R is a great computer programming language that is not difficult to learn, even for those who have no previous computer programming experience. It is a high-level language which means its instructions and commands are human-readable. It is known for its large world-wide community and its power in data and statistical analyses.
In this online day school you will learn how to perform several widely-used hypotheses and statistical significance tests and correctly interpret the results.
The day assumes prior knowledge of how to use R and RStudio. It contains explanation and implementation of several tests such as:
- t-test to determine if there is a significant difference between the means of two groups, which may be related in certain features, or to answer the question: is the mean of a vector different from a given value? This includes variations of the t-test.
- Kolmogorov-Smirnov test to statistically test the distribution of a variable.
- A/B test to establish which of two treatments, products, procedures, or the like is superior.
- Permutation test to compare an observed statistic to a resampled distribution and determine whether an observed difference between samples might occur by chance.
- ANOVA to test whether groupings in the data can be meaningful ways to understand the structure of the data.
- Chi-Squared test to test differences across a contingency table.
This training covers various theoretical and practical aspects of several hypothesis and statistical significance tests. You will learn what a test does, when to use it, how to use it and how to interpret its results.
By the end of the day you will have access to all course material (eg slides, code examples and so on).
Please note: this event will close to enrolments at 23:59 GMT on 17 March 2027.

IT requirements
We will be using Zoom for this event, and students and tutors will discuss and interact in real time. Joining instructions will be sent out prior to the start date. We recommend that you join the session at least 10-15 minutes prior to the start time – just as you might arrive a bit early at our lecture theatre for an in-person event.
Please note that this course will not be recorded.
