This is a measurement of height, which can take any value within a range and is not restricted to whole numbers. Height is a continuous variable<\/strong>, meaning it can be any value within a given range (e.g., 165.1 cm, 165.01 cm, etc.). Continuous variables can take an infinite number of values within a certain range.<\/li>\n\n\n\n
This is a count of something\u2014the number of sisters Jerwin has<\/strong>. The number of sisters is a specific, countable value (in this case, three), and it cannot be a fraction or decimal. Thus, it is a discrete random variable<\/strong> because it involves counting distinct occurrences (sisters), which can only take integer values.<\/li>\n\n\n\n
Weight is a measurement, and similar to height, it is a continuous variable<\/strong>. Jerwin could weigh 68.1 kilograms, 68.01 kilograms, or any other value within a range. Continuous variables can take an infinite number of values within their range.<\/li>\n\n\n\n
The distance Jerwin ran is a continuous variable<\/strong> because distance can be measured with great precision and could theoretically take any value within a range. For example, Jerwin could have run 500.5 meters, 500.02 meters, etc.<\/li>\n<\/ol>\n\n\n\nConclusion:<\/h3>\n\n\n\n
