1. TuTh – 4:00-5:15 Psych 241 – Methods Lab section 03

2. Reporting Statistics

4. Three questions to answer when you report results: What type of test did you use, and what did you use it for? What were the differences and were they significant? What does your result mean?

5. Reporting Statistics The key statistics to report: Mean differences: These are the numbers that show which direction the differences are in, and they can help us get an idea of how large of a difference there is. Statistical significance: Are these differences significant? Report what statistic you used and what the value is. Report the degrees of freedom. Reports the significance value. Significance value should be reported as ‘=‘ UNLESS the result says ‘.000’ in which case we say that the result is ‘<‘ (less than).001.

6. Example Pens down! ‘There was a significant (not a significant) difference in the scores for IV level 1 (M=___, SD=___) and IV level 2 (M=___, SD=___) conditions; t(__)=___, p = ____’
