VALIDITY AND RELIABILITY 3 VALIDITY AND RELIABILITY INTRODUCTION In Chapter 2, the study’s aims of exploring how objects can influence the level of construct validity of a Picture Vocabulary Test were discussed, and a review conducted of the literature on the various factors that play a role as to how the validity level can be influenced The two most important and fundamental characteristics of any measurement procedure are reliability and validity. Reliability and validity tells us whether a research being carried out studies what it is meant to study, and whether the measures used are consistent. These two principles are discussed below. Reliability Validity means that the results you find will be factually correct. It is often best to draw up your questions after you have finished your literature review (which is also most reliable!). You can then better judge which concepts are important, and use these concepts to draw up different questions (indicators)
