Background For this analysis, you will be working with quarterly municipal water demand data from 1996 through 2025, provided in “quarterly_water_usage.csv”. Over this period, water demand is affected by seasonal patterns related to weather and usage (such as higher demand during warmer months) as well as long-term changes like population growth and shifting consumption habits. As a result, this makes the dataset well-suited for time series analysis. By working with this data, you will explore trends, seasonality, and short-term variation in water demand and apply time series methods to better understand and model how water usage changes over time. Exam Structure Part 1: Exploratory Data Analysis & Trend Modeling Part 2:Seasonality and Differencing Part 3: (S)ARIMA Modeling Part 4: Forecast   **Please note: You are required to submit your final analysis as a PDF file. **   This exam will give you a practical understanding of working with environmental time series, as well as a chance to demonstrate your ability to apply statistical modeling techniques for forecasting such time series.
