Learning Outcomes

On successful completion of this module students should be able to:

Plan and execute a computational scientific experiment.

Demonstrate an ability to write small programs in Python

Demonstrate an understanding of the potential biases and sources of error in science.

Analyse a data set (process data, apply appropriate tests, calculate summary statistics, plot results).


The module introduces the student to Python and uses Python as programming language to solve various data analysis-related tasks. This leads into studying data analysis as the main topic in the second semester.

Brief description

This module first introduces students to the Python programming language and to the use of Python and its library modules for processing scientific data. The module then goes on to cover the Scientific Method, the basic structure of a scientific experiment and making and testing hypotheses, with illustrated examples of good and bad practice. Also discussed are difficulties in achieving randomness, sources of bias during sampling and choosing appropriate statistical testing methods for various types of study.


Semester 1:
• Introduction to the Python language: types, variables, flow control statements, loops. The interactive interpreter and evaluation of simple expressions.
• Python data structures: Lists, tuples and dictionaries.
• The NumPy module: Data arrays and vectorised operations.
• Functions: Function definition, calling, parameter passing and value return.
• Organising code: Generating documentation. Handling exceptions. Creating and using modules.
• Python objects and classes: Defining and using classes. Working with objects.
• File handling: Reading and writing text and csv data files. Extracting and processing data from web pages.
• Plotting: Manipulating data and plotting results. Use of the matplotlib module.
• Review and revision classes.

Semester 2:
• The Scientific Method: Structure of a scientific investigation. Hypotheses. Occam's razor. Controls. Correlation vs. causation. Falsification. Controlled and double blind trials.
• Introduction to the scipy and pandas modules: Working with DataFrames and basic statistics.
• Randomness: Sources of randomness and random number generators. Random distributions. Random sampling.
• Descriptive statistics: Central tendency and spread. Discrete and continuous measurements.
• Hypothesis testing: T-test. Confidence interval. p-value. Chi-square test.
• Correlation.
• Sampling: Biases. Bootstrap. Monte Carlo methods.
• Application to real data and hot topics in science.
• Review and revision classes.
