Outline of and justification for the theoretical perspectives informing the research and the methodological approach The following two paragraphs provide the details of how the researcher gathered data for that part of the research that looked at classroom interactions. There is no need to reiterate every detail, unless you deviated from the source and changed a step in your procedure. The past tense is more appropriate in this section because the experiment already happened.

Your graph might look something like the one in Figure 1. Experiments can have only one independent variable. Present the results of your experiment s in a sequence that will logically support or provide evidence against the hypothesis, or answer the question, stated in the Introduction. For example, if you are growing plants, you can put three identical plants or seeds in three separate pots and that would count as three trials. However, the most common figure, particularly for undergraduates, is the line graph, so this is what we will focus on here.

The scientific method allows experiments to be duplicated and results to be communicated uniformly. A hypothesis is a testable explanation of an observed occurrence in nature, or, more specifically, why something you observed is occurring. How did I solve the problem? Your procedure should be explained explicitly enough, in a step-by-step fashion, so that others can perform the exact same experiment that you performed, allowing them to test the validity of your results. The control group consists of all those trials where you leave the independent variable in its natural state.
