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 mahbub@iastate.edu. The following examples illustrate how you may respond to the survey questions.

Example 1: Which of these plots is most different from
the others?

Your choice: Plot 2 (the second one)
Reasoning: Outliers
How certain are you on a scale of 1 to 5
(1= most certain, 5= least certain):
1

Example 2: Which of these plots is most different from
the others?

Your choice: : Plot 3 (the third one)
Reasoning:  Blue and red boxes are vertically displaced
How certain are you on a scale of 1 to 5
(1= most certain, 5= least certain): 1

Example 3: Which of these plots is most different from
the others?

Your choice: : Plot 2 (The second one)
Reasoning: Trend
How certain are you on a scale of 1 to 5
(1= most certain, 5= least certain): 1
