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.

We believe
these to be the best computer training facilities
in Manhattan. The MicroTek New York City training
center is located in the heart of the financial
district in downtown Manhattan just 2-blocks
south of the New York Stock Exchange. In addition
to purpose built computer training facilities
there are ample computers to catch up on e-mail
at the breaks and over lunch..
Close proximity
to hotels, public transportation, and points
of interest such as the Statue of Liberty and
Ellis Island makes the computer facility a great
location for your next training event.
