In addition, all tables and figures must have numbers, titles and legends. Figure and Table Legends Legends to the figures and tables explain the elements that appear in the illustration.

Writing a experimental procedure

How to write the methods section of a research paper.

Therefore, it requires a clear and precise description of how an experiment was done, and the rationale for why specific experimental procedures were chosen. The methods section should describe what was done to answer the research question, describe how it was done, justify the experimental design, and explain how the results were analyzed.

Scientific writing is direct and orderly. Therefore, the methods section structure should: Once all elements of the methods section are written, subsequent drafts should focus on how to present those elements as clearly and logically as possibly. The description of preparations, measurements, and the protocol should be organized chronologically.

For clarity, when a large amount of detail must be presented, information should be presented in sub-sections according to topic.

Material in each section should be organized by topic from most to least important. Introduction The methods section is the most important aspect of a research paper because it provides the information by which the validity of a study is ultimately judged.

Therefore, the author must provide a clear and precise description of writing a experimental procedure an experiment was done, and the rationale for the specific experimental procedures chosen. It must be written with enough information so that: Basic Research Concepts The scientific method attempts to discover cause-and effect relationships between objects ie, physical matter or processes.

In the physical sciences objects are regarded as variables, and a variable is anything that can assume different values. Elucidating a cause-and-effect relationship between objects requires that variables are classified as independent, dependent, or confounding.

An independent variable is one that, when manipulated, causes a change in another variable. The variable that changes in response to that manipulation is referred to as a dependent variable.

For example, intraocular pressure is a dependent variable that responds to manipulations in independent variables such as blood pressure and pupil size. A confounding or extraneous variable is anything other than the independent variable of interest that may affect the dependent variable.

Therefore, a change in a dependent variable may be due wholly or in part to a change in a confounding variable.

For example, a change in vena cava pressure can alter intraocular pressure by its effect upon ocular blood drainage. Evaluation of a potential cause-effect relationship between 2 objects is accomplished through the development of the study design. A study design is simply a strategy to control and manipulate variables that provide an answer to the research question regarding potential cause-and-effect relationships.

Validity refers to the credibility of experimental results and the degree to which the results can be applied to the general population of interest. Internal validity refers to the credibility of a study and is determined by the degree to which conclusions drawn from an experiment correctly describe what actually transpired during the study.

The internal validity of a study is judged by the degree to which its outcomes can be attributed to manipulation of independent variables and not to the effects of confounding variables. Therefore, the study protocol must be designed to control eg, to keep constant as many extraneous factors as possible so that any potential cause-and-effect relationship between 2 objects can be judged accurately.

It is importantto emphasize that confounding variables can never be fully controlled.

How did you study the problem?

Furthermore, the influence of these variables may not be fully appreciated by those conducting the research. External validity is primarily determined by how subjects are selected to participate in a study and by the use of randomization procedures that limit potential bias in how subjects are assigned to treatment groups.

The complexity of scientific inquiry necessitates that the writing of the methods be clear and orderly to avoid confusion and ambiguity. First, it is usually helpful to structure the methods section by: Describing the materials used in the study 2.

Port, February 23, Writing an experiment report is a very stylized genre of writing. The introduction and experimental procedure can (and should) be completed before you come to lab. During lab, make note of any deviations from your procedure as you perform the experiment, then indicate them in your experimental write‑up.
