Revise and complete question 1.4 – grouped and ungrouped

Professor feedback:
Thank you for your response to this problem. To improve your performance here, be sure to apply the definitions of grouped and ungrouped data to each scenario to demonstrate how this data should best be organized for display. Also be sure to include a complete justification as to why you selected grouped or ungrouped. There are 3 or more errors among your responses. Consider grades for a brick-and-mortar, Intro to Psychology course at a large University with over 1000 students in the section of interest. How would you want to display the final grades for this course? With every grade for every student listed (ungrouped) or perhaps collapse into intervals by letter grade (grouped)? What if you took this same course, and instead wanted to classify students by year in school (assuming that most students are in school for 5-6 years). Would you want to list every year in school (ungrouped)? Or would you want to collapse these into intervals (such as years 1-3 and then 4-6) and make it grouped?
