CHAPTER 5 1 INTRODUCTION

This chapter covers sample and data analysis methods that are used for investigative monitoring. Often, the standard
methods leading to status classification, as described in Chapters 2 and 3 are suitable, but sometimes other methods are
more appropriate. An introduction to investigative monitoring and its aims are described in Chapter 4.
