This report presents two applications of the Chi-Square test using R: Chi-Square Test for Independence, applied to the UC Berkeley admissions dataset (UCBAdmissions), to determine whether there is a significant relationship between gender and admission status. Chi-Square Goodness-of-Fit Test, applied to the Hair and Eye Color dataset (HairEyeColor), to evaluate whether the distribution of eye colors follows a uniform distribution. The analysis includes data exploration, computation of Chi-Square statistics, p-values, degrees of freedom, and interpretations of the results to support statistical decision-making.

This project applies time series forecasting to three datasets — ATM cash withdrawals, residential power usage, and hourly waterflow. Using the fpp3 framework, ETS and ARIMA models were fit to analyze patterns, generate future forecasts, and visualize results. Forecast outputs are exported to Excel for further validation.
