State the variables in the scenario. What are the Independent, Dependent, and Controlled (control) variables?

During a school staff meeting, several staffers mentioned that it seemed to them that students who chose healthier food options at lunch time missed fewer days from school during the school year. The high school dietitian and social worker decided to collect data to test the hypothesis. They received approval from the principal and superintendent to conduct their research study. The dietitian collected data about which students chose healthy food options at lunchtime. She collected data for one lunch period each day. The social worker independently checked the attendance records of the students who had lunch during that lunch period. At the end of the school year, they shared the data they collected over the school year then analyzed the results.

 

(i) State the purpose of the study

 

(ii) State the hypothesis. Explain what information you used to come up with a hypothesis statement.

 

(iii) State the variables in the scenario. What are the Independent, Dependent, and Controlled (control) variables?

 

(iv) Is this a double-blind study? Explain your reasoning.

 

(v) Imagine that you conducted the experiment to test the hypothesis. Provide hypothetical results from the experiment (i.e., provide hypothetical data for the dependent variable). Do your hypothetical results support the hypothesis? Explain your answer.
