ORDER YOUR PAPER AT WRITTASK.COM
What are comparative and non-comparative scales? Why might each type be used?
Among the four basic levels of scales, which one provides the researcher the most precise information, and why?

SAMPLE SOLUTION

Data Collection

Data collection is an important step in any statistical measurement. When the collected data is accurate, the analysis process will be easier and more meaningful results will ORDER YOUR PAPER AT WRITTASK.COM nature of the research; whether qualitative or quantitative, when data obtained is accurate, the validity and integrity of the results will be feasible. This task looks at the different aspects of data collection and statistical measurement.

Definition of Measurement and Construct and their Importance

Constructs can be defined as broad concepts or topics that can be subjects of ORDER YOUR PAPER AT WRITTASK.COM have meaning when interpreted theoretically or can exist in abstract form, which implies; they don’t have to be directly ORDER YOUR PAPER AT WRITTASK.COM is converted in a measurable form, they change to being called variables. Measurement, on the other hand, is defined as the process of assigning numbers to a given variable to make it more ORDER YOUR PAPER AT WRITTASK.COM concepts are important in that they help understand the nature of data that one is dealing with. They also help identify the data collection method that the researcher can use to improve data reliability.

Similarities and Differences between the Different Primary Scales of Measurement

There are four measurement scales in statistics; nominal, ordinal, interval and then ratio scale. Both the nominal and ordinal levels measure ORDER YOUR PAPER AT WRITTASK.COM to interval data, although, for an interval scale, there is a definite ordering and a difference between data. Furthermore, unlike the interval scale, which doesn’t have a zero starting point, the ratio scale has a zero as the starting point (Mergler, 2017).

How Scales Are Developed There are a lot of statistical, theoretical and methodological competencies that go into scale development which is a process to develop a reliable, valid measure of a given construct. The aim is to assess a given attribute ORDER YOUR PAPER AT WRITTASK.COM in scale development is to define the construct by specifying the domain, what is to be included and what is to be excluded. This step is key as it is important to ensure that it was intended to be measured is the one to be ORDER YOUR PAPER AT WRITTASK.COM is to generate the item which has to be 3 to 4 times higher than the final scale. The third step is to consider the content ORDER YOUR PAPER AT WRITTASK.COM is achieved by undertaking the initial screening of items, considering the applicability of the item to every dimension and the representativeness of the items…
