A Doctoral Dissertation conducted by Thomas M. Gravel, PhD, December 2006.

Excerpts of Data from Dissertation

Table 31 presents the Independent Samples t-Test. The Independent Sample t-test is the most commonly used method to evaluate the differences in means and between two groups. 121 participants completed the pre-workshop survey and 66 participants completed the post-workshop survey for a total of 187 surveys. The two surveys are identical with the exception that the post-workshop survey asked two open-ended questions that allowed the participant to provide a narrative if a change occurred as a result of the workshop in either administrative tasks performed or overall job satisfaction, (Gravel 59).
