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, Anne Hasted
10 to 12 February 2009
Venue: Paris: MEDIASITE
Course Organiser
Hal MacFie
Bristol
For course details and registration email: hal@halmacfie.com
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.
