Questions and Answers

What characterizes an interval scale that differentiates it from an ordinal scale?

It has meaningful distances between values. (correct)

It lacks a defined unit of measurement.

It provides categorical data with no inherent order.

It only measures qualitative differences.

Why does a score of 0 on an interval scale not signify the absence of the property being measured?

Because scores can only range from 1 to infinity.

Because zero is a universal standard across all scales.

Because the scale can contain arbitrary units of measurement. (correct)

Because interval scales measure only qualitative data.

Which of the following examples illustrates an interval scale?

Categorizing a survey response into positive and negative.

Ranking individuals from first to last in a race.

Measuring temperature in Fahrenheit. (correct)

Types of Scales

Recap of scales
Likert scale (specific type discussed further)

Marketing Research Process

Step 1: Map a business problem into a marketing problem.
Step 2: Translate the marketing problem into a research methodology.
Step 3: Design the research instrument.
Step 4: Devise a sampling plan.
Step 5: Collect data & clean data.
Step 6: Analyze data into information & report information.

Scale: (3) Interval Scale

Ordinal scales do not imply distance between evaluations.
Interval scales do imply distance between evaluations because they are based on a unit of measurement.
Examples include temperature (Fahrenheit or Celsius), standardized exam scores (like GMAT scores).
The value of '0' in an interval scale doesn't mean nothingness or a vacuum.
A Gold Medalist is not a larger value than a person without a medal. They are simply more successful in the sport/event
Cannot multiply or divide interval data or take ratios.
Statistical techniques such as percentages, mode, percentile, quartile, median, minimum, maximum, range, mean and standard deviation can be used.

Scale: (4) Ratio Scale

Ratio data is derived a ratio scale and inherits characteristics from nominal, ordinal, and interval scales.
Includes numerical values that can have a meaningful "0" value which indicates nothingness
Examples include age and weight.
Can multiply or divide ratio data/take ratios.

Review of Scales

Nominal: Labels, no numerical value (e.g., colors, brands)
Ordinal: Rank orderings, distance between values meaningless (e.g., ratings, rankings)
Interval: Unit of measurement but no true zero (e.g., temperature, standardized tests)
Ratio: Unit of measurement and true zero (e.g., height, weight)

Likert Scale

A type of ordinal scale.
Often presented as a questionnaire with rating options (e.g., strongly disagree to strongly agree).
Data from a Likert scale is often treated as interval data (even though it's technically ordinal).
Researchers need to explicitly identify it as a Likert scale for readers to understand its treatment from an ordinal scale to an interval scale.
