Validity and reliability are two important factors to consider when developing and testing any instrument (e.g., content assessment test, questionnaire) for use in a study. OR An instrument that is valid, but not reliable? Reliability esti- mates evaluate the stability of measures, internal consistency of measurement instruments, and interrater reliability of instrument scores. The previous slides about reliability and validity refer to instrument development. This type of reliability often helps researchers interpret data and predict the value of scores and the limits of the relationship … Reliability and Validity Today’s Objectives Understand the difference between reliability and validity Understand how to develop valid indicators of a concept Reliability and Validity Reliability Validity • How accurate or • Does the concept consistent is … Reliability & Validity Which is plausible? In Quantitative research, reliability refers to consistency of certain measurements, and validity – to whether these measurements “measure what they are supposed to measure”. Reliability estimates evaluate the stability of measures, internal consistency of measurement instruments, and interrater reliability of instrument scores. But how do researchers know that the scores actually represent the characteristic, especially when it is a construct like intelligence, self-esteem, depression, or working memory capacity? �� / � 0 � �0 �D A r i a l n g s �� �� �/%� � ��0 � :A 0 � " �D T a h o m a g s �� �� �/%� � ��0 � :A 0 � " �D T i m e s N e w R o m a n � � ��0 � :A 0 � 0 �D W i n g d i n g s R o m a n � � ��0 � :A 0 � � VALIDITY AND RELIABILITY 3 VALIDITY AND RELIABILITY 3.1 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 … : are the Statistical conclusions well-grounded minimum reliability of.70 is required for attitude instruments with PowerShow.com instruments used a!
