Abstract:

Following a series of investigations undertaken into the methods of written surveys by the authors, this argument can be viewed as correct only up to a certain point. When written surveys are entailed , the requisite degree of evaluation is dependent upon a series of ranges of influences which determine the limits. Points to be born in mind include the type of the target group, the kind of characteristics under survey and the manner of formulation of the questions as well as the way the interrogatory media are set up.
