Welcome to the survey on graphical inference

This web site is designed to conduct a survey on graphical inference which will help us understand the power of graphical inference procedure in the field of statistical research.

This research is being conducted by Mahbubul Majumder under the supervision of Dr. Cook and Dr. Hofmann, Department of Statistics, Iowa State University, funded in parts by NSF grant DMS 1007697. If you have any questions please contact Mahbubul by email to mahbub72@gmail.com.
The following examples illustrate how you may respond to the survey questions.

Example 1: In which of these plots do the two groups have
the most vertical difference?

    Your choice: Plot 2 (the second one)
    Reasoning: Points most spread apart
    How certain are you on a scale of 1 to 5
            (1= most certain, 5= least certain): 1
    Your Nick Name: Mahbub

Example 2: In which of these plots is the green line the
steepest, and the spread of the green points
relatively small?

    Your choice: : Plot 3 (the third one)
    Reasoning: Green line has steep positive slope, points close together
    How certain are you on a scale of 1 to 5
            (1= most certain, 5= least certain): 1
    Your Nick Name: Jane

Example 3: In which of these plots do the two groups have
the most vertical difference?

    Your choice: : Plot 4 and 3 (order matters)
    Reasoning: Points most spread, except for one point in plot 3
    How certain are you on a scale of 1 to 5
            (1= most certain, 5= least certain): 1
    Your Nick Name: Jane
