No, higgle, it isn't like that at all. The reason for grouping people into age groups is on the basis of group dynamics. When you are running a group of consumers, having them all of a similar age in one group makes it much easier, as they are more likely to share similar views. So for example, we would never mix an 18 year old with a 65 year old, as their lifestyles/aspirations are very likely to be hugely different.
You have no idea on this project (and neither do I, as it isn't anything to do with me
) how many other groups they were running, and therefore how many different age groups the project was covering off.
And, with respect, you have no idea what the other criteria were that they might have used to recruit you.
It is very, very unlikely that age would have been the only factor. Other things that they might have included could have been (off the top of my head):
- when you last shopped in Joules
- how much you spent on your last shop
- how far away you live from a particular branch of Joules
- where else you shop
- what your attitudes towards fashion are
etc
And, with the greatest of respect, they probably do have quantitative data telling them how much different types of consumers are worth to them.
I am not perpetuating any myth here - these are the facts about how market research projects are run. To say that it is discriminatory in any way is, frankly, rather silly.
The limits on the number of people included in any research project are always dictated by the number of places available - (usually) 8 people in one group, and most likely to be around 4-8 groups on any one project.
