Answer 1

The two commonly used graphs,charts or table as follows

a.Bar graph
It is drawn based on x-y graph where both the horizontal and vertical bars have different values.Also for Bar graph the size,length also represent respective values.It is mainly used for non continious data.

The main advantages of bar graph is that

a.It can represent the data which can change over time
b.It represents data for each category in a frequency distribution

The disadvantages of bar graph are as follows

a.It can be manipulated very easily to give false information.
b.Sometimes for Bar graph it is required to explain separately.

b.Pie Charts
It is mainly when we have to display proportions and percentage between different categories.The individual arc in the chart represents a category.The full circle represent the total data or the 100% data.

The main advantage of pie chart are as follows

a.It is mainly used when to represent a fractioal part of the data from whole.
b.IT is a best of speaking for the uninformed audience

The main disadvantage of pie chart are as follows

a.Pie chart becomes less effective if too many values are used.
b.Multiple data sets are required to compare for one value.
