Answer 1

Answer:

1)Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a horizontal or vertical rectangular bar that levels off at the appropriate level. There are many characteristics of bar graphs that make them useful.

2)A simple bar chart consists of a grid and some vertical or horizontal columns (bars). Each column represents quantitative data. There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs.

3)Diagrammatic presentation is a technique of presenting numeric data through Pictograms, Cartograms, Bar Diagrams & Pie Diagrams etc. It is the most attractive and appealing way to represent statistical data. Diagrams help in visual comparison and have a bird's eye view.

4)There are two types of bar diagrams namely, Horizontal Bar diagram and Vertical bar diagram. While horizontal bar diagram is used for qualitative data or data varying over space, the vertical bar diagram is associated with quantitative data or time series data.

5)In a pie chart, the various observations or components are represented by the sectors of a circle and the whole circle represents the sum of the value of all the components . Clearly, the total angle of 360° at the center of the circle is divided according to the values of the components .
