Module summary

This course will introduce students to basic techniques, which can be used to perform a preliminary investigation of data sets. Exploring data involves visualising the variables and relationships to help determine outliers, identify trends, suggest suitable statistical models and inform future data gathering.


This module gives students knowledge on how to explore and analyse data sets appropriate for differing data types. The module will provide students with opportunities to develop the skills for visualising and summarising data sets, and practise applying statistical analysis. As well as introducing students to archetypical methods, they will explore more novel approaches: such as kernel density estimation and principal component analysis.

Learning outcomes
On completion of this module students will be able to:

1. Use software to visualise data in different ways.
2. Calculate numerical data summaries.
3. Identify probability models for data.
4. Understand clustering in data and measures of distance.
5. Effectively visualise high dimensional data.
6. Understand through examples how visualisation of data can inform statistical model selection.

Skills outcomes
Skills developed in this module:

- Effective communication through visualisation of data.
- Interpreting data and making modelling decisions based on that interpretation.


1. Data types: Categorical, discrete, continuous. Data cleaning.
2. Graphical summary: Boxplots, Histogram, KDE.
3. Numerical summary: Location, variability, quantiles. Data manipulation.
4. Discrete distributions: Binomial, geometric, Poisson.
5. Continuous distributions: normal distribution, exponential, Uniform.
6. Bivariate data: Scatterplots, correlation. Linear regression.
7. Logistic regression and classification. PCA and dimension reduction.
8. Use a statistical software to import data and perform simple visualization, exploration and summary.
