Each construct in the hypothesis (for example, 'specialisation of telemarketing representatives') must be capable of being measured; precisely how the insu•uments were designed to measure the constructs is described later in section 3. That is, operational definitions of the consü•ucts developed for hypotheses are not divulged until section 3, that is, the statistical form of a hypothesis involving null and alternative hypotheses about means,distributions or correlation coefficients, for example, is not presented until sections 3 and 4. Indeed, this distinction between hypotheses about constructs in section 2 and hypotheses about population statistics in section 3 can be confusing. Several students prefer to refer to section 2's hypotheses as propositions and resu•ict the term hypothesis to the associated and similarly numbered statistical forms developed in section 3 after operational definitions of identified in section 2, have been constructed.
