The observer recorded the duration required to complete each graph, as well as the total duration to complete all three graphs. At this point the experimenter saved the current graph, deleted the participant's data, opened a new instance of Excel 2007, and instructed the participant to begin the next graph. The experimenter instructed participants to complete the three graphs in sequential order (i.e., reversal, multielement, and MBD), pausing after each graph was created. The experimenter instructed participants to use their technical article to create three graphs from the three hypothetical data sets they were provided. Participants were also asked to rank their overall level of experience with creating graphs of any type in both Microsoft Excel 20 on a 5-point Likert scale ranging from 1 ( no experience) to 5 ( regularly make graphs). Participants estimated the number of reversal, multielement, and MBD graphs they had created in the past with both software versions.
Participants in Group 2 received the technical article by Carr and Burkholder (1998), which contained instructions that were relevant for all of the software versions before Excel 2007.Īll participants completed a brief survey requesting demographic data and information regarding experience creating various types of single-subject design graphs in Microsoft Excel (both the 20 versions). Participants in Group 1 received the instructions presented later in this article on creating graphs in Excel 2007.
Participants were randomly assigned to one of two groups. Prior to the study, the experimenter provided each participant with a packet of materials that included instructions for completing the study, three sets of hypothetical data, and one of two technical articles that provided information for the creation of three single-subject design graphs (i.e., reversal, multielement, and multiple baseline designs ) in Microsoft Excel. monitor, keyboard, mouse, and Microsoft Excel 2007 software. Each room contained a Dell Dimension PC equipped with a 32-in. The study was conducted in three small rooms housed within a laboratory of a large midwestern university. All students had varying levels of experience creating single-subject design graphs in Microsoft Excel. Twenty-two graduate students (21 women, 1 man), recruited from a behavior analysis graduate program, participated in the study for extra course credit.
