in these NCERT solutions class 10 maths chapter 14 will result in an excellent preparation for board exams.

Some of the important formulas of this chapter is the mean of grouped data using the direct method, mean method, and step deviation method. Other formulas include median and mode for grouped data. These formulas can better be understood by solving questions in a stepwise manner. The derivation of these formulas is stated in the NCERT Solutions Class 10 Maths Chapter 14.

NCERT Solutions Class 10 Maths Chapter 14 will help you revise the numerical representation of ungrouped data, also known as the measures of central tendencies called mean, median, and mode. Along with that, these solutions also cover the concept of cumulative frequency, the cumulative frequency distribution, and steps involved in drawing \u2018ogives\u2019 or cumulative frequency curves.
