๐งช Labs

- Correlation Practice Problems where I was given 3 datasets and had to calculate the correlation between the two variables using both the covariance method and the computational method.
- Regression Practice Problems where I was given 3 datasets and had to produce the regression equation for u predicting v and a graph of the regression equation for u predicting v using -1SD, X, and +1SD.
- R Intro Lab 5 where I had to explore, visualize, clean, and model Texas housing data
- CG Lab 5 where I explored the dataset, visualized variables of interest, cleaned the data, and modeled the data.

๐ฏ Exam

- Module exam had 26 questions: fill in the blank, true/false, and multiple choice (some with more than one answer). You can take the exam as many times as needed to get the score you want, but each test has different questions. I took the exam 3 times. Final score was 100%. You have until the end of the semester to take all your exams.
