Experts created the RD Sharma solution to help students understand and solve chapter 24 math problems while also helping students in grasping the fundamentals. The RD Sharma solutions for class 8 maths will help students improve their math abilities and prepare for examinations by using these solutions. Students can benefit from RD Solution for class 8 since it has solved questions and elaborate explanations.

Students will be required to understand the concept and answer questions in Exercise 24.2 of the RD Sharma textbook. To give you a quick revision of what you must have learned in previous classes, you have learned graphical representation in the form of bar graphs which represent the frequency distribution of ungrouped data. In class 8, you will learn about another graphical representation known as Histogram. To learn quickly you can download a Free PDF of RD Sharma Class 8 Solutions Chapter 24 - Graphical Representation of Data As Histograms Exercise 24.2.

In this chapter, students will learn in detail about Histograms. A histogram is a form of a graph with several statistical uses. Histograms show the number of data points that fall inside a certain range of values, allowing for a visual explanation of numerical data. These value ranges are referred to as classes or bins. The usage of a bar depicts the frequency of data that falls into each category. The bigger the bar, the more data values in that bin occur often.

In the above image, you can see how histograms are drawn. The X-axis represents the class intervals and the Y-axis represents the frequency. Always remember that it is very important to mention Scale with every histogram. To practice these skills, you can download PDF for free. Here are some examples for your reference:

1. Given Below is The Frequency Distribution of The Heights of 50 Students of a Class:

Class Interval :	140 - 145	145 - 150	150 - 155	155 - 160	160 - 165
Frequency	8	12	18	10	5

Solution:

The class limits are represented along the x-axis on a suitable scale and the frequencies are represented along the y-axis on a suitable scale. Taking class intervals as bases and the corresponding frequencies as heights, the rectangles can be constructed to obtain the histogram of the given frequency distribution as shown in the figure below:

2. Draw a Histogram of The Following Data :

Class Interval :	10 - 15	15 - 20	20 - 25	25 - 30	30 - 35	35 - 40
Frequency	30	98	80	58	29	50

Solution:

The class limits are represented along the x-axis and the frequencies are represented along the y-axis on a suitable scale. Taking class intervals as bases and the corresponding frequencies as heights, the rectangles can be drawn to obtain the histogram of the given frequency distribution. The histogram is shown below:

FAQs on RD Sharma Class 8 Solutions Chapter 24 - Graphical Representation of Data As Histograms (Ex 24.2) Exercise 24.2

1. What is the difference between a bar graph and a histogram?

Bar graphs and histograms are different because the level of data measurement varies in these types of graphs. The bar graph depicts the nominal level of value whereas the histogram depicts the ordinary level of value. Secondly, the classes for a bar graph are these categories, and bar graphs assess the frequency of categorical data. On the contrary, histogram classes are value ranges. Another key difference, It is usual practice to rearrange the bars in a bar graph in order of decreasing height. However, histogram bars cannot be rearranged. They must be arranged in the sequence in which the classes take place.

2. Do bar graphs and histograms look similar?

Yes, at first glance they look identical as vertical bars are drawn in both cases. These vertical bars are used to depict data in both graphs. The relative frequency of the quantity of data in the class is represented by the height of a bar. The taller the bar, the more frequently the data is collected. The smaller the bar, the less frequently data is collected. However, appearances can be misleading. The similarities between the two types of graphs disappear at this point.

3. In which field can we use histograms?

Histograms are often used for probability. Discrete Probability Distributions can be depicted with the help of a histogram. In order to make a histogram, first, you select a class. The height of the bars that you will make shows the possible probability of each outcome. The width of each class should be one unit. The areas of the bars show the probability. A histogram can also be used to show a data set to compare the frequency of occurrence of quantitative data.

4. Why is it better to refer to RD Sharma?

The teaching pattern at the school is taken into consideration in order to explain the answers in a clear and precise manner. In addition to making the answers easier to understand, the language used to define the vocabulary has been simplified. The usage of difficult-to-understand terminologies has been avoided, and obstacles have been broken into simple techniques.
