Reflection Project 2
RSS
In project 2, I got to learn about problem solving by doing correlation testing (my part) on dataset of superstore records in 2018. I did a testing if there were a relationship between the sales and profit, if the sales increase, the profit increases which is the hypothesis made before the testing. During the testing, I learnt more on how to use Microsoft Excel on creating tables and adding the numbers. Then, the programming part I used R studio which can help us a lot. For example, I can create a scatter plot of the profit on sales by coding it on R, which is mind-blowing. All the calculations I referred to the lecture notes given and it was handful. After completing the project, we did a brief presentation. Finally, the project was done successfully and I was glad and relieved that it was done pretty early despite the assignments and project in between this project. I was grateful to have groupmates that are easy to work with.
