Rules of Thumb from the Literature on Research and Evaluation.
Lai, Morris K.
Practical advice on frequently asked questions dealing with research and evaluation methodology is presented as rules of thumb, with citations to the author's sources. A statement in the literature is considered a rule of thumb if it meets one of the following criteria: (1) it is specifically called a rule of thumb; (2) it contains numbers in place of algebraic symbols; or (3) it contains a reference to previous successes using a particular level. The rules included here deal with article title, budgeting for research staff, test difficulty and discrimination, distribution, significance, Fisher test, reliability of gain scores, interrater reliability, item construction, testing time, response rate, observation, sample size, sampling, skewness, test wiseness, test-retest reliability, and test revision.
