The web is rapidly becoming the most popular way to collect data from university students. It is important to understand the response traits of this population – especially any differences that may exist within sub-populations. Using data collected from the 2007 Healthy Minds Study, a survey of 13,000 graduate and undergraduate students from 12 universities, this paper explores the difference in response behavior between graduate and undergraduate students. We will examine the response behavior of these two student groups by comparing several survey environment variables. The survey environment variables of interest include; the length of time respondents spend in the survey, the time of day the completed survey was submitted, the browser used to submit the survey, the number of logins required before the survey was submitted and the time it takes to submit after the initial contact. Where appropriate, we will also examine differences in measures of survey quality – such as item missing data rates and completion rates. Understanding these variables in the context of student life is important in creating and administering effective web-based surveys and contact protocols to university students. Each of the variables will be examined for the population group as a whole and then broken down by graduate and undergraduate students allowing for independent conclusions for and comparisons between each group. Once these administrative variables have been examined, more informed decisions can be made when deciding how and when web-based surveys will be administered on college campus.
