Research Problems REDUX

In reviewing Practical Research by Leedy and Ormrod (2005, 9th edition), I think (hope!) I see some light regarding the research problems.

1. The main research problem is in the Purpose of the Study statement.
2. The other four research problems are simply subproblems of the main problem.

Leedy and Ormrod say this about subproblems (pages 51 and 52).  Each subproblem:

1. Should be a completely researchable unit (hence, why a subproblem is really a research problem).
2. Must be clearly tied to the interpretation of the data.

Further,

1. The subproblems must add up to the totality of the problem.
2. Subproblems should be small in number (as per the requirements of the proposal, no more than four).

Leedy and Ormrod also suggest the use of "Brainstorming Software" to identify subproblems.  They have an illustration of output on page 72.  There, the software they use is something called Inspiration.  I found it here:  http://www.inspiration.com/Inspiration

It's pretty cool - and inexpensive (US$40).  I downloaded it this morning.  My weekend plans are set, apparently.
