Probability & Statistical Data Analysis
During this project, I was assigned to do the optional analysis where I could choose between three test which are goodness-of-fit test, Chi Square test of independence test and lastly the ANOVA test. Before choosing the test, I try to do some research for each test to compare what is the best test for the dataset that my group has chosen which was the ‘2019 World Happiness Report’ by exploring the internet and also by rewatching the lecture videos in E-Learning. By doing these researches, I was able to get a better and deeper understanding between the three tests. At first, I have chosen to do the Chi Square Test of Independence however after making some calculations, I discovered that my calculations looked strange. With that, I tried contacting my groupmates to help and assist me which helped me in developing communication and teamwork skills. After deciding to use ANOVA test, I did more research on ways to do the calculations in Rstudio and also on generating the graph.
By conducting this project, I not only was able to get a better grasp of understanding in the various tests that has been taught throughout the semester but I also managed to gain different skills such as using the Rstudio and Excel where I learned the ways to utilize these two softwares to help making the process of analysing and plotting graph easier by watching Youtube videos and reading explanations and examples in different sites. I also was able to enhancie my communication skills and others which is very useful for me in the near future. By learning the importance of doing all the tests such as the hypothesis testing, ANOVA test, correlation test and regression test, I will apply this new learned skill and knowledge in my future studies and career.
