Q: write a discussion on the external and internal reliability of the study of Canli et.al (2000) ?
Answers
Answer:
The study by Canli et al. (2000) investigated the neural basis of emotional processing using functional magnetic resonance imaging (fMRI). The reliability of a study refers to the consistency and stability of its results and conclusions and can be divided into two categories: external and internal reliability.
External reliability refers to the consistency of the results across different studies and research groups. In the case of Canli et al. (2000), the external reliability of the study can be evaluated by examining whether similar results have been found in subsequent studies that have used similar methods to investigate the neural basis of emotional processing. If multiple studies have found consistent results, this would suggest that the study by Canli et al. (2000) has good external reliability.
Internal reliability refers to the consistency of the results within the study itself. In the case of Canli et al. (2000), internal reliability can be evaluated by examining factors such as the quality of the data collected, the use of appropriate statistical methods, and the consistency of the results across different participants or conditions. If the results are consistent within the study, this would suggest that the study has good internal reliability.
In conclusion, both external and internal reliability are important factors to consider when evaluating the validity of a study. While the study by Canli et al. (2000) is well-designed and has produced important findings, it is important to continue to examine the reliability of the results through additional studies and research methods.
