UIC comfort tests - VTI

10 General evaluation of local comfort results10.1 Evaluation of votesThe 32 test subjects were divided into eight groups (A, B, C, .., H). The eightgroups shifted position in the train during the stops in Firenze. There were sevendifferent positions in the train, which means that one group of four was dividedinto two subgroups of two and joined another groups during the test runs.The recordings of votes were from these seven positions. Before furtheranalysis, the individual votes from these seven positions were averaged to a meanvote for the position in question. The distribution of these mean votes is notnormal, but can be regarded as approximately normal, see Figure 10-1 and Figure10-2 for the both directions of travel. Table 10-1 shows the difference in meanvalues in votes for the two directions.400VOTE300200Frequency10001,001,502,002,503,003,504,004,505,00Std.
