Enabling informed decision-making through effective presentation

Covering Assessment Criterion 1.5 of 3CO02 Principles of Analytics, this video addresses the practical challenge of presenting data findings in formats that genuinely support organisational decision-making. Rather than treating chart selection as the endpoint, the video examines the supporting elements that make visualisations interpretable and credible — including titles, axis labels, data source attribution, and explanatory notes that situate findings within their broader context. The treatment of a fifteen per cent absence rate serves as a concrete illustration of why contextual framing, such as comparison with previous periods or industry benchmarks, determines whether a figure is meaningful or misleading.

The video covers four distinct presentation formats — written reports, slide-based presentations, dashboards, and executive summaries — and addresses how the demands of each format shape decisions about visual complexity, level of detail, and the relationship between verbal and written explanation. A worked example involving employee retention draws on three chart types simultaneously: a line graph tracking turnover trends, a bar chart comparing departmental rates, and a pie chart representing reasons for leaving. This multi-visualisation scenario illustrates how different diagrammatic forms — the pie charts, bar charts, and line graphs specified in the unit's indicative content — can work together to build a coherent analytical narrative rather than operating in isolation.

Accessibility considerations form a distinct section of the video, covering colour contrast, colour vision deficiency, the use of patterns and labels as alternatives to colour coding alone, font sizing, and alternative text for screen readers. The video also addresses the communicative obligations that accompany data presentation: foregrounding the key message, connecting findings explicitly to the decisions they inform, and acknowledging the limitations of the data honestly. These elements are framed not as presentational polish but as conditions for evidence-based practice within an HR context.
