Suppose you are researching the eating habits of people your age.
a.) What sampling method could you use to find the percent of students in your grade who eat four servings of fruit and vegetables each day?
b.) What is an example of a survey question that does NOT have bias?
a.) A random sampling method could be used to find the percent of students in your grade who eat four servings of fruit and vegetables each day. This could involve randomly selecting a certain number of students from your grade and asking them about their eating habits.
b.) An example of a survey question that does not have bias could be: "How many servings of fruit and vegetables do you typically eat each day?" This question is straightforward and does not lead the participant to a specific answer.
