Anxiety and Grade Level

For this assignment you will use data provided to compare the anxiety experienced by students at different grade levels. Using the dataset provided, conduct a one-way ANOVA to determine if there is a significant difference in stress levels between any of the grade levels.

Then, create a report in which you address the following:

• Present the ANOVA results.
• Interpret these results by explaining if there is a significant difference between any of the groups, and if so, how you can tell.
• Reflect on these results and how they fit with your own experiences and expectations.
• Discuss any limitations of ANOVA and explain how they relate to this situation.
