  6. Exam 3 – next class – Thursday (11/8/11) Study guide is posted online now Bring 2 calculators (remember only simple calculators,we can’t use calculators with programming functions) Bring 2 pencils (with good erasers) Bring ID Remember, in-class activity on Nov 10th Remember to bring a laptop to class on Thursday (if you have one)

A one page report of your design (includes all of the information from the writing assignment) • Describe your experiment: what is your question / what is your prediction? • State your Independent Variable (IV), how many levels there are, and the operational definition • State your Dependent Variable (DV), and operational definition • How many participants did you measure, and how did you recruit (sample) them • Was this a between or within participant design (why?) • 2. Gather the data • Try to get at least 10 people (or data points) per level • If you are working with other students in the class you should have 10 data points per level for each member of your group • 3. Input data into Excel (hand in data) • 4. Complete ANOVA analysis hand in ANOVA table • 5. Statement of results (see next slide for example) and include • a graph of your means (just like we did in the homework)

  9. One way analysis of varianceVariability is divided Remember, one-way = one IV Number of cookies sold None Bike Hawaii trip Incentives Total variability Between group variability (only one factor) Within group variability (error variance) This will be our numerator – like difference between means This will be our denominator – like within group variabilityRemember, error variance = random error

  10. Two-way analysis of varianceVariance is divided further College Number of cookies sold Elementary Remember, two-way = two IV None Bike Hawaii trip Total variability Between group variability Within group variability Remember, factor = independent variable Remember, within group variability = error variability= random error Factor A Variability Factor B Variability Interaction Variability

  11. Writing Assignment Factor BB1B2 DependentVariable A1 A2 Factor A Generate an 3 examples Independent Variable 1? Independent Variable 2? ? ? Dependent Variable? Main effect of A ? Main effect of B ? Interaction ?
