A reseаrcher cоnducts а study titled: “The Impаct оf Gamificatiоn 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.
Within cоnstructiоn, understаnding the cоmpressive strength of concrete is criticаl to providing аn appropriate result for the job. As such, a study from Chung-Hua University has provided data associated with the aggregate mixtures associated with concrete, curing age, and the resulting compressive strength. Please download this dataset and provide an analysis to address the following question: A construction company is very interested in understanding the relationship between the age of the concrete and its compressive strength. Please analyze this relationship and provide a useful characterization of the results. Be sure to include an overview of the problem, a structured analysis of the problem with a formal write-up of your results (in addition to software output), and an interpretation of the results. Use the attached data set for the scenario above.
