  4. Reporting Statistics • 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 = ____’
