For interval data, however, visualizations must focus on the equal intervals between points. Using a bar chart that does not start at zero can be misleading for interval data, as the visual length of the bars might imply a ratio that does not exist, thus misrepresenting the information to the audience.
Ratio Versus Interval Scale Logical Frameworks: Understanding the Distinction
Interval data, conversely, lacks this true zero; its zero point is arbitrary or defined by convention, meaning that ratios between numbers are not interpretable. Interval data, however, requires careful handling; calculating a mean is appropriate, but standardizing scores or using ratios can introduce mathematical fallacies that distort the reality of the measurement.
This allows for meaningful comparisons using multiplication and division. With ratio data, you are free to use geometric mean, coefficient of variation, and logarithmic transformations to explore relative growth and proportional change.

However, 20°C is not "twice as hot" as 10°C because the zero point is simply the freezing point of water, not an absence of thermal energy. Avoiding Critical Errors in Research and Business Misclassifying interval data as ratio data can lead to serious analytical errors.
