Project 2 Reflection
In this project, we exposed to the practical way of carrying out various statistical tests on our
favorite topic and applying the knowledge of inferential statistics. We also get to learn basics of
R programming language that we deemed important in our future career. Our main topic concerns with marathon running. The objective of our project is to test those fallacy claims(such as "the more you run, the faster you will become" and "East Africans are born to be good runners") which are statistically unsupported.
From our calculations and data analyses in 2-sample hypothesis testing, we have discovered that
the recent invention of the Nike Vaporfly shoes that consist of carbon-plate had helped most elite
runners in marathon running over the years.
From correlation and regression test, we discovered that miles ran per week do indeed have considerable impact on overall
marathon performances. However, we believed there are other factors that contributed to faster
marathon running times and it will be highly individual, meaning not a single kind of medicine
could be suitable to all the patients.
In chi-square test of independence, the myth over the
decades that running is being dominated by East African runner was proven wrong in our
project. However, the limitations of this project are small sample size and chosen value of alpha.
Therefore, further research are required to test those claims.
Last but not least, I would like to express my appreciation towards my groupmates Afifa Jumana and Henry Meshack Okinyi Odongo and my lecturer Dr. Azurah binti Samah. The process of the project preparation did not come easy but in the end it was successful with the cooperation and guidance respectively from my fellow groupmates and lecturer. We had referred to various websites, went through trials and errors before we could arrived the calculations in this projects.
