Students preparing for professional statistical work can benefit from experience with real
statistical problems presented by real clients and requiring them to engage with the complete
problem-solving process without the usual cues of ‘textbook’ examples. We have used such an
approach in a capstone unit in statistical consulting, asking students to write about their learning
experiences and to reflect on the ways in which such consultations helped them (or not) to
develop their professional statistical skills. A content analysis of students’ comments focusing on
engagement and motivation confirmed that students had generally positive views of their
experience and found the approach engaging and motivating. On this basis, we recommend
utilising real problems from real clients as a means of including authentic practice in a
professional statistics degree, with consequent benefits for students’ engagement and motivation.
INTRODUCTION – A CAPSTONE STATISTICAL CONSULTING UNIT
During the Australian Association of Mathematics Teachers Conference, in Canberra in
December 2014, the Chief Scientist of Australia, Prof Ian Chubb, related that when he was young,
the mention of being a mathematician or loving mathematics left him alone in any in social
situation! Mentioning a love of statistics would have created a similar effect, as statistics is
associated with mathematics in many people’s minds. One of the authors experienced a similar
scenario during her introductory talk to Bachelor of Social Science students, as she was
encouraging them to choose a statistics major. When she asked “who loves statistics?”, only a
single hand was raised from the groups of over 150 students, with most of the rest trying to look
the other way. Statistics as a discipline does not usually generate high levels of engagement and
motivation among students generally, nor even among students studying statistics.
When we were designing our capstone unit for the statistics major (Bilgin et al., 2011),
we aimed to give our students opportunity to confidently apply their statistical knowledge and
skills to authentic professional problems. We created a curriculum where they could expand their
communication skills, increase their confidence to continue learning, and develop their
professional and personal identity as statisticians. Our previous investigations have shown that
our students recognise these as key aspects of the unit (Bilgin & Petocz, 2013).
Our students come from mixed mathematical backgrounds. The actuarial students are
able mathematicians wishing to add a second major in statistics, while the science/business
students are not so strong mathematically, but have more experience with applied statistics.
Generally, none of them has had authentic experience of the messy nature of real statistics
problems presented by real clients who may not always give clear descriptions of their research
aims. Like all teachers, we aimed to engage this diverse group of students and motivate them to
do their best in this statistical consulting unit; in this aim we used a variety of approaches.
Firstly, we share our own experiences of statistical consulting with them, formally, as the
topic of the first class, and then informally throughout the course. Secondly, we bring guests into
our classes. Several times, guest researchers present real problems and ask the students for
comments and advice in solving them; this allows students to practice clarifying a problem and
explaining a solution. Other guests have statistical consulting experience, and they share this with
the class, highlighting the ‘human’ aspects of consultancy. Students work in groups during the
semester on larger consultancy projects, taking responsibility for the complete consultancy from
start to finish (though lecturers are available for discussion if needed). The reports of these
projects are used instead of examinations for final assessment. Such group project work in
statistics has been shown to increase engagement (Sisto & Petocz, 2012). The curriculum is
arranged to encourage students to develop their ‘soft skills’ and technical competence, and to use
the support of their peers and lecturers to develop their expertise in the consulting process.
