A hypothesis is a verifiable statement about truth. An experiment is a test of whether a hypothesis is true, and a theory is a condensation of all the experiments that support the truthfulness of a hypothesis. A theory always has some reproducible, well-designed experiment in support of it, and some theories have hundreds of thousands of observations supporting them.
This all sounds grand and ideal, but neither the formal scientific method nor any of the several other scientific methods proposed by philosophers of science are how science is actually done. Modern science has amassed a virtually infinite body of knowledge. The chance that any scientist is really working on something new is small. There is no need for hypotheses, and the theory of genetics is already abundantly supported.
What this young scientist is taught in exquisite detail, especially at higher levels of education, is appropriate experimental design. A particular mistake often made in medicine and biology can be illustrated as follows: An experimenter mashes up the leaves of the herb in ethyl alcohol and filters the extract. This outcome sounds plausible: Something in the herb cured the rash.
Consider, however, this statement: Even if the person observes this several days in a row, no cause-and-effect relationship exists between the alarm clock making a noise and the occurrence of dawn. One event followed by another event does not mean that the second event was caused by the first event. In the earlier example, it is not known if the ethyl alcohol cured the rash or if the rash would have cured itself in two days without intervention. These types of errors can be subtle.
For example, a study to find out if a certain drug had a curative effect on bedsores in hospitalized persons can be clouded by the fact that one-third of the persons with bedsores will be cured simply by signing up for the research and receiving no treatment whatsoever. Bedsores are caused by a lower standard of care and when persons cannot move around in bed. The only acceptable experiment is the double-blind clinical study. In this type of study, the participant population must be large, and treatment and controls must be masked blinded so that neither the physician nor the participant knows who is receiving treatment versus control.
When thinking about researching science versus researching something like hair products, it is important to think about the process or procedures that you are taking. What does a scientist do in a well planned and controlled experiment?
When creating and running an experiment it is important that the scientific and research methods are followed. The first step is to form a research question that you can test.
The second step it to The results of an experiment is call what in the scientific model? When using the scientific model, the results of an experiment--which will have tested an hypothesis and have been built upon observations carefully recorded--are called the data. The data are the What are the five steps of the scientific method?
The five steps of the scientific method are as follows: State the problem example: What gets hotter in the sun: What makes science different from other epistemologies? Science is different from other epistemologies in that it is founded, ultimately, on empirical observation. Where philosophy may rely on logic, and the humanities on texts, sciencists draw their What do you think makes science scientific? Science is the process of explaining observable phenomenon through testable methods.
What makes science "scientific" is the scientific method which is a process that outlines how a question is What is the reasoning for collecting data and interpreting the results when doing a science When conducting scientific inquiry, there has to be a rationale behind the investigation.
