However, they can also potentially introduce biases, such as coverage biases and measurement error. The current study compares the relative merits of two survey distribution and completion modes: email recruitment with internet completion; and…

This paper discussed methods currently under study for use with multiple-response data. Besides using Bonferroni inequality methods to control type one error rate over a set of inferences involving multiple response data, a recently proposed methodology of plotting the p-values resulting from multiple significance tests was explored. Proficiency…
