4.3. Exploratory factor analysis (EFA)
Factor analysis can only be implemented when the obtained data must ensure that
the KMO coefficient falls within the range of [0.5; 1] and that Bartlett’s test is
statistically significant.
Table 3. KMO coefficient and Bartlett's test
Kaiser-Meyer-Olkin Measure of Sampling Adequacy. .688
Bartlett's Test of Sphericity Approx. Chi-Square 1193.986
df 105
Sig. .000
The KMO test results show that the KMO coefficient is 0.688, and Bartlett's test
is statistically significant (Sig. < 0.05). Therefore, the data are suitable for conducting
factor analysis.
