StatLab 8a: 2-Factor Anova for independent groups A researcher wanted to investigate if there is any effect of level of motivation and/or task difficulty on task performance. He decided to use three types of incentives to manipulate participants’ motivation (i.e., three levels of motivation = low, medium and high) and he prepare two tasks that differ in levels of difficulty (easy and difficult). Participants were randomly assigned to one out of six experimental conditions and their performance on the task was measured. The obtained data are listed below. Is there any evidence that motivation and/or task difficulty produced a significant effect on task performance? Motivation: LOW Motivation: MEDIUM Motivation: HIGH Task: EASY 3,1,1,6,4 2,5,9,7,7 9,9,13,6,8 Task: DIFFICULT 0,2,0,0,3 3,8,3,3,3 0,0,0,5,0 1.

    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.
