The presentation of data refers to how mathematicians and scientists summarize and present data related to scientific studies and research. In order to present their points, they use various techniques and tools to condense and summarize their findings. These tools include the use of tables, graphs and subsets to provide an overview of their calculations and the data they have mined.
To present a large amount of data in an understandable format, researchers often condense the results into groups. The groupings are referred to as "classes," and the size of each class is called a "class width" or "class size." A class width features a lower class limit and upper class limit. So, in the class 30-39, "30" represents the lower class limit while "39" denotes the upper class limit. This kind of data are condensed into tabular form or subsets for demonstration purposes.
The University of Leicester supports the idea of presenting data using tables. However, according to the school's website, it is essential to consider data arrangement, as well. The site states that most individuals find it easier to comprehend data by reading down columnar featured data rather than by scanning the information across a row. Therefore, it is typically better to underscore research results or calculations in a table's columns. The data should be arranged in accordance to its magnitude.
