Final answer:
Graphs are especially effective for making spatial judgements, as they visually convey patterns and relationships, which is not as easily discernible from tables.
Step-by-step explanation:
Graphs are more effective than tables for certain tasks, specifically when it comes to visualization of data. One of the primary applications of graphs is to express equations visually and to display statistics or data. This allows for the condensation of detailed numerical information into a visual form, where relationships and numerical patterns become evident more quickly and intuitively compared to sifting through tables full of numbers.
For the question asked, graphs are more effective than tables for 1) Spatial judgements because they allow the viewer to assess spatial relationships and patterns at a glance. On the other hand, for reading precise values, tables are often more effective than graphs because they provide exact numbers rather than approximations that visual interpretations of a graph tend to offer. So, the correct answer here would be 1) Spatial judgements.
