MEASUREMENT SCALE
The four measurement scales, nominal, ordinal, interval, and ratio – differ, in that order, in the type and extent of statistical analysis that can be performed. Ratio-scaled data, because it is measured against an absolute zero point, supports the most powerful analysis, including inferential statistics, for experimental research.
For the following discussion, consider the following scenario: a pet store owner is interested in surveying its customers and learning more about customers’ pet ownership, attitudes toward various types of pets and pet products, basic demographic information, and spending habits.
Write one question for a survey that would meet the purpose of the research described in scenario provided above, using nominal, ordinal, interval, or ratio scaling. Then, choose an appropriate statistical method that could be used to analyze the data. Finally, describe how you would present this data graphically. Justify your choices.
