Lab Report Outline

There are a few lab reports, which are as easy as jotting down outcomes and key findings on a piece of paper. However, other reports are in the form of filling forms, demanding you to fill up the sections with the requested data. Moreover, there are also some reports that are lengthy documents comprising several sections. Here is the standard lab report format, highlighting the important parts of a lab report.

Lab Report Format

Title page, abstract, citations and appendices are asserted on a separate page. Other formatting rules include:

Double-spacing of the text

12 font size

Page numbers

The report includes a number of arguments that link the introductory section to the rest of the body.

Lab Report Title Page

A lab report usually comprises a title page, clearly identifying the lab. Your lab report title should be precise and descriptive, but not terse, wordy or too verbose.

Furthermore, include your name, date and any other piece of information on your title page, which is crucial to identify the lab. Also, include the variables under investigation but not in the form of a question.

Lab Report Abstract

Abstract of a lab report includes a brief summary of the entire report. It is about 50–150 words, usually, depending on your topic. It can be arranged and ordered in many ways. State the purpose of the experiment and your goal.

It briefly mentions all the procedures, designs, experiments, reports, surveys, questionnaires and the main findings. There are few abstracts that report the results first: it depends on the significance of the findings.

Also, describe the participants and setting i.e. who, when, where, how many, what groups? Mention any relevant statistics to support the study if required.

Lab Report Introduction

If you’re wondering how to write an introduction for a lab report then pay close attention to this section. The introduction specifies the purpose of your study and lab. This is the section where you will specify your hypothesis as well. Provide background information, how you developed the hypothesis and your aims of the study.

You must tell your readers how you came up with your study, how you used the work of other scientists. Highlight if your work is based on other research, etc.

Ideally, an introduction should have a funnel structure i.e. it should start broad and then become more specific. Furthermore, providing this background will help the reader to evaluate your work much better.

An introduction template is something like:

  • Brief information on the topic, a general theory.
  • Highlight specific research.
  • Explain the theoretical framework
  • Transition
  • Relevant details.
  • Summarize previous studies
  • Rationale
  • Hypothesis
  • Aims explaining what you want to achieve and why?

Make sure that you are only highlighting information absolutely necessary for your topic and study. Remember that you are writing a lab report and not a complete essay.

Equipment List

Your readers may require and expect you to mention all the equipment or material used while testing or given in the lab manual. You need to mention the name and the number of equipment. Listing of equipment guarantees that you are using the same equipment in your testing process.

Before listing this piece of information, check with your instructor first, to confirm whether you’ll have to add this particular information in your report or not. If you are required to list down the materials used, do them in a way that the reader can easily replicate your study.


In this section, you will mention the exact steps that you followed while performing your experiment. Make sure you provide sufficient details, imagine that the reader is a complete lay person with zero knowledge.

This experimental procedure should be written thoroughly, step by step and in simple words so that any third person can duplicate it while performing his own experiment.

You can start by highlighting how the apparatus was set up. You may do this with the help of a diagram.

Then enlist the materials.

How you gathered the data.

Any complications that might have occurred and how did you overcome them?

You can also include figures or flow charts to make this section simple and helpful.

In this section, you will use the following subheadings.


Here the writer has to discuss the participants of the research by the following aspects:

  • How many participants were recruited?
  • How did you obtain your sample?
  • Provide relevant demographic details, e.g. gender, ethnicity, age, etc.


Discuss the independent and dependent variables of your research study. Make sure the independent variables are specified separately.


Make a list of all the materials and measures that include the title and nature of the questionnaire. Also, illustrate the examples of questionnaire items.


The numerical raw data that is obtained from your experiment is represented in a table form.

The main purpose of data is to show what you observed while doing the experiment. Always keep in mind that data is a compilation of facts, so do not interpret it.

Graphs and Figures

Graphs and figures must be labelled with a descriptive title. Don’t forget to mention the scientific units of measurements.

Write the independent variable on X-axis and dependable variable on Y-axis. Also, refer to the graphs and figures in the text of your report.

For instance, the first figure should be Figure 1, the second should be figure 2 and so on.

The title should be written below the graph and to place the title above the table.

Discussion or Analysis

In the lab report discussion section, data calculations are done and data is interpreted to determine whether your hypothesis was proved or not.

You can also discuss any mistakes you made while conducting your experiment in plain English. Also, compare the results to the background materials along with its implications.

In addition, you can propose further points for the success of future experiments.


Include references only when your experiment is based on some previous research.

Also, if you have included facts in your report, then also you should list references. It will include all the sources of your essay in alphabetical order. The best form of citation that is mainly used includes the APA Style.

Refer to the following referencing format.


Author, A. A. (year). Title of work. Location: Publisher.

Journal Articles

Author, A. A., Author, B. B., & Author, C. C. (year). Article title. Journal Title, volume number(issue number), page numbers

1.1.12 Results

In this part, you report about the results of tests in the form of descriptive and inferential statistics. You tell your readers about the measured test with exact data. You may also add equations or calculations along with the magnitude.

Furthermore, this part may or may not require data interpretations. It depends upon the instructions of your professor; he may expect conclusions or interpretations to be added in separate headings. So, for this part, check with your instructor/professor first.

A lab report’s conclusion is dedicated to the results of the test and its interpretation. In this section, you may draw indications from the outcome and the methods that are used to achieve them. Always end it with the statement of your findings.
