Reliability refers to the consistency of the measurements or the degree to which an instrument measures the same with every use under the exact same conditions. Rigour, in quantitative studies, refers to the extent the researchers worked to enhance the quality of the study this is achieved through measurement of reliability and validity. These procedures help demonstrate the rigour and usefulness of the researcher’s work. As a way of measuring the likelihood of the researcher’s result being misleading, statisticians developed procedures for expressing the likelihoods and accuracy of the results. Quantitative research is the process of a systematic investigation, primarily using numerical techniques (statistical, mathematical or computational), to test hypothetical generalisations.
