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?
I have the second part of the question, but I am not sure what sampling method could be used. My new sampling question would be"What do you eat on a daily basis?" and it would ask every student in the first period.
I need help with the first part of the question, not the second part. What type of sampling method is this?
To find the percent of students in your grade who eat five servings of fruit and vegetables each day, you can use a random sampling method. Here's how you can proceed:
1. Define the population: Determine the specific grade you want to study, such as 12th grade students or all students in your school.
2. Obtain a list of all students: Obtain a comprehensive list of all students in the chosen grade. This can be acquired from your school administration or through relevant records.
3. Randomly select a sample: Implement a random sampling technique to select a representative sample from the list of students. One way to do this is by assigning each student a number and using a random number generator to choose a predetermined sample size. Another method is to use a random number table or a specialized computer software.
4. Administer the survey: Provide the selected students with the survey questionnaire you have prepared. Make sure the questionnaire includes questions about their eating habits, specifically about the number of servings of fruits and vegetables they consume each day.
5. Analyze the data: Once you have collected the responses, calculate the percentage of students who report consuming five or more servings of fruit and vegetables daily based on the total number of respondents.
Regarding your survey question, "What do you eat on a daily basis?" can be a good starting point to gather information about eating habits. However, to minimize bias, it is essential to frame the question in an unbiased manner. Here's an example: "Please list all the food items you typically consume in a day, including fruits and vegetables." This open-ended question allows participants to freely express their eating habits without leading or influencing their responses.
To find the percent of students in your grade who eat five servings of fruit and vegetables each day, you could use a random sampling method. Randomly selecting a representative sample of students from your grade would help ensure that the results are not biased and are reflective of the entire population.
As for the survey question, "What do you eat on a daily basis?" is a suitable question that does not contain bias. It is broad enough to capture various food choices and does not imply any particular preference or judgment. Asking this question to every student in the first period would provide a comprehensive understanding of their eating habits.
