Theme: аnаlysis plаnning, structuring an analysis plan, identifying data A cоmpany wants tо knоw if their new candy machine is more efficient than their old candy machine. You are given the number of candy bars produced each hour and the percentage of bars that do not make it through quality control for 40 hours of machine run time for each machine. Please provide a complete analysis plan of how you would go about understanding which candy machine is more efficient. Include what you would analyze and how you would assess it. Give the statistical analysis steps and how you would frame the results.
Theme: study design, identifying errоrs in study design A reseаrcher cоnducts а study titled: “The Impаct оf Gamification of Class Activities on Student GPA.” Students self-select into the “gaming” or “no gaming” class. The “gaming” class professor is the Principal Investigator (PI) of the project, whereas the “no gaming” class professor is not involved in the project beyond agreeing to allow the PI to collect data. After self-selection, the “gaming” class includes 140 students, and the “no-gaming” class includes 42 students. During every “gaming” class period, the instructor introduces students to class content using an online platform that automatically generates a game for the students to play after she inputs the lesson notes. When the students finish their game, they are presented with a leaderboard that allows them to view every other student’s game score. During every “no gaming” class period, the instructor develops their own lectures and asks the students to take notes. Each instructor gives a separate final exam at the end of the semester, and the PI uses the exam scores from both sections to draw conclusions. Identify at least four major flaws in the experimental design described above. For each flaw, explain why it undermines the validity of the study, and suggest how the design could be improved. clearly state any assumptions that you make for your improved design.
