There are four main levels: <strong>nominal, ordinal, interval,<\/strong> and <strong>ratio<\/strong>.<\/p>\n\n\n\n<p><strong>Nominal<\/strong> level is the lowest; it classifies data into distinct categories without any order. For example, <strong>marital status (i)<\/strong> only labels individuals (e.g., single, married) without implying any order.<\/p>\n\n\n\n<p><strong>Ordinal<\/strong> level data involves order or ranking but does not measure the exact difference between ranks. <strong>Tennis player rankings (b)<\/strong> and <strong>ratings of plays (f)<\/strong> fall into this category. While we know the order (e.g., excellent &gt; good), we don\u2019t know the precise difference between them.<\/p>\n\n\n\n<p><strong>Interval<\/strong> level has ordered categories with known, equal intervals between values, but no true zero point. <strong>Temperatures in refrigerators (d)<\/strong> are interval because 0\u00b0F does not mean &#8220;no temperature.&#8221; You can measure differences but not ratios.<\/p>\n\n\n\n<p><strong>Ratio<\/strong> level includes all properties of interval data, plus a meaningful zero point, which allows for comparison using multiplication or division. <strong>Weights (c), ages (h), times (g), horsepower (j), salaries (e),<\/strong> and <strong>number of pages (a)<\/strong> are all ratio data. A weight of 0 means no weight, and 20 lbs is twice as heavy as 10 lbs.<\/p>\n\n\n\n<p>In summary, <strong>nominal<\/strong> is categorical with no order, <strong>ordinal<\/strong> is ordered without meaningful intervals, <strong>interval<\/strong> has ordered and evenly spaced values but no true zero, and <strong>ratio<\/strong> has all of those properties including a true zero, enabling the most comprehensive statistical analysis.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/04\/image-94.png\" alt=\"\" class=\"wp-image-206886\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Classify each as nominal-level, ordinal-level, interval-level, or ratio-level measurement. a.
