Beyond the Answer
When measuring the heights of students, it's important to consider common units of height measurement. In the U.S., inches and feet are typically used, but in many parts of the world, centimeters or meters might be preferred. Each unit has its own importance depending on the context and audience—so pick the one that suits your needs best! For finding the average height accurately, the best method involves random selection. By randomly picking 35 students from the 9th grade and measuring their heights, you ensure that your sample is representative. Asking for volunteers can introduce bias, as those who volunteer may not reflect the average student's height, leading to skewed results in your findings!
