Question

Constant sum scales produce ratio scale data. true false

Answer 1

Constant sum scales produce ratio scale data. - False

Step-by-step explanation:

Constant sum scales, often used in survey research, require respondents to allocate a fixed total among different response options. While these scales provide ordinal data, indicating the order of preferences, they do not yield ratio scale data. Ratio scales possess a true zero point, allowing meaningful ratios and mathematical operations.

Constant sum scales lack this property as a zero allocation doesn't signify the absence of the measured attribute. Therefore, while useful for relative comparisons, these scales fall short in providing the level of measurement needed for precise quantitative analysis, such as calculating means or ratios with meaningful zero points.

Answer 2

No, constant sum scales do not produce ratio scale data. Ratio scale data has a starting point, meaningful differences, and calculable ratios.

Step-by-step explanation:

No, constant sum scales do not produce ratio scale data. This statement is false.

Ratio scale data is a type of measurement where the data has a starting point, the differences have meaning, and ratios between values can be calculated. However, constant sum scales do not have a starting point or allow for calculations of ratios.

For example, if we have a constant sum scale asking students to rate their level of agreement with statements on a scale of 1-10, we have interval scale data. Although we can order the ratings and understand the differences between them, we cannot calculate meaningful ratios (e.g., 10 is not twice as much as 5).
