Rather, you present the trends and relationships that data reveal. In other words, you report the information you have gained by analyzing the data.
To understand this difference, see the following explanations and examples. Important Note: Some instructors may ask you to include the raw data in the results section.
At other times, you will be asked to place the raw data you have in the appendix at the end of the report.

Example: In a study of student test score trends in high school math, students’ individual scores are the raw data. What is information?When you analyze data—process, organize, and present the facts in a way that is useful—then you have created information.

To determine what visual to use, try using the following steps:Ask yourself the following questions:Are the independent and dependent variables qualitative or quantitative? How many data points do you need to show? Are you working with more than one independent variable? In your visual, do you need to show the statistical distribution of the data? How important is it that your readers see individual values? How important is it that your readers see and understand the overall trend? Consider common reasons for using tables and graphs:Tables work best when the readerrequires precise valuesGraphs work best when the writerwants to show a relationship among many valuesIf you’re having trouble deciding what kind of graph or table to use, ask your instructor or consult your school’s writing centre.

Direct readers to notice what is important to see in the visual (a trend? a particular relationship?).
Remember that visuals don’t speak for themselves. Readers need to understand why the visuals are there and how to read them.
Show readers the calculations you made based on the data. You don’t need to include every calculation for each value.
