1. What is the appropriate factorial notation for the design of this study (e.g., 3x3x2 Mixed design)?

1. State the 3 alternative hypothesis for the study in terms of the effects or the IV's (Factors) on the DV:

Hypothesis 1:

Hypothesis 2:

Hypothesis 3:

1. Complete the following means table including the marginal means:

1. Complete the following based on your descriptives table from the SPSS output:

1. How many participants are in the study?
2. How many scores are in each factorial condition (cell)?
3. Which factorial condition had the highest mean error rates?
4. Which factorial condition had the most variability in error rates?

DV =Error rate on grammatical reasoning test (%)	Independent Variable: Lighting	Marginal means for noise conditions
Dynamic lighting	Static lighting
Independent Variable: Noise	Low intelligibility
High intelligibility
Marginal means for lighting conditions

1. For each effect, provide a sentence that states the significance of the effect on grammatical error rates and report the F statistic in APA format including effect size (partial eta square).

1. Main effect of lighting:

1. Main effect of noise:

1. Interaction effect:

Analysis Interpretation:

Which effect (lighting, noise, interaction) explains the greatest amount of variability in error rates? What % of the overall variability in scores does this effect explain?

Paste the plot from your JASP output and interpret any significant main effects and interaction(s)in a brief paragraph summarizing the results of the study:
