e-Articles (Chapter 11)
Here are some full-length research articles that illustrate the use of a one-way ANOVA to compare 3 or more sample means. To view any article, simply click on its title. (NOTE: No claim is made that these articles are perfect in all respects. By carefully reviewing them, you will hone your skills at being able both to decipher and to critique statistically-based research reports.)
In this study, a one-way ANOVA was used to compare 3 age-based subgroups of private practitioners regarding their beliefs about the potential harm of medicines. This same kind of ANOVA compared those same 3 groups in terms of their beliefs about the potential benefit of medicine, as well as the possible overuse of medicines. Similar one-way ANOVAs compared age-based subgroups of general practitioners and age-based subgroups of nurses. Another set of one-way ANOVAs compared experience-based subgroups of PPs, GPs, and nurses in terms of each dependent variable: harm, benefit, and overuse. See the next-to-last sentence in the 2nd paragraph of the "Statistical analysis" section, as well as the bottom portion of Table 2.
The means of three samples were compared in this study's one-way ANOVA. Results of this analysis are presented in an ANOVA summary table. See the last sentence of the "Data collection" portion of section 1, section 3, and Table 4.
Illustrates the use of a one-way ANOVA to compare the means of 3 samples. See the 1st 3 portions of the article's "Abstract" and the 1st 3 sentences in the 1st paragraph of "Results."
In this study, a one-way ANOVA was used to compare the means of 4 samples. This was done twice, once for each of the study's 2 dependent variables. See the next-to-last paragraph of the article's "Methods" section, the 2nd paragraph of the "Results" section, and Table 2.
