Please answer the following questions from A) to E) using the photo below. A) What is the independent variable in this study?B) What are the dependent variable is in the study?C) Explain why the researchers were able to use a one-way within groups ANOVA in the situation. D) n^2 Is roughly equivalent to r^2. How large is each of these effects based on Cohen's conventions?E) The researchers drew a specific conclusion beyond that there was some difference, on average, in the dependent area balls, depending on the particular levels of the independent variable. What additional test where they likely to have conducted? Explain. Be sure to show your work, explanations, and answer all for a thumbs up! I have trouble understanding this questionThanks

13.28 Pilots' mental efforts and a one-way within- groups ANOVA: Researchers examined the amount of mental effort that participants felt they were expending on a cognitively complex task, piloting an unmanned air vehicle (UAV) (Ayaz, Shewokis, Bunce, Izzetoglu, Willems, & Onaral, 2012). The research- ers used the Task Load Index (TLX), a measure that assesses participants' perception of their mental effort following a series of approach and landing tasks in 30ussimulated UAV tasks. They wondered whether exper- AVOtise would have an effect on perceptions of mental effort. In the results section, the researchers reported the results of their analyses, a series of one-way repeated-measures ANOVA. "The results indicated a significant main effect of practice level (beginner/ (intermediate/advanced conditions) for mental demand (F (2, 8) = 17.87, p
