Reporter For this in-class activity, each group needs to first identify a recorder/reporter for their group. This reporter will report back to the full class and share. Reporter: ?

Problem (the reason for the need for the study)

Purpose (based on the problem, what is the purpose of this proposed study?)

Causal Variables of Interest IV: Must include at least one of the following: Independent variable = … Quasi-independent variable = … DV: Identify a single dependent variable: Dependent variable = … Measurement – How?

Causal Research Question

Causal Statistical Hypothesis(es)

Causal Study Design Notation Observations or measures: O=measure (DV) Treatment: X=treatment (IV) Group Notations: R=Random Assignment: N=Non-random Assignment; C=Cutoff Score Can use rows to represent different treatment groups. Time can be represented horizontally. O.K. to add subscripts when needed. O O X X C C O O R R N N

Factorial Design Basics Consider additional categorical variable for analysis. To examine for interactions To eliminate as confounding variable Gender is one possible categorical variable to consider in addition to treatment groupings. Example in textbook uses the following factors, each with two levels (2 X2 Factorial Design): “In-class” vs. “Pull-out” “1 hr/wk” vs “4 hr/wk”
