Final report

This report presents a comprehensive analysis of website traffic and user behavior using a dataset of 2,000 user sessions. Key metrics include page views, session duration, bounce rate, time on page, previous visits, conversion rate, and traffic source (direct, organic, paid, referral, and social). The analysis covers data quality assessment, traffic source performance comparison, engagement metrics relationships, statistical testing (t-test, ANOVA, and regression), and visualizations (bar charts, scatter plots, histograms, boxplots, correlation matrix, and ECDF). Findings identify organic as the top traffic source by volume, referral as the most engaging by session duration, and repeat visitors as significantly higher converters. The report concludes with outlier detection and a multi-metric comparison across traffic sources.

Instructions The US Geological Survey publishes a list of Strategic Minerals ( https://www.usgs.gov/news/national-news-release/us-geological-survey-releases-2022-list-critical-minerals ). Having a secure supply of these minerals is essential to our security and economic prosperity. However many of these minerals are sourced from outside of the US. This assignment is to develop a reference catalog of the source or sources of each of these minerals and a judgement on the reliability of each source under stressed circumstance (e.g. war, economic crisis, etc.) DATA608

Implementasi konsep statistika menggunakan R, meliputi simulasi Teorema Limit Pusat (Central Limit Theorem), ketakbiasan penduga parameter, serta pembentukan selang kepercayaan. Simulasi dilakukan pada beberapa distribusi seperti geometrik, eksponensial, seragam, dan normal untuk melihat perilaku distribusi rataan sampel, ragam sampel, serta ketepatan interval kepercayaan terhadap parameter populasi. Analisis disajikan melalui perhitungan numerik dan visualisasi histogram maupun grafik interval kepercayaan.
