It is possible to describe what factor analysis does in analogous terms – that is, as an attempt to fit factors which explain the greatest amount of joint variance (i.e., shared variance) between X and Y (there is no dependent-predictor relationship between variables in factor analysis), and thus the overall variance in each. One way of doing this is by rotating the axes of the graph to the point of best fit, as shown in Figure 9.2.
