Answer:
Hii
Step-by-step explanation:
Bar graph is the simplest way to represent a data.
● In consists of rectangular bars of equal width.
● The space between the two consecutive bars must be the same.
● Bars can be marked both vertically and horizontally but normally we use vertical bars.
● The height of bar represents the frequency of the corresponding observation.
- Steps in construction of bar graphs/column graph:
● On a graph, draw two lines perpendicular to each other, intersecting at 0.
● The horizontal line is x-axis and vertical line is y-axis.
● Along the horizontal axis, choose the uniform width of bars and uniform gap between the bars and write the names of the data items whose values are to be marked.
● Along the vertical axis, choose a suitable scale in order to determine the heights of the bars for the given values. (Frequency is taken along y-axis).
● Calculate the heights of the bars according to the scale chosen and draw the bars.
