In this project, I study the secondary data obtained from the website https://www.kaggle.com/spscientist/students-performance-in-exams. As this project is a group project, I discuss what variable to assign to a suitable test: Hypothesis test, Correlation test, Regression test and Chi Square test. We divide the tests among ourselves. As this project is a group project, the tests are divided among my group. One person will be responsible on a test. I am responsible to complete a Chi Square test to test the relationship between the lunch and the students' performances.
When completing the project, I take quite a long time to get familiar with the environment of the RStudio so that I can interpret the result of the Chi Square test as I am still new to RStudio. I learn to code to conduct the Chi Square test in RStudio by searching Google and watch demo videos on YouTube. After the report is completed, I present the result by filming a presentation video.
Throughout this project 2, I have learned how to do estimation of a population by analyzing the sample given. I learn more knowledge about coding and conducting test using RStudio. I also realized that the bigger the size of the sample, the more accurate of the estimation of a population.
