PROBABILITY & STATISTICAL DATA ANALYSIS
In this course, we need to finish a Group Project about doing data analysis of a dataset by using R programming. R is a language very similar to python but more for data analysis. At first we chose a dataset (Obesity) from the link provided in the instruction, after that we started to separate task. My task in this project is using R to calculate the Chi-Square, and it's very easy by using R. When we calculate manually we need to calculate one by one, if for some data below 10 or 20 is okay, but how about using the dataset that has a thousand? But by using i R we can calculate all the data by just using few lines of codes. Beside Chi-Square, we can also use the R to do a lot of different types of analysis of dataset. After finishing this project, i can do some analysis of dataset using R and the slide of R programming provided by dr also help me a lot in finishing this project.
