13. facebook Australian Statistics Competition WallPhotosHirzi Putra-Laksana and Sagar BadveLogout Wall InfoPhotos Information Info Photos Conclusion: Our original hypothesis was that ”As the number of Facebook friends you have increases, your academic performance decreases in quality.” We have in a way approved this hypothesis but in another way disproved it. While it seems that the No Facebook group has better marks and the 700+ Facebook friends group has lower marks, we can see from the previous given analyses and examples that there is no direct downward trend in the marks decreasing as the number of Facebook friends you have increase. Evaluation: Because students we surveyed from our school was academically gifted (we go to a selective academic school), there would obviously be a high standard of grades and therefore higher marks. This proved a less diverse population to survey. Author Information Name: Hirzi Putra-Laksana and Sagar Badve Year: Year 9 School: Perth Modern School Wall Friends
