Strengths And Disadvantages Of Experimental Research

Research can be used in many methods, for example: questionnaires, television, leaflets, books etc. it allows us to keep up to date on the new findings or discoveries e.g. a new type of cancer or a new vaccination. Research is the investigation into

According to Depoy and Gittin, research is a way individuals think about problems in systematic way. Research is generally described as description, exploration, analysis, prediction and problem solving. There are different types of research and these researches are called the experiments, quasi-experiments and non-experiments. The purpose of research is to provide the insight to practice, it also enhance individuals understanding as well as developing new approaches with different topics, get to test your research for effectiveness. Understanding research is important because it helps to build individuals knowledge bases and informs decision making in practice. Research also enable us to make sure that our practice are up to date with relevant information.

Experimentation - An experimental photography technique can be defined as anything that we use to change a photography in a way that differs from just taking a photograph. It is a mean of depicting a visual image that does not have an

| -They produce data on very specific, narrow topic i.e. the relationship between two variables-Experimenting on human beings in care situations raises difficult ethical issues (Moonie, Stretch, et al, 2003).-Participants usually know that they are in an experiment which may affect the behaviour they produce-It may be time consuming(Stanley, Boswell, et al, 2009).

Whether research is experimental or developmental, there are no guarantees of perfect study processes or results, since both random and systematic errors are expected. Errors and uncertainties of a study’s outcomes surface almost every time. Faulty, aged or incorrectly calibrated instruments, during an experiment, can lead to important alterations of results. Distracting environments definitely influence the outcome. Finally, the human parameter in the sense of having ability to properly operate instruments and correctly interpret measurements definitely consist another factor of imperfect research (Bell 7-9).

It helps clarify relationsips between variables that cannot be examined by other methods and allows prediction

Experimental research concentrates on how and why something happens. It is the evaluation of how an independent variable (a manipulated factor) affects a dependent variable (an observed factor). The outcome can be affected by a number of elements; obtaining random and representative samples of the study population, experimenter bias and extraneous variables.

The study was experimental because: 1) the researchers did manipulate the independent variables, and 2) Participants were randomly assigned to one of two groups.

I am on the affirmative side and I think that Human experimentation is important because scientists and doctors can find new and more effective treatments for diseases. Human experimentation is when human beings are used as test subjects to research scientific and medical resources. Scientists can start with hypotheses and test them on animals,but without human testing they will never know if the end results will actually make real human patients feel better. Experiments on people have contributed in great measure to medical progress; infant mortality has decreased by more than 75%,and many human diseases that were once fatal or widespread have become curable or have disappeared. Human experimentation is important for the good of all people.

Experimental design research tends to use math and statistics to try to prove or disprove a hypothesis. Within an experimental design most of the research is controlled and leaves little room for error. One advantage of experimental design is that it is hard to disprove the results. However, a disadvantage is that because the conditions are controlled that makes the results too perfect. If the same experiment was conducted in an uncontrolled setting, such as the real world, the results would vary.

"Correlation is a measure of association that tests whether a relationship exists between two variables. It indicates both the strength of the association and its direction (direct or inverse). The Pearson product-moment correlation coefficient, written as r, can describe a linear relationship between two variables" Correlation (n.d). As a human service professional and completing research there are advantages and disadvantages to correlational research methods, such as using correlational research it allows us to collect data and determine the strength and direction of what it is we

Quantitative Research- a research based on experimental data, a survey that proves the actuality of the theory.

Observational research is type of correlational (i.e., nonexperimental) research in which a researcher observes ongoing behavior. There are a variety of types of observational research, each of which has both strengths and weaknesses. These types are organized below by the extent to which an experimenter intrudes upon or controls the environment.

In Psychology 101 we learned that research methods are used in order to understand our mental and behavioral processes by making observations in a systematic way, following strict rules of evidence and thinking critically about that evidence. This scientific research is based on theories (tentative explanations of observations in science), hypotheses (predictions based on a theory) and replication (testing a hypothesis in more than one study). Some of the different research methods are firstly, descriptive studies. Descriptive studies are studies that use survey methods, naturalistic observation and clinical methods. Another research method is correlational studies. Correlational studies are studies that help one to determine if a relationship exists between two or more variables and if so it tells one how strongly those two variables relate to one another. With in correlational studies one can have positive correlation (as one variable increases or decreases so does the other), negative correlation (variables go in opposite directions) or zero correlation (no relationship between the variables). Another research method is formal experiments. Formal experiments are studies that allow us to draw conclusions about how one variable may cause or have an effect on another variable. With in formal experiments there are four elements, which are the independent variable (variable that is manipulated or controlled), the dependent variable (variable that is measured), the experimental
