SECTION TWO : Results

Making sense of your data for yourself and others

Step 1: If you haven't already done so, put your lab data in visual form by creating appropriate tables, graphs, and other figures. Representing your data in a visual format will allow you to identify trends and relationships among variables more easily.

More Help:

  • Establish what types of data you have, quantitative or qualitative.
  • Determine if the data should be represented as a table or a graph.
  • If you decide to use a graph to represent your data, determine which type of graph is one that best represents your data.
  • If a table is the best format for your data, then modify the table you used to collect your data so that it is labeled and organized properly. For more help with tables, go to Designing Tables.
  • If you need help creating a spreadsheet to make a table or graph, go to "Excel Tutorial."

Step 2: Once you have generated visual representations of your data, decide the order in which your tables, graphs, or other figures should be presented in the Results section.

More Help:

If you have multiple data sets, you can arrange your visuals according to one of these methods of ordering:

  • chronological order: if the lab consists of more than one procedure, you can present the results in the order in which you did the procedures, especially if that order provides a useful way of leading the reader through the results.
  • order of importance: arrange the visuals by putting the one that is the most important first and then the others in descending order of importance.
  • order of generality: sometimes it is better to start with the most general representation of the data and then place the more specific ones after that,especially if the specific ones serve to support the broad representation or add more details to it.

Step 3: Review all the data from your experiment. In a sentence or two summarize the overall results of this lab. This is the opening sentence(s) of the Results section.

More Help:

  • In your summary, be sure to focus only on the findings, the data from the experiment. Don’t address the hypothesis.
  • Review the data in your visuals (tables and graphs and other figures). If you have trouble shaping a one- or two- sentence summary, look for a unifying feature among the data sets. This is likely to be the dependent variable. The sentence will be a general statement that summarizes your findings about that variable or related variables.
  • You can start the sentence in several ways: "The results of the lab show that …"; "The data from the experiments demonstrate that…"; "The independent variable X increased as Y and Z were…."

Step 4: In separate paragraphs summarize the finding in each of your visuals--tables, graphs, or other figures. First state the overall relationship or interaction among variables that each visual represents. Then include any specific details from the visual that are important for understanding the results. Refer to your tables, graphs, or other figures as figure or table 1, 2, 3, etc.

More Help:

  • Describe each visual in a separate paragraph. Each paragraph has two parts:
    1. The first sentence gives the general finding for the visual, what it indicates overall, and
    2. The following sentence(s) provides key details from the visual that are important to understanding the experiment (don't include all the details).
  • Refer to your visual(s) in the written part of your Results in one of two ways:
    1. Refer to your visual(s) at the beginning of your findings, for example, "Table 1 shows that the reaction times decreased as the strength of the solution increased." "Figure 3 demonstrates that the mortality rate among riparian mammals adhered to approximately seven-year cycles." (It is also possible to use verbs such as "lists," "displays," "describes," etc.)
    2. Refer to your visual(s) in parentheses at the end of the of your findings. For example, "The reaction times decreased as the strength of the solution increased (Table 1)." "The mortality rate among riparian mammals adhered to approximately seven-year cycles (see Figure 3)." (Ask your teacher which format to use for parenthetical documentation.)

Step 5: Complete the Results by placing all the elements you've written in the proper order: (1) the sentence summarizing the overall data for the lab; (2) the paragraphs of word descriptions for each visual arranged in the order the visuals are presented. Remember that the Results only reports and describes what you observed and collected during your lab. The Results does not explain, discuss, or draw conclusions.

The Results looks like this:

  • Summary of overall findings of lab
  • Paragraph related to visual 1
    1. Sentence of overall finding from visual 1
    2. Sentence(s) with key details from the visual 1
  • Paragraph related to visual 2
    1. Sentence of overall finding from visual 2
    2. Sentence(s) with key details from the visual 2
  • Paragraph related to visual 3
    1. Sentence of overall finding from visual 3
    2. Sentence(s) with key details from visual 3, etc.
