Final answer:
Connectivity bias refers to how the presence or absence of channels influences spatial interaction, with well-connected areas likely engaging in higher levels of such interactions.
Step-by-step explanation:
In connectivity bias, the presence or absence of channels affects the likelihood of spatial interaction. This refers to the degree to which different locations are linked with one another through any form of transport or communication network. Connectivity influence factors such as the flow of information, goods, services, and people. A well-connected area is likely to engage in higher levels of interaction due to easier and more numerous channels facilitating these exchanges. On the other hand, the absence of such channels can hinder or limit the extents of spatial interaction.
