Psychological research - Lab experiments - Data
This method mostly applies to psychological research to uncover the causal relationships between variables. This area makes use of scientific research to evaluate the relationship between variables. Experimental psychological methods determine if a change in one variable grounds a change in the additional variables in the experiment. Lab experiments are important since they allow the psychologists to manipulate variables and test hypothesis (Woodworth, 2009).
The experimental research process comprises of three major steps, namely formulating the hypothesis, designing a study and collecting data, analyzing the data collected to reach conclusions and sharing the findings. Psychological experiments are guided by various ethical guidelines especially where human beings are involved. The experiment's subjects need to be aware of the experiment process and consent to engage in the process.
Experiments differ with situations such as lab experiments, quasi experiments and field experiments. The type and nature of the project determine the type of research to be carried out by the psychologists.
[...] On a correlation base, I will evaluate the relationship between my personality traits and aggressive behaviour and then conduct a quasi-experiment on the same to evaluate hypothesis. Correlation and experimental theories play a great role in the development of psychological research theories. The type of project that a psychologists wish to evaluate determines the type of research to be conducted. If a project entails the relationship between the variables, correlation research is carried out 2008). References Li, J. (2008, June 9). Givology.

[...] The Walberg theoretical model of education productivity provides an example of the correlation psychological research methods. The theory was tested through fifth-eighth grade students. The relationship between the home environment, peers, media, and time spent on tasks, motivation, and the social environment. These variables were tested to identify their relationship with the education productivity model with each variable producing different result (Lomax, 1998). In the day-to-day life, various life aspects can apply the paradigms of correlation research and experimental research methods. [...]

[...] Psychologists have applied this research method in various studies in psychology. For instance in the study of conditional and unconditional responses to stimulus, Ivan Pavlov conducted a research with dogs and food. In his experiment, Pavlov provided the dog in the lab with food and rang a bell at the same time to measure the salivation. After several repeats of presenting the dog with food and ringing a bell, he withdrew the bowl of food and only rang the bell. [...]
