1-Dimensional Data Sets

5.1 Introduction

A 1-dimensional data set is a structure in which each of the constituent ele-

ments is measured and indexed along a single dimension. The 1-dimensional

data set, also known as a 1 -dimensional array, is the archetypical subject of

many foundational quantitative analytic techniques. For example, it is the

simplest type of data set on which to perform frequency analysis , a powerful

investigatory tool. Useful c leaning and filtering techniques can also be applied

to rid 1-dimensiona l data of misleading systematic errors. As usual, I’ll discuss

situations where these techniques are appropriate, as well as some
