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 biasedly or leadingly ask about eating habits?
One sampling method that could be used is stratified random sampling. This would involve dividing the entire population (all students in the grade) into smaller groups based on a relevant characteristic, such as gender or household income. A random sample of students could then be selected from each group to participate in the survey.
An example of an unbiased survey question about eating habits could be: "How many servings of fruits and vegetables do you typically consume each day?" This question does not suggest a specific number of servings or imply any judgement on the respondent's eating habits.
