This
course forms a hands-on introduction to those statistical methods needed by a
sensory scientist. Mainly based around the use of SENPAQ and XLSTAT software,
attendees will gain practical experience using real-life examples and will be
able to save their work to take away with a free copies of SENPAQ and XLSTAT so
they will be competent to start using their expertise from day 1 after the course.

ABOUT THE LECTURERS Dr. Hal MacFie is
a statistician by training, with an international reputation in the areas of product
assessment and consumer research. Author of over 100 scientific publications and
three books, he was Head of Consumer Science at the Institute of Food Research,
Reading England, before becoming Director of the Institute. Dr. MacFie is now
an independent consultant, Visiting Professor at Reading University and European
Editor of Food Quality and Preference. Anne Hasted began her
career as an academic statistician at Reading University, leaving in 1989 to set
up Qi Statistics Ltd offering statistical training and consultancy support to
research and industry. She has wide training and consultancy experience in the
food industry, particularly in the area of product improvement.
