The interval scale is defined as the 3rd quantitative level of measurement where the difference between 2 variables is meaningful. Let's explore!
Is temperature an example of interval? An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include: temperature (Farenheit), temperature (Celcius), pH, SAT score (200-800), credit score (300-850). ...
2.4.4The ratio scale A ratio scale has the same properties as theinterval scaleexcept that the zero point cannot be chosen but is defined by nature. Examples of ratio-scaled variables are absolute temperature, weight, the concentration of glucose in the blood. ...
2. Ordinal variables: These not only categorize but also allow for an order or ranking among the categories. Education levels or Likert scale responses (where respondents rate their agreement on a statement) are examples of ordinal variables. The order of responses is significant, but ...
There is no true zero on an interval scale, which is what distinguishes it from a ratio scale. On an interval scale, zero is an arbitrary point, not a complete absence of the variable. Common examples of interval scales include standardized tests, such as the SAT, and psychological inventori...

Here is the scale of C major, showing each interval type when the lowest note is the tonic: In all major scales, the unison, fourth, fifth and octave arePERFECTintervals. All the other intervals areMAJOR. Here are some examples of intervals from other major keys: ...
Likert-type questions (e.g., very dissatisfied to very satisfied) Interval levelExamples of interval scales You can categorize, rank, and infer equal intervals between neighboring data points, but there is no true zero point. The difference between any two adjacent temperatures is the same: one...
Interval Data Examples 1. One can measure time during the day using a 12-hour clock, this is a good example of interval data. Time in a 12-hour format is a rotational measure that keeps restarting from zero at set periodicity. These numbers are on an interval scale as the distance betwe...
In user experience, the System Usability Scale (SUS) is one example of interval data. SUS (described in detail in Chapter 5) is based on self-reported data from a series of questions about the overall usability of any system. Scores range from 0 to 100, with a higher SUS score indicatin...
