A series of MA plots.

A standard assumption in microarray experiments is that few genes should exhibit a change in expression, meaning that most points on the y axis should be close to zero (0) and the spline should be relatively flat. In this example, the points are scattered, indicating that data normalization is needed.

See MA Plot for more details about these plots.
