**The Centre for Mathematical Sciences**** research seminars and events are listed below.**

The four main seminar series are in applied mathematics, pure mathematics, statistics and theoretical physics. Visit the centre's webpages for the latest seminar updates and information.

**Tuesday 18 September, 16:30-18:00 (Room tbc, Rolle Building): Statistical Problem Solving: the Art and Science of Learning and Teaching from Data**

- Speaker: Christine Franklin, School Statistics Ambassador, American Statistical Association

The Teaching Statistics Trust Lecture 2018 is for teachers of statistics in all subjects in schools and colleges. The event is free to attend and refreshments are provided.

- Improve your teaching of statistical problem solving and data literacy
- Discover the art and science of learning and teaching from data
- Improve ways to teach statistics in AS- and A-level Mathematics
- Help teaching the Skills Challenge Certificate in social science subjects
- Take away useful teaching resources

**Abstract:** After nearly 40 years as a statistics educator, Christine often reflects about her professional experience with learning and teaching statistics – remembering the past and feeling guilt about how poorly she must have taught her students those first years, trying to stay current with constantly changing pedagogy and assessment in the present, and making predictions about the future. How often do you reflect about your experience as a statistics teacher? Christine often reflects on what a great feeling it is to start each day knowing we work with students and colleagues aiming to see those light bulb moments of understanding the usefulness of data and statistical reasoning skills, but also the importance of being a healthy sceptic of the interpretation of small and big data we are often presented with.

What are the lessons we have learned that will positively impact the data and statistical literacy of our students in the future? Christine has been fortunate to collaborate with amazing colleagues through the years who have enlightened and inspired her to learn these lessons to continue the journey for advocating data and statistical literacy in our society.

In this presentation she will discuss the art and science of learning and teaching from data (as she has experienced from writing four editions of *Statistics: The Art and Science of Learning from Data* and other resources specifically written for teachers) to help you improve teaching statistical problem solving and data literacy at the school level.

**Wednesday 17 October (start time: 13:00, venue tbc): Mini-symposium in medical statistics**

**Practical issues in medical statistics**

- Speaker: Gavin Koh (GSK)

**Abstract: **Statistical methods provide a variety of options for designing a clinical trial: for example, superiority, equivalence and non-inferiority. Selecting a design depends not just on statistical considerations, but contradictory clinical, regulatory and ethical considerations. After completing a study, secondary multivariate analyses are often performed and further choices need to be made: Which exposure group should be chosen as comparator? Or should you fit a no-intercept model? How should the independent variables be parameterised?

Tafenoquine is a new chemical entity being developed as a novel treatment for malaria. Gavin will illustrate these questions using data from a recently completed phase III trial of tafenoquine in malaria. This will be an interactive seminar with the audience asked to suggest and justify design solutions.

**Dietary intake in the early years and its relationship to BMI in a bi-ethnic group: the Born in Bradford 1000 study**

- Speaker: Samuel Mahoney (Covance)

**Abstract: **The number of infants, toddlers and children who were overweight increased from 32 million globally in 1990 to 42 million in 2013. This figure is predicted to rise to 70 million by 2025. In the UK it is estimated by 2020 that 20% of all boys and 33% of all girls will be obese. Using data from the Born in Bradford 1000 cohort this study aimed to assess relationships between dietary intake at age 12, 18 and 36 months and BMI Z-scores at age 36 months in a bi-ethnic group. Results indicate that dietary intake at 18 and 36 months was somewhat related to BMI Z-score at age 36 months and suggest the importance of early interventions aimed at establishing healthy eating behaviours.

Tea, coffee and biscuits will be served after the meeting.
