The 3.3V and 5V line of the Mushkin XP-800 AP are exceptionally stable. Even though the 12V line shows some fluctuations these are completely normal and no bad sign.
The ripple voltage is really big with 42.0 mV. If you look closer, you can see that this is mainly cause by a small number of spikes. Most of the ripple can be found within about 25 mV.

For easier comparison between power supplies we put the (normalized) line regulation standard deviation into graphs.
Standard deviation is a statistical term, which tells how far away from the average the measurements are. In other words it's the average of the average.
A large standard deviation indicates that the data points are far from the average and a small standard deviation indicates that they are close within the average.
So the smaller the standard deviation is, the better the line regulation.
