Your name:
Which class are you in? 1:20pm 5:15pm
Your e-mail address (so I can send you back your graded assignment):
Choose from the following hypotheses:
Infants will suck harder on a pacifier when they hear their mother's voice as compared to that of another woman. People are more likely to go along with a group if the group is unanimous. Antidepressant medication is effective at treating depression. Our judgments are more influenced by how vivid an example we are given than by statistical evidence.
Description of your experimental design (10 points)
Rubric for grading the description portion of this assignment.
Independent Variable
Dependent Variable
Number of Participants
Random Assignment
Confounding Variables
2
Describes an appropriate IV; describes appropriate experimental & control conditions
Describes an appropriate DV with an operational definition
Sufficient number of participants; demonstrates an understanding of the importance of numbers
Appropriate use of random assignment; demonstrates an understanding of the value of random assignment
No confounding variables present
1
Describes an appropriate IV; describes inappropriate experimental & control conditions
Describes an appropriate DV without an operational definition
Just mentions “groups” without a number specified; does not demonstrate an understanding of the importance of numbers
Just mentions “random” without context; confuses random assignment with random sampling
Confounding variables present; attempts to control for confounding variables
0
Describes an inappropriate IV
Describes an inappropriate DV
1 or few participants per condition; does not demonstrate an understanding of the importance of numbers
No mention of random assignment
No mention of an attempt to control for confounding variables
Independent variable (5 points)
These are the groups you are comparing. This variable represents the "cause" half of the hypothesis. You may have more than one experimental condition and more than one control condition. Most will have only one of each. Experimental condition Control condition
These are the groups you are comparing. This variable represents the "cause" half of the hypothesis.
You may have more than one experimental condition and more than one control condition. Most will have only one of each.
Dependent variable (5 points)
This is what you are comparing those groups on. This variable represents the "effect" half of the hypothesis. You may have more than one dependent variable. Most will have only one. Dependent Variable
This is what you are comparing those groups on. This variable represents the "effect" half of the hypothesis.
You may have more than one dependent variable. Most will have only one.
