Measurement Scales/Business Research

timer Asked: Oct 26th, 2015

Question description

Construct 4 additional pages for your course project (title page not counted):

Decide which measurement scale will work the best for your project and the criteria needed for effective evaluation using this scale, including accounting for errors. Select at least two measurement errors that may be a concern using the chosen scale and construct how the project will account for them. Create these pages:

  • Background Material
  • Limitations

·  In this week's assignment you will want to write on any background information that is relevant to your research. This would be based on your company. The next part of the assignment is for you to state the exact measurement scales you are going to utilize. (The Measurement Scales are listed below) Then you will want to explain why you would want to utilize this scale(s) and then possible limitations you may have (need to use sample size due to budget constraints). Once you have explained your scale(s) you will want to explain possible errors that may occur. What will you do to account for these possible errors?

·  Nominal comes from the Latin root nomen, meaning name. A nominal scale only identifies (or "names") the variable. A good example is asking participants if they are "male" or "female".

·  The ordinal scale measures the nominal scale plus an order. An example is a question that asks for an opinion and gives choices such as "completely agree", "mostly agree", "neutral", "mostly disagree", "completely disagree".

·  An "interval" is the space between two things. Interval scales describe nominal and ordinal values plus the amount between each item. A good example is found on a thermometer. The temperature is scaled at regular intervals, whether one degree or ten degrees apart.

·  A ratio uses the qualities of nominal, ordinal, and interval scales, but also includes an absolute zero (a point where none of the quality being measured exists).Variables like height and weight are examples of ratio variables. Temperature cannot be a ratio variable because a temperature of 0 does not mean "no temperature".
