So I’m curious, how else could inconsistencies be created during the data collection phase?

I’m not actually sure myself.

With regard to this particular example, questions like "What distance from other trees determines whether or not a tree is categorized as alone or paired/grouped?‘’. Ask 100 people that question and you just might get 100 different answers. If there is no standardization to how data is collected and what determines the categorical outcome, the data will always have inconsistencies.

Example: The people collecting the data agree that any tree more than 15 meters away from any other will be considered alone, and any tree within 15 meters of another tree will be considered paired or grouped.

Unless every data point to be collected has this type of standardization inconsistencies will be introduced continuously, and near impossible to draw conclusions from the resulting data.
