Question

i need a good survey question to ask 44 people (all 18 years of age or older) that requires a numerical answer on an interval or ratio scale of measurement.

Answer 1

Interval Scale is defined as a numerical scale where the order of the variables is known as well as the difference between these variables. Variables which have familiar, constant and computable differences are classified using the Interval scale.

The following questions fall under the Interval Scale category:

• What is your family income?
• What is the temperature in your city?

Ratio Scale is defined as a variable measurement scale that not only produces the order of variables but also makes the difference between variables known along with information on the value of true zero. It is calculated by assuming that the variables have an option for zero, the difference between the two variables is the same and there is a specific order between the options.

The following questions fall under the Ratio Scale category:

What is your current height?

• Less than 5 feet.
• 5 feet 1 inch – 5 feet 5 inches
• 5 feet 6 inches- 6 feet
• More than 6 feet

What is your weight in kilograms?

• Less than 50 kilograms
• 51- 70 kilograms
• 71- 90 kilograms
• 91-110 kilograms
• More than 110 kilograms
