Figure 1
The diagram is divided into four rectangular quadrants arranged in a two-by-two grid. The top left quadrant is labeled “Influential”, the top right quadrant is labeled “Key”, the bottom left quadrant is labeled “Excluded”, and the bottom right quadrant is labeled “Dependent”. At the center, overlapping the intersection of the four quadrants, a smaller rounded rectangle is labeled “Adjustment”. A vertical double-headed arrow runs through the center from top to bottom. A horizontal double-headed arrow runs through the center from left to right. The arrows intersect at the central “Adjustment” label.Influence-dependent chart. Source: Godet (1994)
