For biology, psychology and social sciences, there can be a huge variety of methods to choose from, and a researcher will have to justify their choice. Whilst slightly arbitrary, the best way to look at the various methods is in terms of "strength".
Experimental Research Methods
The first method is the straightforward experiment, involving the standard practice of manipulating quantitative, independent variables to generate statistically analyzable data. Generally, the system of scientific measurements is interval
or ratio based. When we talk about "scientific research methods", this is what most people immediately think of, because it passes all of the definitions of "true science". The researcher is accepting or refuting the null hypothesis. The results generated are analyzable and are used to test hypotheses, with statistics giving
a clear and unambiguous picture.
This research method is one of the most difficult, requiring rigorous design and a great deal of expense, especially for larger experiments. The other problem, where real life organisms are used, is that taking something out of its natural environment can seriously affect its behavior.
It is often argued that, in some fields of research, experimental research is "too" accurate. It is also the biggest drain on time and resources, and is often impossible to perform for some fields, because of ethical considerations.
In other fields of study, which do not always have the luxury of definable and quantifiable variables – you need to use different research methods. These should attempt to fit all of the definitions of repeatability or falsifiability, although this is not always feasible.
Opinion Based Research Methods
Opinion based research methods generally involve designing an experiment and collecting quantitative data. For this type of research, the measurements are usually arbitrary, following the ordinal or interval type.
Questionnaires are an effective way of quantifying data from a sample group, and testing emotions or preferences. This method is very cheap and easy, where budget is a problem, and gives an element of scale to opinion and emotion. These figures are arbitrary, but at least give a directional method of measuring intensity.
Quantifying behavior is another way of performing this research, with researchers often applying a "numerical scale" to the type, or intensity, of behavior.
By definition, this experiment method must be used where emotions or behaviors are measured, as there is no other way of defining the variables. Whilst not as robust as experimental research, the methods can be replicated and the results falsified.
Observational Research Methods
Observational research is a group of different research methods where researchers try to observe a phenomenon without interfering too much.
Observational research methods, such as the case study, are probably
the furthest removed from the established scientific method. This type is looked down upon, by many scientists, as "quasi-experimental" research, although this is usually an unfair criticism. Observational research tends to use nominal or ordinal scales of measurement.
Observational research often has no clearly defined research problem, and questions may arise during the course of the study. For example, a researcher may notice unusual behavior and ask, "What is happening?" or "Why?"
Observation is heavily used in social sciences, behavioral studies and anthropology, as a way of studying a group without affecting their behavior. Whilst the experiment cannot be replicated or falsified, it still offers unique insights, and will advance human knowledge.
Case studies are often used as a pre-cursor to more rigorous methods, and avoid the problem of the experiment environment affecting the behavior of
an organism. Observational research methods are useful when ethics are a problem.
Conclusion
In an ideal world, experimental research methods would be used for every type of research, fulfilling all of the requirements of falsifiability and generalization.

How to Write a Scientific Paper
Judges will read your research paper. Your paper SHOULD have eight sections: Title page, Table of Contents, Summary, Introduction, Methodology, Discussion, Conclusions, Credits and References.
You start with a title. Use the same title for your paper that you used for your project. Center the title near the middle of the page. Towards the lower right corner, place your name, the name of your school and your grade level.
The table of contents is written after your paper is complete and after you have numbered all the pages.
An abstract is an overview. The first part of your paper is the part that you write last. Your abstract is a short section, approximately 250 words. It contains clear but brief summary statements. You summarize: (a) the problem or question(s) you are studying, (b) the action that you took in your investigation, (c) the results of your experiment(s), and (d) your most important conclusions based on your results. Display a copy on your project.
The introduction tells what you are going to do. This sets the scene for your report. The introduction explains what prompted your research and what you hoped to achieve. The first part of the introduction tells the reader your understanding of the subject when you started your project. Next tell how you became interested in your project. Then describe some information that you found when you studied your subject, for example: historical and scientific background, similar experiments done by others, and any contradictions or unanswered questions you may have found. Finish the section with statements that: (1) describe exactly what you want to prove or disprove, (2) tell why this proof should be done, (3) detail the information that you want to obtain from your project, and (4) tell how this information could be used. The time to write the initial version of the introduction is while you are planning and starting your project!
Methodology tells how you did your experiment. This section gives all
the details about how you conducted the experiment. Describe in detail how you derived your data and observations. It is so precise that another person could repeat your work just by following your instructions. List all materials that you used. Any apparatus you constructed should be photographed or drawn and discussed. Photographs, sketches and diagrams help to make your ideas clear.
Answer questions that apply to your project, such as: What and how was it measured? What variables did you collect data for? How did you run the control experiment? What subjects did you use? How or where were your supplies mixed, made or grown?
The discussion talks about your data. The discussion of your project is
the heart of the paper. It will usually contain several subsections. A good way to begin is to present all of your observations and data in both as – collected and processed forms. Discuss how and why you processed your data. Explain anything you assumed to process the data. Tables, charts and graphs are very helpful. Place all graphics in the paper near the paragraphs in which they are discussed. Clearly label and identify all columns, axes and data. Each item must have its own title.
A complete paper will include a discussion of possible errors. How did the data vary between repeated observations of similar events? How were your results affected by uncontrolled events? What are the sources of possible error? How large are these errors? What would you do differently if you were to repeat this project? What other experiments still need to be conducted?
The conclusion is a summary of your results. The conclusion restates briefly the findings and results detailed in your discussions. Do not mention new topics or speculations unless you referred to them in the discussion. Conclusions are based on your work and experiments. They do not come from news articles and textbooks. Make a comparison with theories, commonly held beliefs and/or expected results. Your conclusions and implications should flow smoothly and logically from your data. Be thorough. Let your readers know exactly what you did. Let them follow your train of thought.
Give credit where credit is due. The last section of your paper gives credit to other people for their work and assistance. First, a list of credits recognizes the aid given to you by people, business and institutions. Second, list the references you used. This is called a bibliography. This recognizes the information taken from the works and writings of other people. There are standard bibliography forms. See your English teacher.
A first-class look requires extra care. Carefully review your first draft. Check for correct spelling. Since you are very familiar with your project it is easy to leave out important details. Let an adult who is not familiar with your project read your paper. If they have trouble understanding your paper, maybe you left something out. Have your paper proofread a final time, then type
the final draft with double spaced lines. If you can't type, get help from someone who can.
