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.


Anne Hasted began her career as an academic statistician at Reading University, leaving in 1989 to set up Qi Statistics Ltd offering statistical support to research and industry. She has over 25 years’ consultancy experience in the food, beverage and personal products industry, particularly in the area of product improvement and is an experienced trainer with a worldwide reputation for “user-friendly” training.
