In order to decide about using composite or summated scale score for each question in the survey developed, it can be affirmed that the summated scale score can be used for the initial three questions. This might be owing to the reason that the results acquired from these questions will be quite limited and tends to be interrelated with one another. Though these three questions can be segregated into close-ended one, the summated scale score can be used in place of composite scale score. It is worth mentioning that the fourth and fifth questions are open-ended. It is projected that the answers or the responses of these questions will vary based on individual perspectives. Thus, the notion of composite scale score can be used in this situation. Specially mentioning, one of the functions of composite scale score scale can be ascertained as dealing with multiple data. Thus, for the questions ranging from 4-10, the applicability of composite scale score is justified (Spector, 2013).
The reliability, validity along with sensitivity are often regarded as the key tools of measuring varied sorts of errors that occur while conducting a survey. The notion of reliability mainly refers to the consistency or the dependability of the respondents towards research variables. Thus, it can be measured by evaluating the results of the research. The idea of validity mainly reflects the expected results of the research. With this concern, the validity can be measured by determining the effectiveness and most vitally the viability of the research results or responses. Finally, the perception of sensitivity denotes assessing the fractions of all the possibilities related to the completion of a particular research. It is in this circumstance the sensitivity can be duly measured in the form of ascertaining the information obtained from the respondents and appropriate interpretation of such data or information (Fayers & Machin, 2002).
