About the Course
In a world flooded with data, one truth remains: if it’s not clean, it’s not useful. Most organizations are sitting on piles of potentially valuable data, but poor preparation turns it into a liability. From misaligned formats to inaccurate entries, raw data is rarely ready for analysis. What distinguishes confusion from clarity? This can be achieved through the implementation of intelligent and repeatable cleaning processes.
This training takes you from overwhelmed to in control. You’ll learn how to identify common issues, clean data efficiently, and structure datasets that work across tools, reports, and systems. No fluff. You will acquire the necessary tools, workflows, and practical experience to convert raw data into analysis-ready gold. Whether you're managing survey results, operational metrics, or monthly financials, you'll walk away with the confidence to prep and clean data that delivers.

National Population and Housing Census (RGPH3) Data Validation 2024Institut National de la Statistique, des Études Économiques et Démographiques (INSEED)
For the third general census (RGPH3), INSEED implemented rigorous data cleaning protocols to process records for an estimated population of over 20 million. The project involved identifying duplicates and correcting inconsistent demographic entries collected via mobile tablets across Chad's 23 regions.
Ensured the accuracy of the national database used for the 'Tchad Connexion 2030' development plan and international aid allocation.

Regulatory Quality of Service (QoS) Data Audit 2023Autorité de Régulation des Communications Électroniques et de la Poste (ARCEP)
ARCEP conducted a massive data analysis exercise of network logs from major operators (Airtel and Moov Africa) to verify compliance with service quality standards. This required cleaning raw technical data to filter out external interference and isolate operator-side performance metrics.
Resulted in a 5 billion XAF fine for Airtel Chad in 2023 for failing to meet cleaned data benchmarks for network availability and call drop rates.
