Program Professional Framework

Professional Certificate in Data Analysis Techniques

Program Overview

Sound analysis starts with understanding data before applying any tool. This foundation-to-practitioner programme covers the core techniques every analyst should master: data types and collection, sampling, cleaning and validation, descriptive statistics, exploratory analysis and visualisation, probability and distributions, confidence intervals, hypothesis testing, correlation and simple regression, and clear reporting of findings. Exercises use Excel and an introduction to Python on datasets from HR, finance, customer service and operations.

Learning Outcomes

✓Assess a dataset for completeness, accuracy and consistency and document cleaning steps.
✓Summarise data using measures of central tendency, dispersion and distribution shape.
✓Explore relationships through cross-tabulations, scatter plots and correlation coefficients.
✓Calculate confidence intervals and perform hypothesis tests for means and proportions.
✓Fit and interpret a simple linear regression for a business variable.
✓Write a short analytical report that states the question, method, findings and limitations.

Applied Project & Assessment

Applied Project

Participants analyse a supplied organisational dataset end to end: data quality assessment, descriptive and exploratory analysis, one hypothesis test, a simple regression and a two-page analytical report with recommendations.

Assessment

Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
