Describe Independent Groups Design Separate groups of participants are assigned to the various levels of the IV so that each individual participates in only one level (or condition/group) Link Between Internal Validity and Confound Variables Internal Validity A study that has eliminated alternative explanations has good internal validity When a study has good internal validity, we can conclude with some confidence that the IV is affecting the results and not some other unwanted variables When two variables are confounded, they are intertwined so you cannot determine which variable is operating in a given situation A variable that varies along with the IV so that its effects cannot be dissociated from the effects of the IV Aka third-variables, extraneous variables. A confound variable provides an alternative explanation for the results threat to internal validity Methods Used to Minimize Impact of Confound Variables

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
