Validity is the extent to which the research provides a true picture of the social reality of those being studied. So in Nayak’s study the validity is based on whether he provided a full picture of the lives of the ‘Charvers’ and ‘Real Geordies’. Naka’s study is high in validity as the students who were interviewed would be comfortable in opening up as they are in an environment that they are used to. Also the observation that took place provides strong validity as the working class

Therefore‚ the study has population validity. As a result‚ we can apply the researcher’s findings to a large part of society. Furthermore‚ the study has cultural validity‚ because of its large sample. Therefore‚ it can be applied to people who are from vastly different backgrounds. Lastly‚ Fessler had a control group to compare results to. This was a group

The above factors increase the number of hits obtainable from each test‚ which affects positively on the validity of the questions. Whenever the test giver correctly identifies traits and state using the provided scale such as the Taylor Manifest Anxiety Scale‚ then the interpretation of the results is going to establish the real condition of the test taker

This is an appropriate design to establish causal connection between interventions and outcomes. The drawback of this design is a threat to internal validity which caused by contamination (bias) because the both infection control personal and ICU team were not blind to the study.

Experimental research is a systematic and scientific approach to research in which the researcher manipulates one or more variables‚ and controls and measures any change in other variables. Experimental Research is often used where: 1. There is time priority in a causal relationship (cause precedes effect) 2.

weight management study focused on URICA’s construct validity. In this study and many others‚ construct validity of the URICA has been supported through factor and cluster analyses demonstrating that the subscales are associated with different behavioral profiles or changes. Moreover‚ there is consistent evidence supporting the transtheoretical four-factor structure of the URICA. Furthermore‚ the measurement tool showed a good predictive validity‚ in foreseeing attendance and weight-loss this study
