Statistical Graphs

Statistical Graphs

This article provides details regarding the concept and development of the statistical graphs and their types, advantages, disadvantages, and applications in numerous fields.

Statistical graphs are a picture of applied mathematics knowledge in graphs or graphics. They assist with the information or data storage and help in statistical data analysis.

Graphs in statistics help simplify applied mathematics. 

Because it may be a picture, it is simple to investigate and interpret the information. There are different types of statistical graphs that are used currently. Bar and column graphs, pie charts, scatter plots, histograms, line graphs, stem and leaf plots, area charts, and frequency tables. These help to store the given statistical data. A statistics graph generator is used to create graphs.

Statistical graphs and their definition

  • Graphs are pictorial representations of information typically employed in maths, physics, chemistry, etc.
  • Statistical knowledge delineated in graphs or graphics is known as applied mathematics graphs.
  • Statistical graphs conjointly give the results of applied mathematics analysis.
  • Statistical graphs don’t give the info in graphic kind solely it should embrace different forms conjointly.
  • An applied mathematics graph relies on various data (link, or node).

Statistical graphs and their types

  • It is a pictorial representation of information on horizontal and vertical bars.
  • It represents the total quantity of observation and knowledge.
  • They are delineated on axes (X-axis and Y-axis).
  • They help us to match multiple sets of information.
  • They are used in representing quantitative data. 
  • They are circular charts that are divided into classes by radial lines.
  • The data is delineated in sectors divided by radial lines. These sectors represent the proportion as an entire.

Histograms

  • A bar chart may be a bar graph that displays the discovered frequencies of information binned (divided into contiguous, equally spaced intervals).
  • Histograms also can show binned response knowledge if you decide on a response variable aside from frequency.
  • The heights of the bars represent the ratio of observations of information.

Scatter plots

 A scatter plot may be a two or three-dimensional plot that shows the common variation of two (or three) variables from a gaggle of observations.

The coordinates of every purpose within the plot correspond to the info values for a single observation.

 Line graphs

  • Line graphs are used to represent continuous data.
  • They are generally used in weather forecasts.
  • They are used to depict quantitative data.

Statistical graphs and their uses

  • Statistical graphs facilitate providing an improved understanding and correct description of analytical knowledge.
  • The graphs modify exploratory knowledge analysis on either the link or the node knowledge.
  • Exploiting these graphs will typically detect distributional patterns of correlations within the knowledge.
  • The graphs will give knowledge filters for network knowledge.
  •  Since all views (tables or graphs) of an information set are coupled, observation choices in one chart are mirrored in all told graphs exploiting that knowledge set.
  • Using the applied mathematics graphs, you’ll be able to selectively filter the observations displayed within the network graphs to uncover necessary relationships between nodes.
  • They help minimise the non-data elements hence making our data more precise and accurate.
  • Statistical graphs help compare data between two compartments or more than two (multiple sets).
  • Bar and column charts help compare data, and pie charts are of great use in business, such as profits and losses of products and shipment across the countries.
  • Line graphs are used in stock markets.
  • These are a part of any presentations that deal with statistical data and help analyse the data or information.
  • Variations in the statistical data can be easily identified and determined in pictorial format.
  • Hence there are many uses for statistical graphs.

Limitations of statistical graphs

  • Oversimplifying the data which misleads the data.
  • We can use it only with continuous data(line graphs).
  • Although they are visually appealing, they may lead to some errors in recognising the data.
  • Bar graphs only show the frequencies and fail to show the main assumptions.
  • We cannot determine the exact numerical and statistical data in a pie chart.
  • We can use scatter plots for small datasets, but it is hard to visualise for large datasets.
  • Box plots are not visually appealing compared to others; hence, they are not much effective.
  • These are some of the limitations or disadvantages of using statistical graphs, and they need to be observed keenly to avoid errors and misleading the statistical data.                            
  • It is well known that statistical graphs are employed in various fields with various applications.
  • Statistical graphs help to delineate knowledge and build it additional economically.
  •  Medical Studies- To store the medical records, patient details, their disease, and diagnosis.
  • Weather forecast-collect and store the weather forecasts of different places or regions.
  • Stock markets-census, stock markets of different companies are organised and interpreted.
  • Quality management- collects the data on various products’ quality and analyses the data.
  • Consumer merchandise – stores the information about transports of goods(imports and exports across the country and world).

Conclusion

Hence, statistical graphs are employed to decipher and analyse the applied mathematics knowledge that is useful, making our work more economical. They assist in presenting advanced knowledge in a very appropriate tabular, represented, and graphic kind for a straightforward and clear comprehension of the info. 

Statistical graphs help us make quantitative observations and help to compare the data or information from different sources. It is easy to understand the statistical data as they are visually appealing. Using a statistics graph generator, we can generate these types of graphs.

Statistics helps draw valid inferences, in conjunction with a life of their dependability regarding the population parameters from the sample knowledge.

Despite having disadvantages or limitations, statistical graphs are used frequently in any projects, presentations, etc. Population growth is also depicted through statistical graphs(exponential growth ). Our country’s stock market is determined through these graphs. Frequency distribution or tables are popularly used for organising the frequencies collected from surveys. Cumulative frequency distribution is also used recently.

Hence, statistical graphs and their types are of great importance in our daily life.
