Two tests, the Kaiser-Meyer-Olkin Measure of Sampling Adequacy (KMO) and Bartlett's Test of Sphericity, were run to determine the appropriateness of including factor analysis in this research.
To determine if the data were appropriate, we used Bartlett's test of sphericity and the Kaiser-Mayer-Olkin measure of sampling adequacy.
Also the Bartlett's test of sphericity (Bartlett's test) was used, testing the hypothesis of the correlation matrix being the identity matrix, i.
Table 2 showed the results of the KMO and Bartlett's Test to indicate the suitability and validity of data at hand for detecting structure and creating constructs as per the response pertaining to the questionnaire.

The effect of the treatments was checked by applying analysis of variance (ANOVA), with Bartlett's test used for its validation, which verifies a basic premise for the realization of ANOVA, the homogeneity of variances among treatments (RIBEIRO JUNIOR, 2001).
This study not only uses an adequate sample size of 147, but also makes use of Factor Analysis' built-in reliability checks such as Kaiser-Meyer-Olkin (KMO) and Bartlett's test to lend statistical credence to items such as the sampling adequacy as well as the strength of relationships between variables, respectively.

The Bartlett's test of Sphericity showed that nonzero correlations exist at the significance level of 0.
