Ernie and others I often seem to react when all others have finished the topic. It feels nice having a strong impulse to make clear things who are in a dark corner. To do research using a survey or a questionaire is not at all easy. However that does not mean that nothing can be done. First I want to show some of the difficulties one runs into. In creating a questionaire there are two possibilities. 1. Closed questions can be used. The subjects can answer yes or no or they can be given some choice on a 5 points-scale. 2. The other possibility is to use open questions. The subject tells his own story and can use his own words. The first method seems the easier one. It results in a matrix with numbers and the mathematician feels happy and starts computing. Most people in trying to complete a questionair have felt irritated. The questions seemed to be wrong: the real answer often seemed to be: that depends....To prevent this, knowledge about the topic that is investigated is needed. Besides, it is amazing difficult to formulate questions meaning the same for all people. So possessing this matrix of numbers, the researcher can't know what they really and exactly mean. Much pilot study has to be done to overcome this problem. However, having done so, the troubles don't stop. The next step is to compute which relations exist between the variables. One can expect only weak relations. When very strong ones exist they need no search; they can be seen at once. But even if the numbers in your matrix are actually 100% random you may find some weak relations by chance . So the margin to find anything that is something is very small. It may be clear by now, that this kind of investigation is hard to execute and that the road to clear conclusions is full of pittfalls. The second form of investigation, the open question one does not give all those troubles. It is a more modest approach, more as a journalist. It does not result in clear cut scientific statements but some interesting material can be expected. In the former method interesting things easily disappear. Ernie or others who are interested think it over. When you want to make an inventarisation of some sort 10% of the listembers wanting to cooperate is sufficient. Of course it is a biased sample but all the listmembers together are so too. Plans like this need some time to brood over. Ida Kamphuis Holland
