Controlling for Judge Differences in the Measurement of Public Speaking Ability.
Tatum, Donna Surges
Understanding the behavior of those evaluating a speech is important for a complete understanding of the public communication process. Ratings of public speaking were submitted to a Rasch analysis to determine whether objective measurement can create and maintain a standard of speech evaluation. Data used were 1,022 ratings of 168 speeches given by 34 public speaking students at Roosevelt University in Chicago (Illinois) in 2 successive years. Speeches were evaluated by four independent raters and student speakers acting as raters. Raters used an 83-item list of components of a good speech completed by 5 speech teachers. The FACETS computer program of J. M. Linacre provided the means of performing the Rasch analysis. Data do not reveal a pattern to rater severity. Independent raters and teachers were no tougher in their judgments than were speakers. A speaker's ability was not related to how tough he or she was as a rater. Results do indicate that objective measurement can create and maintain a standard of speech evaluation. Three tables and three figures illustrate the study. There is a 14-item list of references.
