This project analyzes the FIFA Legacy Players dataset using R and data visualization techniques. The report explores relationships between player age, overall rating, potential, market value, wages, playing positions, clubs, and nationalities through a combination of scatter plots, bar charts, box plots, histograms, a correlation heatmap, and an interactive Plotly visualization. The objective is to demonstrate how visual analytics can uncover meaningful insights into professional football player performance and characteristics.

It is known from studies of pulmonary function in adults who are long-term smokers, that smoking impairs lung function. It is of interest to determine whether early lung damage in seen in child smokers. To address this question, a study was conducted to measure the lung function of 654 children seen for a routine check-up in a particular paediatric clinic. The children participating in this study were asked whether they were current smokers. Other data collected include the measurement of age, height and sex.

Este estudio presenta un análisis estadístico descriptivo de un conjunto de variables macroeconómicas correspondientes a la economía de Estados Unidos durante el periodo comprendido entre 1919 y 2026, a partir de información obtenida de la base de datos Federal Reserve Economic Data (FRED). El análisis se centra en variables como el Producto Interno Bruto (PIB) nominal y real, la tasa de desempleo, la inflación subyacente, la tasa de interés, el consumo de los hogares y la producción industrial. Para describir el comportamiento de estas variables se emplean herramientas de estadística descriptiva, incluyendo medidas de tendencia central, dispersión y forma, así como representaciones gráficas que permiten identificar la distribución de los datos y posibles patrones de comportamiento. Este análisis constituye una primera aproximación al comportamiento histórico de la economía estadounidense y sirve como base para explorar relaciones entre sus principales indicadores macroeconómicos.

An interactive exploration of what influences Dota 2 match outcomes, which hero pairings perform best, how draft relationships form networks, and where global attention concentrates. Built with OpenDota data, Google Trends, predictive modeling, PCA, clustering, and interactive Plotly visualizations. The project emphasizes interpretable evidence over certainty: an atlas, not an oracle.
