## 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.
