when we carry out a science experiment, why do we find anomalous results?
what affect do anomalies have on the evidence?

Whenever you're doing an experiment, you are going to have errors and uncertainties. Often, these errors are small and don't have a very big effect on accuracy, which is why anomalous results are rare. A small amount of natural variation is to be expected. However, occasionally there might be a very big variation for a single result. This will generally be to do with human error. Try to think of different ways you might accidentally mess up a measurement.

For the second question, think about this. Whatever you're measuring, there's going to be a true value. If we've got lots of similar results and one massively different results, its likely that the similar results are close to the true value and thus the other result isn't. So what will happen if we factor in this obviously wrong result into our calculation?
