Скачать или смотреть Hierarchical Clustering - Visualisation (Dendrogram, Bar-chart, Heat Map)

In this video, we explore how Heatmaps, Dendrograms, and Bar Charts can be powerful visual tools in HR analytics, especially when analyzing employee absenteeism data. A heatmap provides a color-coded view of the data, making it easy to spot patterns, such as employees with high absentee hours or unusual transport expenses across different departments or age groups. The dendrogram, generated through hierarchical clustering, helps visually group employees based on similarities in variables like absentee hours, transport cost, and age—offering deep insight into behavioral patterns. Finally, the bar chart breaks down key metrics such as total absentee hours by department or job role, allowing HR professionals to pinpoint problem areas and act accordingly. These visuals are not just about aesthetics—they reveal critical trends that can inform decisions on employee support, policy changes, and resource allocation. Ideal for anyone looking to make sense of HR data through clear, impactful visualisation techniques.
