Introduction

Scientific visualisation is classically defined as the process of graphically displaying scientific data (Tufte, 1983), often in the form of charts, graphs, and maps. By visualizing data in this wa[...]

Objectives

  1. To show why R is so used and useful to explore the importance of data visualisation in introductory statistics and econometric courses.
  2. To provide practical tips and strategies for instructors looking to incorporate data visualisation into their courses.
  3. Easy data visualisation with the packages esquisse, modelsummary and ggstatplot for graphical displays.

Methods

The packages esquisse (Meyer & Perrier, 2023), modelsummary (Arel-Bundock, 2022) and ggstatplot allow to interactively explore data by visualizing it[...]

The pedagogic approach to teaching graphics and data visualisation

Students in introductory courses in business statistics from degrees of Business Administration, Tourism and the Double Degree in Labour Relations and Human Resources were required to create data v[...]

Results and feedback

The benefits of the training were emphasised in student comments and feedback from the end-of-semester course evaluation. Furthermore, students were allowed to assess their progress in statistics T[...]

Conclusions

Our findings suggest that the use of statistical software to create data visualisations helps students learn statistics concepts by providing alternative ways to represent data. Especially, the use[...]

According to the students’ feedback, the most useful and effective types of data visualisation for teaching introductory business statistics were: scatterplots, [...]

Data visualisation can lessen difficulties in learning statistics and econometrics by providing opportunities to illustrate analytical findings in graphic form. The use of real-world data is to str[...]
