Aim: Spatial sampling bias (SSB) is a feature of opportunistically sampled species records. Species distribution models (SDMs) built using these data (i.e. presence-background models) can produce ...

With systematic sampling you can then select the points to monitor but this can introduce bias. Random sampling eliminates bias by generating the points randomly. Now you need sampling tools.

Although it is widely known that there are problems with data quality in terms of missing interactions and false positives 20, issues related to sampling bias are less well understood. Here ...

If you are using the wrong kind of sampling method for your experiment, this can lead to biased results. Sampling of the area you are studying must be random. It must show no bias – for instance ...
