In this chapter, we have reviewed the statistical analysis of unit vectors, as developed by Fisher . We have also introduced the bootstrap for unit vectors. Bootstrap procedures allow most of the useful statistical tests that are frequently performed on paleomagnetic data to be applied to non- Fisherian data. Many data sets are not Fisher distributed and the use of parametric tests can lead to erroneous conclusions. In contrast, use of bootstrap tests, when the data are Fisherian gives the same result — it just takes about 1,000 times longer to get it!
