How to perform two factor anova? Solution and explanation please 3. The following data are representative of many studies examining the relationshipbetween arousal and performance. The general result of these studies is that increasingthe level of arousal (or motivation) tends to improve the level of performance. (Youprobably have tried to "psych yourself up" to do well on a task.) For very difficult tasks,however, increasing arousal beyond a certain point tends to lower the level ofperformance. (Your friends have probably advised you to "calm down and stay focused"when you get overanxious about doing well.) This relationship between arousal andperformance is known as the Yerkes-Dodson law.Factor B Arousal Level120= 120 5SeosyMediumLowHigh103014108146.6.7.T.90ROWI6.9EasyM = 3M = 5M = 10T = 15T = 25SS = 28T = 50SS = 18SS = 26N = 30FactorG = 120A TaskDifficulty217.1EX² = 8606.TROW2 = 30Difficult1M =1M = 3M = 2T = 5T = 15T = 10SS = 20TCOLI = 20 T.o2 = 40 To1a= 60SS = 8SS = 20COL2Use a two-factor ANOVA with a = .05 to evaluate the significance of the maineffects and the interaction (conduct all 4 steps!).b.

Many institutes, departments, and recruitment committees are using citations as part of the assessment process involved in making new appointments. By going through scientific databases like Scopusselection panels can check if a candidate’s work is making an impact by being cited by other researchers in their field. How does the scientific community measure how "good" or "great" a journal or an author is? How do you determine the "impact" of an author's work? The most 2common metric to track an author's impact is ask how often they are cited. The following table presents the number of citation on research publications of two Management Science professors over a period of 17years, 2005 to 2021, data taken from Google Scholar. The objective of this assignment is to find a suitable forecasting method (moving average, exponential smoothing, and/or simple linear regression model) to predict near future citation of a researcher.
