Homework #1-Tan Guan Lin

3 Things I learnt today:

1. How to use code using RStudio(creating functions and using the functions to make sense of data)
2. How to use data and analyse them to find the standard deviation and the correlation.
3. Applications of data science such as recommendation and transportation.

1 Question I still have:

How does the two sample and three sample chi-squared test work?
