Hands on Sensory Statistics Course

Designed to give you the knowledge, practice and the tools to do your own design, analysis and interpretation of sensory data. Hands-on exercises, free XLSTAT and SENPAQ software for participants to take away.

Hal MacFie and Anne Hasted

17 to 19 October 2018
Venue:Microtek Labs

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 free copies of SENPAQ and XLSTAT so they will be competent to start using their expertise from day 1 after the course.

It will also be possible to attend this course from the comfort of your home or office using the Virtual Training Room Facility.


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.

Facility Description:

The building is in the Loop, at the corner of Franklin and Monroe, one block from the Sears Tower. The facility is 3 blocks from both the Union and Ogilvie train stations. The building is 29 stories with black exterior pillars and dark windows. The entrance to the building is on the Franklin Street side, through the revolving glass doors. There is a large open lobby that is shared with other tenants. MicroTek is on the 5th floor.

Please see Chicago Hotels for details of hotels nearby with discounted rates. We usually stay at La Quinta which is next to the facility and very reasonable with a free breakfast.  However Club Quarters is also close and gets good scores from attendees.
