In this section move from the results to the theory. Many beginning science students neglect to do so and find themselves struggling to remember precisely which variables were involved in the process or in what way the researchers felt that they were related. Figures How do I include figures in my report?
So when you write your Methods section, keep in mind that you need to describe your experiment well enough to allow others to replicate it exactly. Did you all get the same results? Your name and the names of any lab partners.
Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it. For example, many writers find that composing their Methods and Results before the other sections helps to clarify their idea of the experiment or study as a whole. You can learn more in our handout on passive voice.
Because the Results can seem so self-explanatory, many students find it difficult to know what material to add in this last section. Then you can show more clearly why you believe your hypothesis was or was not supported.
You might begin this part of the Discussion by explicitly stating the relationships or correlations your data indicate between the independent and dependent variables.
Many editors of professional scientific journals prefer that writers distinguish the lines in their graphs by attaching a symbol to them, usually a geometric shape triangle, square, etc. The dependent variable the one you are measuring is on the Y-axis.
