If you wanted to find the mean height of students in an elementary school, which group would provide the most accurate sample?

A. Two students from each classroom in the school
B. All the boys from the school
C. All the girls from the school
D. Two students from each third-grade classroom


Sagot :

Final answer:

Group D - two students from each third-grade classroom is the most accurate sample for finding the mean height of students in an elementary school, providing a representative random sample.


Explanation:

In this scenario, group D - two students from each third-grade classroom, would provide the most accurate sample for finding the mean height of students in an elementary school.

By selecting students from each third-grade classroom, you are ensuring a representative sample that includes a mix of heights from different classes, rather than biased samples like choosing only boys or girls.

This method follows the principle of random sampling, which improves the accuracy of the mean height estimation for the entire elementary school's student population.
