approx. 10 hrs

8 topics

21 concepts

Develop proficiency in analysing univariate data through the statistical investigation process.

Available in


Univariate data analysis and the statistical investigation process is a learning program where students develop an ability to organise and summarise univariate data in the context of conducting a statistical investigation. We help students understand the concepts and techniques used in univariate data analysis and the statistical process. Students will explore the statistical investigation process in practical contexts, effectively interpreting and communicating results using appropriate statistical terminology.
