Instruction of Project
For this project, we were asked to do an individual project. We need to take a secondary data from the internet and do testing from the data. The tests that are compulsory are hypothesis testing, correlation, regression and the other one is optional and I choose chi-square test one way contingency. We first need to submit our project proposal, after approved only then proceed to do the analysis. The analysis must be done in Rstudio. Follow up by report, video presentation and this e-portfolio.
Introduction of my Project
The data that is used in this project is from Royal Malaysia Police. The data is about general road accident that has happened in Malaysia for the past years. The purpose of Royal Malaysia Police collecting this data is for annual report on road accident statistics. The data consist of year, registered vehicle, population, road crashes, road deaths, serious injury, slight injury, index per 10000 vehicles, index per 10000 population and index per billion vkt. The year is the only different type of data which is nominal and the others are categorize as ratio type of data. The data consist of year from 1997 to 2016.
The data that is used in this study is year, registered vehicles, road crashes and road deaths. The purpose of this study is to see whether the mean of death caused by road accidents is equal to 6000, is there any relationship between registered vehicle and road crashes, to see the impact of the number of car crash and the number road death and to see if the probability of having road death is equal in the 20 years of study.

Conclusion of Project
In conclusion, the objectives for the study were successfully accomplished through several test. I can conclude that even the number of registered car will affect the number of car crash, it does not mean we will have increasingly the number of car crash as the number of registered vehicle increase. We can have more people buying their desired car and still reduce the number of car crash by being a rational road user. We need to apply what we learn from our driving school such as check the car condition before use it, check the side mirror and most importantly wear the seatbelt. In addition, we must avoid reckless driving such as drive while being drunk or even drive at the emergency lane. Even you follow the procedure but being reckless while driving might also cause car accidents. Before I close this paraghraph, I want to remind that remember your loved ones before you begin your journey with your car.
My Reflection
My reflection regarding this project is that I learn how to code new thing in Rstudio. Before this, I did Project 1 of this subject (SECI2143 - PROBABILITY & STATISTICAL DATA ANALYSIS) where as in a group we need to do the coding in Rstudio for analysis. But this time the coding is completely different and new, but now it is easier to me as I already have the basic from project 1. Also, new thing I learn from this project is that even the project is given as individual, it does not give as much pressure as I thought. The only pressure I get is from time, because since this project is during COVID-19 pandemic, I get a lot of works like assignments and projects from other subjects, so I really need to catch the time. Even that, I still manage to complete this project and manage my time properly. Aside from that, I also learned to interpret secondary data and make hypothesis on my own which is quite amusing to me. I think that is all I have to say about my reflection on this project 2. Thank you for reading and have a nice day ahead.
