**You can use different type of graphs to show a data.**

Examples: Bar graphs, double bar graphs, circle graphs, line graphs and pictographs

__Bar Graphs__:

*Best for comparing across categories. It is a graph where the length of a bar represents a certain amount.*

*It can be easily 2-3 data sets and it's visually strong.*

Disadvantage:

*Graph categories can be reordered to emphasize certain effects and can use only with discrete data.*

__Double Bar Graphs:__

*Best for comparing two sets of data across categories. It is*

*chart with rectangular bars with lengths proportional to the values that they represent.*

Advantage:

*B**eautiful and neatly constructed diagrams/charts are more attractive then**simple figures*

Disadvantages:

*Can be tempting to compare too many things, graph becomes convoluted**and difficult to understand. Limited space for labelling with vertical bar graphs*

Circle Graph:Best for comparing categories to the whole using percents. Itused to compare parts and show their relationship to a whole. These work well for showing percentages and fractions.

Advantage:Visually appealing, Shows percent of total for each category

Disadvantage:No exact numerical data and it is hard to compare 2 data sets.

Line Graph:Best for showing changes over time.. It is a graph thatuses line segments to show changes in data; the data usually represents a quantity changing over time.

Advantage:Can compare multiple continuous data sets easily

Disadvantage:Use only with continuous data

*
*

Pictograph:Best for comparing data that can be easily counted and represented using symbols. It isa graphic character used in picture writing.

Advantages:Easy to read, Visually appealing

Disadvantages:Hard to quantify partial icons, Icons must be of consistent size

Watch to learn:
