Conclusions

(f) Summarize your conclusions as if to the readers of a psychology journal, including whether the observed difference is considered statistically significant (with justification), whether you are drawing a cause and effect conclusion, and to what population (justify these decisions based on how the data were collected and the significance of the results), and any potential problems with the study and how it could be improved if you were to conduct it in the future.
