The levels of measurement are <strong>nominal, ordinal, interval,<\/strong> and <strong>ratio<\/strong>, each with increasing mathematical meaning.<\/p>\n\n\n\n<p>In this case, the data set refers to the <strong>number of milligrams of tar in 95 cigarettes<\/strong>, which is a <strong>quantitative<\/strong> measurement. Let\u2019s break down the levels of measurement to see which one fits:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Nominal<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Definition:<\/strong> Categories without a specific order or numerical value (e.g., colors, names, brands).<\/li>\n\n\n\n<li><strong>Example:<\/strong> Types of cigarette brands.<\/li>\n\n\n\n<li><strong>Why Not Nominal?<\/strong> Milligrams of tar is numerical and measurable, not just a name or label.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Ordinal<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Definition:<\/strong> Categories with a specific order but unequal or unknown differences between them.<\/li>\n\n\n\n<li><strong>Example:<\/strong> Ranking cigarettes as low, medium, or high in tar content.<\/li>\n\n\n\n<li><strong>Why Not Ordinal?<\/strong> The data are exact measurements (milligrams), not ranks or levels.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3.
