A Powerful Test of Likert-Type Item Polarity and Disagreement
Fri, April 9, 4:10 to 5:40pm EDT (4:10 to 5:40pm EDT), SIG Sessions, SIG-Survey Research in Education Paper and Symposium SessionsAbstract
The purpose of this paper is to provide a procedure for testing the polarity and disagreement of single Likert-type items, and to illustrate, given a strong effect, how powerful the test is. New alternatives for testing disagreement and effect size estimates are also offered. As the necessary multinomial calculations are intensive, a spreadsheet for calculation is also provided. Small sample size examples are offered.
