Figure 3
A funnel plot of standard error by Fisher's Z. The plot features dozens of data points represented by blue circles scattered within a triangular funnel shape. The x-axis represents Fisher's Z values ranging from negative 2 to positive 2, while the y-axis represents standard error values ranging from 0 to 0.2. The data points are concentrated around the center of the plot, forming a funnel-like pattern that widens as it moves away from the center. The plot includes a central reference line at Fisher's Z value of 0.5, with data points spread around this line. The plot indicates the relationship between standard error and Fisher's Z, showing how standard error varies with different Fisher's Z values. The funnel shape suggests the expected range of standard errors for given Fisher's Z values, with most data points falling within this range. All values are approximated.Funnel plot.
