If you know about a mistake or blunder, you can, at least in principle, fix the problem and eliminate the mistake. Some experimental error is intrinsic. While it can be minimized, it cannot be eliminated. A perfectly executed experiment. Determinate error is also called systematic error.
Indeterminate errors arise from uncertainties in a measurement as discussed above.
Indeterminate error is also called random error, or noise. Indeterminate error can be minimized but cannot be eliminated. Let's imagine that you weigh a calibration weight several times. You look more closely at the weight and discover there is a piece of tape stuck to it. All of the values fall near 10.0g, but some are a bit higher, some a bit lower, some differ from 10.0 by 0.1g, others differ by 0.2g.
