Introduction to Bar Graph and Its Properties

Q. The reason why sometimes Bar Graphs are preferred over pictographs is:

1. Pictures are not as interesting as bars in a bar graph.
2. Sometimes the scale is not clear to understand the data in the pictograph.
3. In a pictograph, one needs to count all the symbols/icons and then multiply with the scale factor whereas in a bar graph, one has to read the value written next to the bar.
4. There is no such preference

Q. Choose the correct property of Bar Graphs from the following:

1. Every bar in the graph should be of equal width.
2. The distance between any two adjacent bars may not be equal.
3. All bars should be of equal height.
4. Bars in the graph could be of different widths.

Q. The reference line on a graph that runs vertically through zero is called the:

1. X axis

Q. The reference line on a graph that runs horizontally through zero is called the:

1. straight line
2. Y axis
3. diagonal
4. X axis
