Assignment:

A group of investigators are interested in assessing whether a newly planned nutritional education program in low-income neighborhood elementary schools might contribute to better eating habits among the schoolchildren. You have been hired to advise them on the methods for this quantitative study.

a. In a few sentences, explain why a quasi-experimental study may be more suitable than a randomized controlled trial for this study

b. Write a quantitative research question for this study in the form of a complete sentence. Clearly identify each element of the PICOT.

c. Propose two different methods of measuring the dependent variable in this study. For each one, provide a description of how the data would be collected and the type of variable it will yield.

d. Describe in a few sentences the type of information that should be included in the table of descriptive statistics  and list four variables you would include for the study of nutritional education programs.

e. Describe two possible limitations of using an uncontrolled quasi-experimental study design that may bias the study results. When describing the limitations, be clear about how they apply to the specific example of nutritional education programs and eating habits. For each limitation, suggest a method to minimize the potential bias and state clearly how the implementation of your proposed method would help to reduce the potential bias.

f. Upon completing the study on nutritional education programs, the investigators report that there is a statistically significant difference in eating habits between the children who received the intervention and those who did not, with p<0.05. What additional information.
