A **funnel plot is a graph*** designed to check for the existence of publication bias; funnel plots are commonly used in ***systematic reviews and meta-analyses***. In the absence of publication bias, it assumes that studies with high precision will be plotted near the average, and studies with low precision will be spread evenly on both sides of the average, creating a roughly*** funnel-shaped distribution***. Deviation from this shape can indicate publication bias.

To plot is to graph (not some conspiracy).
