Theoretical directed network. This theoretical network displays the bi-directional nature of data collection. Each circle, or node/individual, is labeled with a letter-#, where the number indicates the individual’s out-degree value. For example, A-2 indicates person A gave advice to two other individuals. All gray arrows indicate the node of origin reported giving advice to the end node (e.g., C reported giving advice to D). All red arrows indicate the end node reported receiving advice from the origin node (e.g., A reported receiving advice from H). Individuals received a tally for their out-degree when they reported giving advice to an individual and when an individual reported receiving advice from them, which is considered bi-directional data
