Strengths And Disadvantages Of Experimental Research

(a) Experimental Research is a form of quantitative research where the experimenter manipulates the conditions in one group to see if certain activities or materials will change the outcome.

The strengths of experimental research are that the researcher can have control over variables and it can be used in many fields of research. Also, there are clear conclusions and researcher can tailor the experiment to his or her needs making it easy to determine the causes and effects.

The weaknesses of experimental research are; there can be human error, the researcher's personal bias can intrude and the sample may not be representative. Other weakness includes producing an artificial situation and results as well as results may only apply to one situation and may be difficult to replicate. In addition, groups may not be comparable because human response can be difficult to measure since participants may be influenced by their environment; it can take a long time and lots of money to complete research.

(b) Correlation is a quantitative method that looks at the relationship between two variables.

The strengths of correlation research are, it doesn't have to manipulate behavior, allows for prediction and allows the researcher to examine issues that cannot be studied ethically or practically in experiments. It is also a good starting point for deeper research and for investigating whether two or more variables are related.
