*4.2. Statistical Links between the Results*

By means of the scatter graphs, it was possible to analyze the links between the technical data of the dwellings (quantitative data) and their morphological characteristics (qualitative information). These graphs show that the thermal transmittance (14) is the value that influences most in the equivalent energy (10 and 11), as the shape factor (9) and the indoor humidity (7) also do.

They have to read in terms of probability. This means that, for example, as can be seen in Figure 6, the sum of the wind speeds (1) of the plank house locations (192.61 km/h), the adobe house locations (150.01 km/h), the hogan locations (126.78 km/h) and the wigwam locations (155.57 km/h), which is equal to 624.97, is higher than the corresponding sum of the rest of the dwellings (548.19). The aforementioned dwellings are situated in the direction of the wind speed vector (1), and that is the zone of the graph where the highest sum of wind speeds is concentrated. This way, the position of the dwellings and the species on the graphs must be understood according to this system. This method is very useful for analyzing vernacular architecture in general, since it allows for the discovery of the logic of its morphological features and its links with its environmental circumstances. This would be the case of the research work developed by Varela Boydo and Moya [83]. It would allow us to identify which characteristics of the traditional windcatchers respond to cultural features and which ones are related to their adaptation to the proper circumstances of each geographical and climatic zone. The same could be determined about the Malay traditional houses analyzed by Ghaffarianhoseini, Berardi, Dahlan and Ghaffarianhoseini [84]. This method allows us to transform the morphological features of the Malay houses, such as the characteristics of their roofs, into numerical data. This way, it would be possible to establish the relation of this distinguishing element with the climate and the environmental information of each specific region.
