What Are the Advantages and Disadvantages of a Graph?
Graphs and charts are visual aids that allow y’all to convey data and statistics to your audience during a presentation. Different types of graphs can be used, depending on the data yous are conveying. While each features advantages and disadvantages, some common benefits exist. Graphs make the data more convincing and provide a way to engage your audition during your presentation. Let’s explore some of the main graphs that are in use.
Pie Nautical chart or Circle Graph
A pie chart is a graph that features a circumvolve 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 it represents.
- Graph can be created proportionally to the quantity it needs to correspond
- Displays multiple classes of data in one chart
- Puts large sums of data into visual form for easy understanding
- More visually appealing than other graphs
- Offers easy calculations of data accurateness
- Requires little caption
- Understood easily by dissimilar departments inside a business and for media purposes
- Doesn’t reveal exact values
- Multiple graphs are needed for time-lapse data
- Key assumptions, causes, effect, and patterns are non revealed
- Manipulated hands, causing false impressions or interpretations
Bar Graph & Pareto Graph
Like to a pie chart, a bar graph uses rectangles or narrow columns to prove information comparisons. The pinnacle of the bar graph that is shaded in represents different amounts. The first known use of bar graphs was in 1917. A Pareto graph or chart is a type of bar graph that as well features a line graph.
- Each data category is displayed in a frequency distribution pattern
- 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 key factors at a glance
- Gives the ability to check the accuracy of calculations visually
- Easy for multiple levels within a company or audience to understand the information presented
- Additional explanation is required
- Tin exist manipulated to show simulated results
- Unable to bear witness key assumptions, causes, effects, or patterns present
First created by Karl Pearson, a histogram is a plot or chart that allows you to show the underlying frequency distribution of a continuous fix of variables. Often used for conveying statistical information. Different a bar graph, a histogram only displays a single variable.
- Work well for displaying big ranges of data or information
- Intervals are always equal, assuasive for consistency with data
- Like shooting fish in a barrel to transform data from frequency forms to graph forms
- Incommunicable to extract an verbal amount for input
- Inability to compare multiple points of data in 1 chart
Stem and Leaf Plots
Stem and leaf plots are charts that allow yous to split data values into a “stem” and “leaf” blueprint. This normally consists of putting the showtime value into the stem column and last digits into the foliage cavalcade. This type of graph is used for showing the frequency of the values that occur.
- Provide simplified methods for keeping scores
- Like shooting fish in a barrel to use and create
- Can handle large amounts of information in an organized fashion
- Offers the ability to prove ranges, minimums, and maximums for numbers quickly
- Not a visually highly-seasoned method for interesting an audience
- Can become messy and disorganized when a lot of data is added
- Longer ranges and variances tin be difficult to break down into useful data categories
Dot plots are graphs used for displaying small sets of information and groups. These charts utilise dots to represent the frequency of information. Dots are displayed in columns that coincide with certain categories.
- Easy to create
- Ability to bear witness different categories in 1 graph
- Doesn’t require the employ of computer for creating
- Not visually appealing
- Tin can be hard to read with large amounts of data
- Only works well with small sets of information
A scatterplot is a graph that uses a series of dots to represent 2 different values of information being compared. The position in which dots are placed forth the horizontal and vertical lines represent the value for that data point.
- Power to apply for showing the connexion of large amounts of data
- Piece of work for nearly types of data and subject matters
- Provide an accurate flow of information being conveyed
- Can exist difficult for anybody to follow
- Easy to dispense data for false results
A time-series graph is a nautical chart that shows information recordings taken at regular time intervals. The fourth dimension is represented on the horizontal access with waves that evidence the recorded information. These types of graphs are often used to bear witness trends and patterns for different categories or subject matters that exist.
- Allows for the understanding of by behaviors and futurity predictions
- Subject matters are identified easily
- Offers comparisons of two subjects at the same time
- Gives the ability to follow present functioning more than closely
- Not always accurate with finding
- Factors causing fluctuation cannot e’er be adjusted as needed
- Factors being monitored may not always stay the same over extended fourth dimension periods, causing unreliable data
