Cheryl wants to find the number of hours seventh-graders do homework each week. There are 297 boys and girls in seventh grade. If Cheryl randomly surveyed 50 girls in the entire school to find the number of hours seventh-graders do homework each week, describe why she would get a biased sample.
Which of the following did you include in your response? Select all that apply. Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample. The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population. The results would not be a representative sample of the population.
Which statement(s) describe her sampling method? Check all that apply.
Which gives the best definition of a representative sample?
Write three to four sentences.
To create a valid sample, first obtain a complete list of all eighth-grade music students to identify the entire population. Use a random number generator or a similar method to select a specific number of students from this list. This ensuring that every student has an equal chance of being chosen, which helps avoid bias and produces results that accurately represent the group.
