Data-fit for factorial analysis. In the anti-image
correlation matrix, the KMO measure (Kaiser-Meyer-Olkin
Measures of Sampling Adequacy) values of all
questionnaire statements are checked; since the KMO
values of all statements enter into the interval 0,5-1, none
of the statements is eliminated from the analysis. The
general KMO measure of sampling adequacy, counted as
the mean of KMO of all statements, in this case is equal to
0,803; this shows a rather high data dispersion which can
be explained by the factors (the KMO measure can take
values from 0,5 to 1; the closer this measure is to 1, the
higher the sampling adequacy is). The value of Bartlett’s
test of Sphericity Sig. is 0,000, which also indicates that the
data, most likely, fit to the factor analysis (p
