KOI Statistics and Data Analysis Report: Fuel Price Analysis, 2019

This report presents a comprehensive statistical analysis of fuel prices, addressing a business problem for NRMA. It begins with an introduction to fuel price data collection and the potential for biases. The report examines two datasets: a secondary dataset from the Australian Government Open Data and primary data collected through surveys. The analysis includes descriptive statistics, hypothesis testing (z-score and ANOVA), and graphical representations (histograms and bar charts) to understand the distribution of fuel prices and compare prices across different brands. The report investigates the shape of the price distribution, tests hypotheses about average fuel prices, and compares prices across major brands. The analysis of the second dataset involves a survey of colleagues' preferred fuel stations. The report concludes with a discussion of the findings, recommendations for NRMA's media reports, and suggestions for future research, emphasizing the importance of location, weather, and economic factors on fuel prices.
