the best example of the use of random sampling to determine who will be elected as your school president would involve
a. asking each student in your class whom he or she would vote for
b. asking one student in each classroom whom he or she would vote for
c. picking out a specific number of students as they leave the school, and asking whom they would vote for
d. asking every seventh student on an alphabetized list of all students whom they would vote for
i think its d
a is no good because the other classes do not know you as well, for better or worse.
b is much better but some classes may be much bigger than others and you are counting all equally.
c can be biased by who is not at school that day because of the flu affecting 11th grade football players.
d That sounds like a pretty good way.
asking every seventh student on an alphabetized list of all students whom they would vote for.
the answer is D
To determine the best example of the use of random sampling to determine who will be elected as your school president, let's analyze each option:
a. Asking each student in your class whom he or she would vote for: This approach does not involve random sampling but instead surveys the entire class. It does not represent the entire student population, so this option is not the best example.
b. Asking one student in each classroom whom he or she would vote for: This option involves selecting one student from each classroom. While it uses sampling, it may not be random unless the selection is done randomly. If the selection is done systematically (e.g., choosing the first student in alphabetical order), it may introduce bias. Therefore, this option may not be the best example either.
c. Picking out a specific number of students as they leave the school, and asking whom they would vote for: This option involves randomly selecting a specific number of students as they leave the school. Random sampling is employed here, ensuring that each student has an equal chance of being selected. This would be a good example of the use of random sampling.
d. Asking every seventh student on an alphabetized list of all students whom they would vote for: This option involves selecting every seventh student on an alphabetized list of all students. Although every student has a specific chance of being selected due to the systematic approach, it may not be considered truly random. Systematic sampling can introduce biases, especially if there are patterns in the alphabetized list. Therefore, this option may not be the best example of random sampling.
Based on the explanations above, the best example of the use of random sampling to determine who will be elected as your school president would be option c: picking out a specific number of students as they leave the school and asking whom they would vote for.
