Post a two (2) to three (3) paragraph discussion where you define the difference between the “validity” and “reliability” of an investigation. Then identify the factors that impact the validity and reliability of psychological research. Finally, explain how a psychologist can increase the validity and reliability of research.
Be sure to back up your arguments with this week’s assigned readings and cite sources using APA (Seventh Edition) formatting and style. Your post should be thoughtful and promote critical discussion with your peers and the class instructor.
