-------------
Nonprofit organizations (NPOs) have a long and varied history in American society. According to the Annie E. Casey Foundation (2005) the results of a Nonprofit Executive Leadership and Transitions Survey commissioned in 2004 indicate large numbers of today's nonprofit leaders, members of the large Baby Boom generation will seek new roles, new careers, or retire. The transition of executives over the next five years will become an increasingly significant issue in the nonprofit sector (Annie E. Casey Foundation, 2005).

Quasi-experimental design:
What is the impact of transformational leadership have on job satisfaction?
Quasi-experimental design involves selecting groups, upon which a variable is tested, without any random pre-selection processes. For example, to perform an educational experiment, employees might be arbitrarily divided by alphabetical selection. The division is often convenient. After this selection, the experiment proceeds in a very similar way to any other experiment, with a variable being compared between different groups, or over a period of time i.e. employee satisfaction. (http://www.experiment-resources.com/quasi-experimental-design.html#ixzz0d6JuA7Ab)
A quasi-experimental design is like an experimental design but lacks the key ingredient -- random assignment as well as no control group. Regarding internal validity, the Quasi-experimental design is inferior to randomized experiments. (http://www.socialresearchmethods.net/kb/quasiexp.php)
? Whilst regarded as unscientific and unreliable, by physical and biological scientists, the method is, nevertheless, a very useful method for measuring social variables.
? The inherent weaknesses in the methodology do not undermine the validity of the data, as long as they are recognized and allowed for during the whole experimental process.
? Quasi experiments resemble quantitative and qualitative experiments, but lack random ...
