NCERT Solutions for Class 9 Maths Exercise 14.3: Points to Remember

Bar Graphs: A bar graph is a pictorial representation of data in which usually bars of uniform width are drawn with equal spacing between them on one axis (say, the x-axis), depicting the variable. The values of the variable are shown on the other axis (say, the y-axis), and the heights of the bars depend on the values of the variable. 

Histogram: A histogram is a form of representation like the bar graph, but it is used for continuous class intervals. It is a graphical representation of a grouped frequency distribution with continuous classes. Unlike a bar graph, the width of the bar plays a significant role in its construction.

In a histogram, the areas of the rectangles erected are proportional to the corresponding frequencies. However, since the widths of the rectangles are all equal, the lengths of the rectangles are proportional to the frequencies.

Frequency Polygon: A frequency polygon is a form of representation that is drawn by joining the mid-points of the upper sides of the adjacent rectangles of a histogram. A frequency polygon graph is a line graph that represents cumulative frequency distribution data. 

Although frequency polygons are drawn with a histogram, they can also be drawn independently without histograms. This can be done by joining the mid-points of the class intervals used in the data. These mid-points of the class intervals are called class marks.
