Table 2. Mean and standard deviation of times spent on task.
Note that the task numbering here (1–12) is for convenience of reporting, and it does not express the task types as introduced in the experiment design section. To make the link, the ‘tracing method’ column is important (i.e., experimental tasks are repeated based on tracing method per shape type).
