There are advantages and disadvantages of the experimental method in psychology. Even if the variables are controlled, the outcome may ensure internal validity, but do so at the expense of external validity. This research often limits the sudden and unpredictable outcomes of the research. The data's tendency should be maintained enough to get fixed and meaningful interpretations to detect any type of formula. A hypothetical study has been described below to show how the experimental method is used in psychology research. Being able to manipulate variables reduces that objectivity. Many Variations Can Be Utilized Obtaining a significant correlation between two variables never guarantee the possibility of the existence of the other one.

A hypothesis could predict a negative correlation where the less friends a person has, the more they are likely they are to have a depressive disorder. Correlational research is a subtype of descriptive research. Field experiments are done in the everyday (i.e. Dependent Variable (DV)- The DV is the variable that is being observed and measured. Disadvantages include the low ecological validity of lab experiments and demand characteristics participants may present. Some examples of correlation include: a positive correlation between smoking and lung cancer; a negative correlation between the summer season and the sale of hot cocoa; and a possible correlation between height and shoe size.

This allows researchers to have a greater control of the extraneous variables which may exist as well, limiting the unpredictability of nature as each variable is being carefully studied. Sometimes, the control of variables could be done in order to extract the desired or manipulated results of the data. This research demands too much time Each variable gets tested after making that isolated. For it to be done properly, experimental research must isolate each variable and conduct testing on it. Every single new medicine or drug is testing using this research design. Largely Subject To Human Errors It provides researchers with a high level of control. While there are a number of different research techniques available, the experimental method is one that allows researchers to look at cause-and-effect relationships.

Correlational studies are used to assess if a relationship exists between two variables. This helps to promote the validity of a concept for products, ideas, and theories. The DV is the variable that is being observed and measured. The experimental research may be characterized as a study, which is done by using various scientific research designs. The experimental method gives researchers a high level of control since they choose the IVs and DVs, how to measure them, and the procedure of the study.
