This section organises the biostatistics material for BCB744 into a single, part-based structure.

Use the detailed module page for timetable, assessment, and broader module context:

1.1 What This Section Does

The biostatistics block introduces the logic of statistical reasoning in biology and ecology, and then moves into the standard methods used to summarise data, test hypotheses, and build interpretable models.

The emphasis is on choosing methods that match biological questions, understanding assumptions, and interpreting results in scientific rather than purely mechanical terms.

1.2 Chapter Structure

The chapter sequence moves from:

  1. statistical thinking and exploratory data analysis,
  2. core hypothesis tests,
  3. regression and model building,
  4. dependence and model extensions, and
  5. reproducible workflow.

1.3 Part I. Statistical Thinking and Data Foundations

  1. The Statistical Landscape
  2. Summarising Biological Data
  3. Visualising Data
  4. Distributions, Sampling, and Uncertainty

1.4 Part II. Core Hypothesis Tests

  1. Statistical Inference and Hypothesis Testing
  2. Assumptions and Transformations
  3. Inferences About One or Two Populations
  4. Analysis of Variance
  5. Correlation and Association
  6. Choosing the Right Test

1.5 Part III. Regression and Model Building

  1. Simple Linear Regression
  2. Multiple Regression and Model Specification
  3. Interaction Effects
  4. Collinearity, Confounding, and Measurement Error
  5. Model Checking and Evaluation

1.6 Part IV. Dependence and Model Extensions

  1. Pseudoreplication
  2. Dependence and Mixed Models
  3. Generalised Linear Models
  4. Nonlinear and Flexible Regression
  5. Prediction, Explanation, and Regularisation

1.7 Part V. Reproducible Practice

  1. Reproducible Workflow

1.8 Assessment and Practice

Use these pages alongside the chapters:

1.9 Relationship to Intro R

This material assumes the practical skills developed in the first half of the module.
