Also, graduated symbol plots of factor scores of the element associations obtained by factor analysis were produced to examine their relationship with the basin geology.
In addition, the construct validity of the STAI, as measured by factor analysis were found, the correlation between items (KMO) score.824 (>.30) and p=.000.
The first five eigenvalues obtained by factor analysis were 13.51, 2.64, 1.48,.99, and.94, while the first five random eigenvalues obtained by means of parallel analysis were 1.56, 1.48, 1.43, 1.38, and 1.34.
Each factor grouping had good internal consistency, with Cronbach α equal to.82 for factor 1,.83 for factor 2. The median (interquartile range) scores as defined by factor analysis were 1.0 (from 0.5 to 1.0) for factor 1, medical reasons and 0.0 (from 0.0 to 1.0) for factor 2, non-medical reasons.
Each factor grouping had good internal consistency, with Cronbach α equal to.90 for factor 1,.86 for factor 2 and.87 for factor 3. The median (interquartile range) scores as defined by factor analysis were 5.0 (from 5.0 to 5.0) for factor 1, lung auscultation, 3.0 (form 2.8 to 4.0) for factor 2, non-medical reasons, and 4.0 (from 4.0 to 5.0) for factor 3, unusual or not.
Perhaps more importantly, identifying how different attitudes towards transport more generally (the latent variables identified by factor analysis) are associated with views on safety would allow targeted material to be developed to educate and provide information to users and non-users.
An additional dimension suggested by factor analysis was "service planning" which has been found to have lower internal consistency reliability.
The number of factors to retain is determined by the number of eigenvalues, for which the real eigenvalue obtained by factor analysis is greater than the random eigenvalue.
The principle of factor loading to amenities, assets, and durables derived by factor analysis is used for the computation of the wealth index (20).
The assessment of the internal structure of a scale by factor analysis is a method used to establish the construct validity of a tool [ 19, 20].
