The primary step to make evidence-based decisions is gathering accurate data and summarizing, describing, and presenting it for analysis. Graphs are charts through which data is represented as curves or lines drawn across coordinated points. Tables and graphs help to analyze the cause and effect relation between the two variables.
With graphs, you can measure the change in a variable if the other variable changes by a specific amount. They are helpful to study frequency distribution as well as time series because they give out a clear picture of any problem. They are good tools to present and analyze data.

Why Use Graphs and Tables in Statistics?
While presenting ideas, it is useful to make the point with tables or graphs. The visual methods make a point stronger compared to describing data simply. Though they are powerful methods, they can damage a presentation when they convey a wrong message. Appropriate use of tables and graphs can improve the message you deliver.
Graphs and tables are visual representations. These are used for organizing information. Graphs show the information by showing it as shapes, Scientists and researchers use graphs and tables to report findings. In articles, newspapers, and television, they can support arguments or viewpoints.
They are helpful tools because with these tools people can make decisions. Inferences should be made from data. Tables and graphs condense a huge amount of information into easily understandable formats, which effectively and clearly communicate vital points. Line graphs, bar graphs, and pie charts are helpful to display categorical data, Constant data can be measured on a continuum or scale.
Tables is arranging data in columns and data, Using tables is pervasive in communication, data and research analysis. They appear in handwritten notes, print media, traffic signs, computer software, and other places.
They can organize data, which is too complicated or detailed that can be described properly in the text, enabling readers to see the results quickly. These are used for highlighting patterns or trends in data and making a manuscript readable by eliminating numeric data from text. Data tables are used for statistical analysis such as calculation of dispersion and central tendency, etc. The reasons to use tables and graphs are discussed in our Statistical Tables and Graphs assignment help.
