A geographer may choose a Robinson projection for a reference map in a textbook because it provides a good balance between preserving shapes and distances on the map. The Robinson projection is a compromise projection, meaning that it sacrifices some accuracy in certain areas for a more visually pleasing and balanced overall representation of the Earth's surface. This can make it easier for students to understand and compare different regions and features on the map. Additionally, the Robinson projection has less distortion near the poles compared to other projections, which can be useful for showing a wide range of geographic data in a clear and comprehensible way.
