After publication of this article, the authors determined they were incorrect in the application of the Bonferroni correction and inadvertently applied it by level rather than tests conducted. In reviewing the SPSS output files, they discovered that the Bonferroni correction was already applied as part of the ANOVA BWW analysis. Hence, they did not need to apply a manual adjustment for multiple comparisons to the ANOVA BWW as is reported in the article. The changes to the critical alphas do not change reporting of the results.

In the Data analysis subsection of the Materials and methods, there is an error in the last sentence of the second paragraph. The correct sentence is: A Bonferroni correction was applied within SPSS for the ANOVA BWW analysis, and critical alpha set at 0.05.

In the Data analysis subsection of the Materials and methods, the authors do not report the critical alpha for the Welch one-way ANOVAs. The authors provide the following additional information: For the Welch one-way ANOVAs, a Bonferroni correction was applied as 0.05/6 as 6 one-way Welch ANOVAs were conducted. The critical alpha for the Welch one-way ANOVAs was set at 0.0083.

In the Data analysis subsection of the Materials and methods, the Bonferroni correction for the Games-Howell post-hoc analyses should be reported as 0.05/30 as there were 30 pairwise comparisons conducted for each Welch one-way ANOVA. There is an error in the last sentence of the third paragraph. The correct sentence is: Critical alpha was initially set at 0.05, then corrected to a Bonferroni-adjusted alpha level of 0.00167.

Three symbols denoting a significant difference are missing from the first two rows of Table 1. Please see the correct Table 1 here.
