Statistical inference estimation and hypothesis testing
Build practical command of Statistical inference estimation and hypothesis testing for Data Science and Statistics Pathway: explain the concept, make applied-assessment-ready decisions, complete a hands-on public or synthetic dataset, statistical notebook, database, visualisation tool, model-validation suite, and governance worksheet exercise, and produce evidence that supports the Data Scientist, Statistician, and Decision Analyst Learner role. Work at Level 4 aligned depth by connect statistical inference, databases, reproducible programming, modelling, and guided data products.
Introductory higher education comparable in challenge to a CertHE, HNC, or first undergraduate year.
Assessment evidence: Reproducible data-analysis and statistical-modelling capstone.
Academic level alignment describes learning depth. It does not confer university credit or an awarded qualification.

Course reader preview
1. Population, sample, variable, distribution, estimand, and measurement
Statistical inference estimation and hypothesis testing is studied through population, sample, variable, distribution, estimand, and measurement. In this module, learners connect that foundation to data-generating processes, statistical reasoning, computation, uncertainty, prediction, causality, communication, and governance. At Level 4, the expected performance is to analyse connected principles in a guided higher-education task; claims must follow from stated assumptions and relevant evidence rather than from terminology alone. Unlock the paid lesson to read the complete method, worked example, misconception analysis, glossary, evidence task, and answers.

2. Data quality, missingness, bias, confounding, and leakage
