Science is a system we have developed for the acquisition of knowledge about the sensory world. That world includes people, institutions, culture, technology; in short, anything you can see, hear, feel, touch, or smell. Scientists do research to try and find answers to questions, usually in an effort to solve problems, but sometimes simply for its own sake. They are usually looking for cause and effect relationships between the things in that world.
Research Methods
The interpretations which result from research (data, theories, program proposals, etc.) produce
findings not facts and what you make of that product, its value to you, depends on the degree to
which the perspective and processes used by the researcher are compatible with your own.
Furthermore, although their methods are generally more explicit and formalized, researchers really
don't have any additional intellectual tools available to them than you do. Those doing hard science
research (chemistry, biology, medicine, etc.) simply have access to expensive instruments or a staff
of assistants. Those doing soft research (sociology, psychology, anthropology, etc.) have the money
to send out questionnaires or teams of interviewers. But they both find out about their part of the
world by observing it or by asking others about it and then analyzing the raw data.
Finding A Topic
Getting a topic idea is relatively easy for the professionals. They have substantial experience, they
know what they’re dealing with, and they know how to convert the topic into one of sufficient
specificity and focus so that their research makes a contribution to knowledge and is "doable"
within the parameters of time, resources and opportunity. The key to doing the latter is
generally specificity in reviewing previous and existing research or intervention projects. That is,
simply reading texts or summaries or popularized accounts of those projects is not sufficient. One
needs to become as familiar as possible with those projects and that usually means examining the
complete descriptions published in journals, presented at conferences, or critiqued in a variety of
professional forums.
Research Terms
Here are a few terms you may come across as you do your own research into the reports and
documents which result from the research of scientists.
Paradigms
Data
Cause
Theories and Models
Validity
Reliability
Research Design
Representative Sample
Demand Characteristics
Experimenter, Interviewer, or Observer Bias
Quantitative Methods
Population
Sample
Parameter
Statistic
Research methods are the processes researchers use to obtain and analyze data. They are the
processes researchers use in order to increase their understanding of a part of their world. These
processes have been developed by the scientific community over time and have become an
accepted part of the culture in which we are socialized and educated. But no matter how hard the
scientific community works at achieving objectivity, research is still done by people, so when you
look at the results of research (typically in a publication or other form of report) you should
remember that we learn as much about the researcher as what they researched.
A paradigm is a framework implicit in any research. There are four major paradigms which affect
research:
Unadulturated information about phenomena; a pile of questionnaires is a set of data.
A factor in the relationship between phenomena; in western culture, cause must meet these criteria:
Theories and Models explain relationships between phenomena. Predictions or hypotheses can be
derived from them concerning relationships which can be tested in the real world. If the
hypothesized relationships are found, the theory or model is supported. Research focusing on the
testing of hypothesized relationships is called hypothesis-testing research. In an analogous way,
predictions can be derived from programs or policies and tested empirically. This type of research
is often called evaluation research, social impact analysis, market research, needs assessment
research, and so forth.
A primary requirement of research is that it have five kinds of validity (truth).
The extent to which the data is replicable both within and across research contexts.
The structure of the research; how the variables were assessed, manipulated, or controlled to
establish relationships.
A sample in which the subjects are randomly selected so that each member of the population being
studied has an equal opportunity of being selected; selection of one subject does not alter the
opportunity of others in the population being selected
Characteristic of bad research; the information communicated by the research produces the desired
or expected behavior--you get what you expect.
A tendency to obtain differences in behavior and/or observation or measurement of that behavior
between conditions consistent with the experimenter's expectations.
Applied mathematics as used to help describe and draw inferences from research data.
Any class of phenomena defined in terms of unique and observable/measurable characteristics--
usually the people the researcher is interested in understanding.
Some subset of a population--the people the researcher actually studies.
A mathematical characteristic of a population.
A mathematical characteristic of a sample.
