Between-Grid Analyses

Abstract

In this chapter, the basic analyses described in Chap. 5 are extended into comparisons across grids. These mostly person-centered analyses can be comparisons across different tasks or across measurement occasions as in a longitudinal study. The nature of these analyses often requires transforming the default stacked data format from the Gridware export into an unstacked format (see Box 6.1) and/or the exportation of individual cell measures (available only in version 1.1b, see Box 3.3). The fundamental question underlying these kinds of analyses can be stated as “how are the trajectories on two grids different from one another?” In this chapter, I will cover three ways that this has been done: profile analysis, intergrid distance scores, and cluster analysis.
