SECI Probability & Statistic Data Analysis

In the project 2, I learnt how to carry out analysis such as regression analysis based on the 2019 World Happiness Report. Throughout the process of analysis, I learnt how to define all the variables and make a clear conclusion to explain the findings from the analysis. Besides, I learnt how to write R script on Rstudio to do calculations and plot scatter plot graph. I also realise that the skill of using Rstudio is very important because the dataset is too large and we can use Rstudio to calculate all the results in a faster way. In a large dataset, there are so many variables that need to be considered, so we must focus on tiny details and repeat all the calculations again to avoid any mistakes.
