=======================================================================

State the population of your study. You should be able to do this in one to three sentences. Include specific characteristics including age range, gender, location, and any other identifiers that are unique and relevant to your population. Justify why this is the best population for the study.

My target population is 1000 Americans in the United States ranging from the age 13 and up. I believe this is the best population to use for my study because obesity starts at an early age, and it is rapidly growing in the United States. The minimum age is set to 13 years of age which would include a parent consent. Some participants would need consent from a parent or guardian. Participants 18 years old and up has no requirement of consent considering they are legal.

EXAMPLE:

My target population is 1000 American residents residing in any state, ages 18 plus. I believe this is the best population to use for my study because I would like to focus on the attitudes of American residents towards GMOs specifically. The minimum age is set to 18 so that the participants can give their consent, and no other limitations are set on the population, to provide for varied and diverse population demographics.

Describe your sampling strategy. Write at least one paragraph describing your sampling strategy, how you would attempt to conduct your survey, and any potential issues that might affect your survey results. You should use one of the following techniques: random, stratified, cluster, systematic, or convenience. Your choice of strategy should be based on the purpose of your survey and your population. Explain why this is the best chosen sampling strategy.

The sampling strategy I would use is random sampling. Random sampling strategy would be very beneficial to this topic about obesity. This is the best-chosen sampling strategy because in this study females and males are being randomly picked from ages 13 and up. This voluntary participation matter because everyone is not comfortable about their weight.

EXAMPLE:

My sampling strategy is random sampling. Because about 95 percent of homes have a phone, I would follow the same reliable procedure that the Gallup poll surveyors do: a computer would be used to create a list of every possible telephone number, and from this list, 1000 phone numbers would be randomly selected (Newport, Saad, & Moore, 1997).

If this sampling strategy were used incorrectly (for instance if the sample size were not large enough), the sample would not be truly representative of the larger US population, and therefore the results would not necessarily be valid.

Hint: Read the textbook for detailed explanations of sampling methods.

Provide your survey questions, minimums, maximums, and typical responses: Follow the guidelines in the courseroom for the Project: Designing a Focused Survey assignment. Discuss why these are the best questions and justify your estimated values for the means.

EXAMPLE:

The questions I have chosen are the best questions to use, because they are brief and direct, so that survey participants have a clear idea of what is being asked. The questions are also nonbiased. Additionally, the questions I have chosen specifically focus on variables that I am interested in examining such as age, gender, and educational level. I am interested to know if beliefs and attitudes related to GMOs correlate with these variables. For questions 3 and 4, I arrived at my estimations by reviewing websites and statistical studies related to GMOs.

The questions I have chosen are the best questions to use because they are to the point. The questions are clear and very respectful to help the participants feel comfortable. These types of questions will help determine a certain age obesity starts and the poor dieting that is causing the problem. These types of questions will help find out what race suffers from obesity and must be studied further.
