Graphs and charts are visual aids that let you lot to convey information and statistics to your audience during a presentation. Different types of graphs can be used, depending on the information you are conveying. While each features advantages and disadvantages, some common benefits exist. Graphs make the data more disarming and provide a mode to appoint your audition during your presentation. Let'due south explore some of the main graphs that are in apply.

Pie Chart or Circumvolve Graph

A pie chart is a graph that features a circle cutting into different sectors or "pie slices." For this reason, they are also called circle graphs. Each sector stands for a relative size of value for a whole, with proportionate sizing for the quantity information technology represents.

Advantages:

Graph can be created proportionally to the quantity it needs to represent
Displays multiple classes of data in one chart
Puts large sums of data into visual form for piece of cake understanding
More visually appealing than other graphs
Offers easy calculations of information accurateness
Requires niggling explanation
Understood easily past dissimilar departments within a business and for media purposes

Disadvantages:

Doesn't reveal exact values
Multiple graphs are needed for time-lapse data
Key assumptions, causes, result, and patterns are non revealed
Manipulated hands, causing false impressions or interpretations

Bar Graph & Pareto Graph

Similar to a pie nautical chart, a bar graph uses rectangles or narrow columns to testify information comparisons. The meridian of the bar graph that is shaded in represents unlike amounts. The starting time known utilise of bar graphs was in 1917. A Pareto graph or nautical chart is a blazon of bar graph that also features a line graph.

Advantages:

Each data category is displayed in a frequency distribution blueprint
Allows for visualization of relative numbers or proportions of multiple categories
Piece of cake summarization of large sets of data
Clearer understanding of trends over table charts
Offers estimated values of key factors at a glance
Gives the power to check the accuracy of calculations visually
Easy for multiple levels within a company or audience to understand the information presented

Disadvantages:

Additional caption is required
Can be manipulated to show imitation results
Unable to show fundamental assumptions, causes, effects, or patterns present

Histogram

First created by Karl Pearson, a histogram is a plot or chart that allows y'all to bear witness the underlying frequency distribution of a continuous set of variables. Often used for carrying statistical data. Different a bar graph, a histogram merely displays a unmarried variable.

Advantages:

Work well for displaying big ranges of data or information
Intervals are always equal, allowing for consistency with data
Easy to transform data from frequency forms to graph forms

Disadvantages:

Impossible to excerpt an exact amount for input
Inability to compare multiple points of information in one nautical chart

Stem and Leaf Plots

Stem and leaf plots are charts that let you lot to carve up data values into a "stem" and "leaf" pattern. This usually consists of putting the offset value into the stem cavalcade and concluding digits into the leaf column. This type of graph is used for showing the frequency of the values that occur.

Advantages:

Provide simplified methods for keeping scores
Easy to utilize and create
Can handle large amounts of information in an organized fashion
Offers the ability to show ranges, minimums, and maximums for numbers apace

Disadvantages:

Not a visually appealing method for interesting an audience
Can become messy and disorganized when a lot of information is added
Longer ranges and variances can be difficult to break down into useful data categories

Dot Plots

Dot plots are graphs used for displaying small sets of data and groups. These charts utilize dots to stand for the frequency of information. Dots are displayed in columns that coincide with certain categories.

Advantages:

Like shooting fish in a barrel to create
Ability to show dissimilar categories in one graph
Doesn't require the use of figurer for creating

Disadvantages:

Non visually appealing
Tin can be hard to read with large amounts of data
Only works well with small sets of information

Scatterplots

A scatterplot is a graph that uses a series of dots to correspond ii different values of data being compared. The position in which dots are placed along the horizontal and vertical lines represent the value for that information bespeak.

Advantages:

Power to use for showing the connection of large amounts of data
Work for well-nigh types of data and subject matters
Provide an accurate flow of information being conveyed

Disadvantages:

Can be difficult for everyone to follow
Easy to manipulate information for false results

Fourth dimension-series Graphs

A time-series graph is a chart that shows data recordings taken at regular time intervals. The fourth dimension is represented on the horizontal admission with waves that prove the recorded data. These types of graphs are often used to show trends and patterns for different categories or subject field matters that exist.

Advantages:

Allows for the understanding of past behaviors and future predictions
Subject matters are identified hands
Offers comparisons of two subjects at the aforementioned time
Gives the ability to follow present performance more than closely

Disadvantages:

Not ever accurate with finding
Factors causing fluctuation cannot always exist adjusted every bit needed
Factors being monitored may not always stay the same over extended fourth dimension periods, causing unreliable data
