Graphs and charts are visual aids that let you to convey data 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 information more convincing and provide a way to engage your audience during your presentation. Allow's explore some of the chief graphs that are in apply.

Pie Chart or Circumvolve Graph

A pie nautical chart is a graph that features a circumvolve cut into different sectors or "pie slices." For this reason, they are besides called circle graphs. Each sector stands for a relative size of value for a whole, with proportionate sizing for the quantity it 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 like shooting fish in a barrel agreement
More visually highly-seasoned than other graphs
Offers easy calculations of data accurateness
Requires little explanation
Understood easily past unlike departments inside a business and for media purposes

Disadvantages:

Doesn't reveal verbal values
Multiple graphs are needed for time-lapse data
Key assumptions, causes, effect, and patterns are not revealed
Manipulated easily, causing false impressions or interpretations

Bar Graph & Pareto Graph

Like to a pie nautical chart, a bar graph uses rectangles or narrow columns to show data comparisons. The height of the bar graph that is shaded in represents dissimilar amounts. The offset known use of bar graphs was in 1917. A Pareto graph or nautical chart is a type of bar graph that likewise features a line graph.

Advantages:

Each information category is displayed in a frequency distribution design
Allows for visualization of relative numbers or proportions of multiple categories
Easy summarization of large sets of data
Clearer understanding of trends over tabular array charts
Offers estimated values of central 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 data presented

Disadvantages:

Additional explanation is required
Can exist manipulated to bear witness false results
Unable to show central assumptions, causes, effects, or patterns present

Histogram

First created past Karl Pearson, a histogram is a plot or chart that allows you to show the underlying frequency distribution of a continuous set of variables. Often used for carrying statistical information. Unlike a bar graph, a histogram only displays a single variable.

Advantages:

Piece of work well for displaying big ranges of data or information
Intervals are e'er equal, allowing for consistency with data
Easy to transform data from frequency forms to graph forms

Disadvantages:

Impossible to extract an exact amount for input
Inability to compare multiple points of data in one chart

Stem and Foliage Plots

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

Advantages:

Provide simplified methods for keeping scores
Easy to use and create
Tin can handle large amounts of data in an organized style
Offers the ability to show ranges, minimums, and maximums for numbers quickly

Disadvantages:

Not a visually appealing method for interesting an audition
Tin can get messy and disorganized when a lot of data is added
Longer ranges and variances tin be hard to break down into useful data categories

Dot Plots

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

Advantages:

Easy to create
Ability to prove different categories in one graph
Doesn't require the utilise of computer for creating

Disadvantages:

Not visually appealing
Can be difficult to read with large amounts of data
Simply works well with small sets of information

Scatterplots

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

Advantages:

Ability to use for showing the connection of large amounts of data
Work for most types of data and bailiwick matters
Provide an accurate menstruum of information being conveyed

Disadvantages:

Tin can exist difficult for anybody to follow
Easy to dispense information for false results

Time-serial Graphs

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

Advantages:

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

Disadvantages:

Not always accurate with finding
Factors causing fluctuation cannot always exist adjusted equally needed
Factors being monitored may not always stay the same over extended time periods, causing unreliable information
