Suppose you are researching the eating habits of people your age. What sampling method could you use to find the
percent of students in your grade who eat five servings of fruit and vegetables each day? What is an example of a
survey question that does not have bias?
One sampling method that could be used to find the percent of students in your grade who eat five servings of fruit and vegetables each day is stratified random sampling. This method would involve dividing the population of students in your grade into different strata (e.g. males and females, different classes), and then randomly selecting a proportionate number of students from each stratum to participate in the survey.
An example of a survey question that does not have bias could be: "How many servings of fruits and vegetables do you typically eat in a day?" This question is straightforward and does not lead the respondent to answer in a particular way.
