Statistics for Consumer Research

Product code: CON2-0

Duration: 1 - 3 days

Pre-requisite
Only the most basic statistical knowledge is assumed.

Course Summary
We offer training in three, one day modules, any one of these can be run on its own or combined with the other modules into a two or three day training course. Each module covers key statistical techniques used in the analysis of data collected in consumer research studies to compare products or brands. Emphasis is placed on the interpretation of the statistical tests and mathematical details are kept to a minimum. The training is suitable for both market researchers and consumer scientists working on product evaluation and optimisation.

Software
We base the training around a suitable statistical software package. We recommend XLSTAT®, JMP® or EyeOpenR® but can advise on appropriateness of other software packages.

Flexibility
We can customise module content to specific requirements.
