The Reliability Test For The Assessment Tool

A second review of the measuring items for each TQM principle was conducted to minimize the redundancy of items that provided the same measurement. . As a result of the review, some measuring items were reduced. There were no modifications or translation for the measuring items. Table 2 includes the final number of items used after the pilot study was conducted. The pilot study gave a chance to the researchers to ensure the tool is measuring what it was intended to measure. The reliability of the assessment tool was conducted using Cronbach’s Alpha. The reliability tests the internal consistency of the assessment and ensures that test results provide consistent outcome in repeated measurements (Rahman, 2001). The accepted level of Cronbach’s alpha is 0.7 while 0.6 is also acceptable in exploratory studies (Saraph, et al., 1989). The internal consistency of the assessment principles/constructs was measured separately using SPSS. The limiting factor for acceptance used was an alpha level of 0.7. Table 2 presents the reliability test for the assessment tool. The assessment reliability test produced an alpha level of more than 0.7 for all principles/constructs of the assessment. The content and construct validity was also evaluated and measured. As far as the content validity, it was ensured that all items were based on an extensive literature search and previous studies as indicated in the literature review section. The constructs validity of the assessment was measured
