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?
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. Here's an example of how you could do it:
1. Obtain a list of all the students in your grade.
2. Randomly select a sample size that represents a portion of the total population (e.g., 10% or 20%).
3. Use a random number generator or another random selection method to choose the specific students from the list to be part of your sample.
4. Contact the selected students and ask them about their daily fruit and vegetable consumption.
Regarding an unbiased survey question, here's an example:
"What is the average number of servings of fruit and vegetables you consume daily?"
This question does not include any biased words or assumptions. It simply asks for factual information without inferring any specific answer.
To find the percent of students in your grade who eat five servings of fruit and vegetables each day, you could use a sampling method called stratified random sampling. Here's how you could do it:
1. Define your population: Identify all the students in your grade.
2. Create strata: Divide the population into different groups or strata based on relevant criteria. For example, you could divide students into male and female, or by different age groups within your grade.
3. Determine sample size: Determine the total number of students you want to include in your survey. This could be a random sample or a set number, based on your available resources.
4. Randomly select participants: Use a random selection method (such as a random number generator) to select the desired number of students from each stratum. Ensure that the selection is representative of the overall population in your grade.
5. Conduct survey: Ask the selected students the survey question regarding their daily consumption of five servings of fruit and vegetables.
6. Analyze data: Calculate the percent of students who consume five servings of fruit and vegetables each day by dividing the number of students who meet the criteria by the total number of participants.
Now, let's move on to creating an example of a survey question that does not have bias. Bias refers to any influence that can cause the question to have a preferred or distorted response. Here's an example of an unbiased survey question for your research:
"How many servings of fruits and vegetables do you consume on an average day?"
This question is straightforward and does not lead the participants towards a specific response. It allows the participants to provide their own truthful answer without any external influence or judgment.
First of all, you need to specifically define what you mean by "fruit and vegetables" and what constitutes a "serving." For example, does apple/orange/grape Juice qualify? If so, how much drink qualifies as a serving? How many grapes make up a serving?
Once defined:
"How many servings of fruit and vegetables do you have on an average day? Circle best estimate.
