Module description

This module aims to provide students with the necessary quantitative skills to enhance performance in other first year modules and to prepare them for their second and third years.


Students will develop their skills in areas including experimental design, data handling, display and interpretation, basic statistical analysis, and computational data analysis.

Module aims

The aims of this module are:



  • To demonstrate an understanding of the scientific method, experimental design and investigation in the biosciences.

  • To use scientific units and simple algebra and demonstrate understanding of logarithms, exponentials, geometry and elementary calculus.

  • To use basic IT systems effectively for data handling and presentation.

  • To analyse data from experiments and draw sound conclusions about the underlying processes using their understanding of mathematics and statistics.

  • To analyse biological data using the R programming language.

Module learning outcomes

By the end of this module, students will be expected to be able to:



  1. Define the straight line joining two points, or passing through one point with a known slope, in the form y = mx +c and determine the value of the slope m.

  2. Understand the relationship between logarithms and indices.

  3. Define logarithms and solve equations with indices (e.g. 3z = 9) using logarithms.

  4. Understand the use exponential, power law and growth models in biological applications.

  5. Use simple calculus and calculate slopes of lines (differentiation) and areas under lines (integration).

  6. Use differentiation to locate stationary points, maximum and minimum values of a function.

  7. Determine the differential of exponential functions.

  8. Differentiate composite functions using the chain rule.

  9. Differentiate products and quotients.

  10. Understand how to apply differentiation to connected rates of change.

  11. Apply integration and differentiation to biological examples.

  12. Formulate a simple statement involving a rate of change as a differential equation, including the introduction if necessary of a constant of proportionality.

  13. Perform simple scientific mathematical calculations relating to molarity, concentrations and dilutions.

  14. List the different types of variable, explain the distinction between them, and, for a given variable, say what type it is.

  15. Produce frequency distributions from raw data, and to decide whether a tabular or graphical presentation is appropriate.

  16. Present data correctly in tabular form.

  17. Describe the different forms of graphical presentation, decide which one is appropriate for a given purpose and construct and present correctly different types of graphs.

  18. Define, calculate, report and know when to use simple descriptive statistics (i.e. mean, median, mode, range, standard deviation and variance).

  19. Explain why measurements of biological material are variable and explain the consequences it has for biological investigations.

  20. Define the terms sampling unit, sample, population, statistic and parameter and explain the relation between them.

  21. Explain the need for other essential elements in the design of a sampling programme or experiment, replication, independence and the avoidance of pseudoreplication and bias.

  22. Describe the main properties of normal distributions and explain their biological relevance.

  23. Explain why a parameter can only be estimated and what is meant by the reliability of the estimate of a parameter.

  24. Calculate and report, in the correct way, a standard error for a sample mean and explain how this interval estimate quantifies reliability.

  25. Define and explain the meaning of the following terms; parametric and non-parametric data, null hypothesis, alternative hypothesis, test statistic, sampling distribution, significance level, rejection region, critical value, decision rule.

  26. Use these terms to explain the general principle of an hypothesis test.

  27. Explain the meaning of one-tailed and two-tailed hypothesis tests and the limitations of their use.

  28. Interpret and use tables of critical values.

  29. Use relevant software to analyse and describe simple data sets with tables and graphs.

  30. Use relevant software to carry out the correct and appropriate statistical tests and correctly interpret the output.

  31. Present the results of statistical procedures clearly in a form suitable for a scientific paper.

  32. Read and write files with biological data in a computer using R33.

  33. Use basic functions to analyse and produce graphs.

Exam format definitions

  • Remote, open book: Your exam will take place remotely via an online learning platform. You may refer to any physical or electronic materials during the exam.
  • In-person, open book: Your exam will take place on campus under invigilation. You may refer to any physical materials such as paper study notes or a textbook during the exam. Electronic devices may not be used in the exam.
  • In-person, open book (restricted): The exam will take place on campus under invigilation. You may refer only to specific physical materials such as a named textbook during the exam. Permitted materials will be specified by your department. Electronic devices may not be used in the exam.
  • In-person, closed book: The exam will take place on campus under invigilation. You may not refer to any physical materials or electronic devices during the exam. There may be times when a paper dictionary, for example, may be permitted in an otherwise closed book exam. Any exceptions will be specified by your department.

Your department will provide further guidance before your exams.

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
