ABSTRACT
In studies 3-5 an attempt was made to apply two objective types of measurements-the TTR and information measurement-to fa<;ades, and to compare their efficiency. It was shown that the two types of measurements, although they gave comparable results, had their drawbacks. The universe of the signifier of these fa<;ades could, with these measures, be constructed as an oppositional structure of high and low objective measurements. Thus it has become possible to consider the question of whether the two universes-the signified of subjective impressions and the signifier of objective indices-are coordinated, that is, constitute a semiotic structure. Since in both groups of studies the results are series of measurements taken on the same objects, the obvious way to test the significance of any coordination between the two universes would be to calculate the covariance of the two sets of measurements. A test of the null hypothesis (that there is no semiotic structure) may thus be obtained by the calculation of correlation coefficients for the paired subjective and objective sets of fa<;ade measurements . However, before the relevance and the results of these calculations are shown, an interesting study from the literature will be discussed which used a similar approach.
