To measure the average height of students, you'd typically use units like feet or centimeters, as these provide a clear and standardized way to express human height. For instance, centimeters (cm) might be more common in many countries, while feet (ft) is often used in the United States. Inches could also be used, but feet and centimeters generally provide a more streamlined measurement for average height on larger scales. When selecting a method to find the average height, the best approach is to randomly pick 20 students from the 11th grade and measure their heights. This method ensures that you get a representative sample of the entire grade rather than relying on self-reported heights or volunteers, which could introduce bias. Random sampling minimizes the chance of skewed data, leading to a more accurate average representation.
