In a cognitive psychology experiment, the researcher is interested in whether encoding condition has a
significant effect on memory for a set of drawings. In encoding condition A, subjects are asked to name
the object in each drawing; in encoding condition B, subjects are asked to name the color of each
drawing. Then all subjects are tested on their memory of the drawings. Each recruited subject is
randomly assigned to either encoding condition A or encoding condition B.
Based on memory theories, the researcher hypothesized that condition A (object naming) would lead to
significantly better memory compared to condition B (color naming), and she sets the significance level
at α = .05 for a one-tailed test.
Hint: You may remember a similar scenario in the previous assignment, but with a crucial difference. In
the previous assignment, each subject is tested in BOTH condition A and condition B, while each subject
here is tested in only ONE condition (either A or B).
a. What is the dependent (outcome) variable? What is the independent (grouping) variable?
b. Create the null and alternative hypotheses for this study, using both words and symbol notation.
