Where to look for research paper ideas? How to Write A Unique Research Paper The best thing about writing a unique research paper is that you become a student of a certain topic, particularly if you never researched the topic before. It is important that you research the topic thoroughly before writing the first draft because you want to be well-versed in the subject and this helps you appear like an expert when writing the paper. When you start the paper you should start with the research you gathered then formulate a thesis statement that will guide the rest of the research paper.

Overview[ edit ] In the scientific methodan experiment is an empirical procedure that arbitrates competing models or hypotheses. However, an experiment may also aim to answer a "what-if" question, without a specific expectation about what the experiment reveals, or to confirm prior results.

If an experiment is carefully conducted, the results usually either support or disprove the hypothesis. According to some philosophies of sciencean experiment can never "prove" a hypothesis, it can only add support.

On the other hand, an experiment that provides a counterexample can disprove a theory or hypothesis, but a theory can always be salvaged by appropriate ad hoc modifications at the expense of simplicity.

An experiment must also control the possible confounding factors —any factors that would mar the accuracy or repeatability of the experiment or the ability to interpret the results. In engineering and the physical sciences, experiments are a primary component of the scientific method. They are used to test theories and hypotheses about how physical processes work under particular conditions e.

Typically, experiments in these fields focus on replication of identical procedures in hopes of producing identical results in each replication. Random assignment is uncommon. In medicine and the social sciencesthe prevalence of experimental research varies widely across disciplines.

When used, however, experiments typically follow the form of the clinical trialwhere experimental units usually individual human beings are randomly assigned to a treatment or control condition where one or more outcomes are assessed.

There are various differences in experimental practice in each of the branches of science. For example, agricultural research frequently uses randomized experiments e. History of experiments One of the first methodical approaches to experiments in the modern sense is visible in the works of the Arab mathematician and scholar Ibn al-Haytham.

He conducted his experiments in the field of optics - going back to optical and mathematical problems in the works of Ptolemy - by controlling his experiments due to factors such as self-criticality, reliance on visible Sample research paper in physics of the experiments as well as a criticality in terms of earlier results.

We should distinguish the properties of particulars, and gather by induction what pertains to the eye when vision takes place and what is found in the manner of sensation to be uniform, unchanging, manifest and not subject to doubt. After which we should ascend in our inquiry and reasonings, gradually and orderly, criticizing premisses and exercising caution in regard to conclusions — our aim in all that we make subject to inspection and review being to employ justice, not to follow prejudice, and to take care in all that we judge and criticize that we seek the truth and not to be swayed by opinion.

We may in this way eventually come to the truth that gratifies the heart and gradually and carefully reach the end at which certainty appears; while through criticism and caution we may seize the truth that dispels disagreement and resolves doubtful matters.

For all that, we are not free from that human turbidity which is in the nature of man; but we must do our best with what we possess of human power. From God we derive support in all things. Furthermore, a critical view on the results and outcomes of earlier scholars is necessary: He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency.

In this process of critical consideration, the man himself should not forget that he tends to subjective opinions - through "prejudices" and "leniency" - and thus has to be critical about his own way of building hypotheses.

Francis Bacon —an English philosopher and scientist active in the 17th century, became an influential supporter of experimental science in the English renaissance. He disagreed with the method of answering scientific questions by deduction - similar to Ibn al-Haytham - and described it as follows: Notably, he first ordered the scientific method as we understand it today.

There remains simple experience; which, if taken as it comes, is called accident, if sought for, experiment. The true method of experience first lights the candle [hypothesis], and then by means of the candle shows the way [arranges and delimits the experiment]; commencing as it does with experience duly ordered and digested, not bungling or erratic, and from it deducing axioms [theories], and from established axioms again new experiments.

For example, Galileo Galilei accurately measured time and experimented to make accurate measurements and conclusions about the speed of a falling body. Antoine Lavoisiera French chemist, used experiment to describe new areas, such as combustion and biochemistry and to develop the theory of conservation of mass matter.

A considerable amount of progress on the design and analysis of experiments occurred in the early 20th century, with contributions from statisticians such as Ronald FisherJerzy NeymanOscar KempthorneGertrude Mary Coxand William Gemmell Cochranamong others.

Types of experiment[ edit ] Experiments might be categorized according to a number of dimensions, depending upon professional norms and standards in different fields of study. In some disciplines e. The independent variable is manipulated by the experimenter, and the dependent variable is measured.

The signifying characteristic of a true experiment is that it randomly allocates the subjects to neutralize experimenter bias, and ensures, over a large number of iterations of the experiment, that it controls for all confounding factors.

Scientific control and Design of experiments A controlled experiment often compares the results obtained from experimental samples against control samples, which are practically identical to the experimental sample except for the one aspect whose effect is being tested the independent variable.

A good example would be a drug trial. The sample or group receiving the drug would be the experimental group treatment group ; and the one receiving the placebo or regular treatment would be the control one.

In many laboratory experiments it is good practice to have several replicate samples for the test being performed and have both a positive control and a negative control.Consumer Satisfaction and Service Quality Analysis of ACI Power Tiller Bangladesh is a South Asian country with the record of highest population density (% population growth per annum) where 77% people live in rural areas.
