Figure 8.3 A graphical comparison of two smartphone designs according to whether they are perceived as modern or dated

The graph in Figure 8.3 shows how the two smartphone designs varied according to the respondents’ perceptions of how modern the design is. This graphical notation shows clearly how the two designs compare.

Data logs that capture users’ interactions with a system can also be analyzed and represented graphically, thus helping to identify patterns in behavior. Also, more sophisticated manipulations and graphical images can be used to highlight patterns in collected data. Box 8.3 describes how data logs of an online computer game were used to identify patterns of interactions. This example also shows how observational data can be used to interpret quantitative data.

The examples given in this section have largely focused on data sets which have more than 10 records (i.e. respondents or interviewees). If only a small number of records are collected, then it may be more important to analyze the individual records in more depth than to identify trends. In this case, tabulating the data for ease of presentation may be sufficient.
