Measurement discipline deals with:
Measurement discipline is an important aspect of research and data collection in various fields. It involves the systematic identification, selection, and evaluation of objects and events, as well as the determination of appropriate measurement scales. The correct answer to the given question is option 'D' which states that measurement discipline deals with the identification of objects and events, selection of scale, and evaluation of dimension of measurement scale. Let's understand each aspect in detail:

Identification of objects and events:
Measurement discipline begins with the identification of objects and events that need to be measured or observed. This involves clearly defining the research question or objective and determining the specific variables or phenomena that will be studied. For example, in a study on customer satisfaction, the objects of measurement may include various aspects such as product quality, service responsiveness, and overall experience.

Selection of scale:
Once the objects and events are identified, the next step is to select an appropriate measurement scale. A measurement scale is a system or framework used to assign numbers or labels to the variables being measured. There are different types of measurement scales such as nominal, ordinal, interval, and ratio scales. The choice of scale depends on the nature of the variable and the level of measurement required. For example, a Likert scale can be used to measure attitudes or opinions, while a nominal scale can be used to categorize variables into distinct categories.

Evaluation of dimension of measurement scale:
In addition to selecting a scale, measurement discipline also involves evaluating the dimension or characteristics of the measurement scale. This includes determining the range, precision, and meaningfulness of the scale. For example, if a scale measures customer satisfaction on a scale of 1 to 10, the evaluation of the dimension would involve assessing whether the scale adequately captures the full range of satisfaction levels and whether the difference between a rating of 5 and 6 is meaningful.

In conclusion, measurement discipline is a systematic approach to the identification, selection, and evaluation of objects and events in research. It involves understanding the research question, selecting an appropriate scale, and assessing the dimension of the measurement scale. By following these principles, researchers can ensure that their measurements are accurate, reliable, and meaningful.
