Cheat Sheet
- Nominal Scale Essentials -
Nominal measurement classifies data into distinct categories without any inherent order, such as gender or hair color. It's foundational in surveys and categorical analyses because you only count frequencies or use the mode as a measure of central tendency (OpenStax Statistics). Remember "name only" to recall it's all about labels, not quantities.
- Ordinal Scale Ordering -
Ordinal data provide a rank order - think customer satisfaction ratings or class standings - where distances between ranks aren't equal (University of California, Berkeley). You can determine which is higher or lower but can't compute meaningful differences like you would with interval data. A handy trick: "order first, measure later."
- Interval Scale Insights -
Interval scales feature equal intervals between values but lack a true zero point, examples include Celsius or Fahrenheit temperatures (National Weather Service). You can add and subtract values, but ratios don't make sense - 20°C is not twice as hot as 10°C. Recall "intervals intact, zero abstract."
- Ratio Scale Advantages -
Ratio scales have all the properties of interval scales plus an absolute zero, so you can add, subtract, multiply, and divide (Statistics Canada). Common examples are weight, height, and time measured from a true zero start. Think "ratio's real zero" to lock in that meaningful absence point.
- Mnemonic NOIR for Levels -
Use the acronym "NOIR" (Nominal, Ordinal, Interval, Ratio) as a memory aid, borrowed from classic statistics pedagogy (American Psychological Association). Placing the four levels in ascending order highlights increasing mathematical operations. Picture a painter's palette labeled NOIR to keep it vivid and memorable.
