Answer:
B. They believe that historical trends will persist into the future
Explanation:
The Quantitative Forecasting Method employs statistics to predict future occurrences by analyzing historical data and its impacts.
These approaches rely on mathematical frameworks and are predominantly objective. They are based on mathematical computations. Some examples of methodologies in Quantitative forecasting include the Delphi technique, Sales force polling, and Consumer surveys.
Across all these strategies, specialists examine historical trends to forecast future events; however, the prior trends may not necessarily replicate in the future.
Answer:
0.146
Explanation:
Cohen's d is calculated by (mean of experimental group - mean of control group) divided by standard deviation
Cohen's d= (8-7.4)/4
= 0.146
The Yerkes-Dodson Law postulates a direct correlation between arousal and performance.
Explanation:
The Yerkes–Dodson Law is a well-documented connection between arousal levels and performance, attributed to psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. This principle indicates that as arousal, either mental or physiological, increases, performance improves, but only to an extent.
The Yerkes-Dodson Law indicates a linear relationship between arousal and performance. Essentially, a rise in arousal up to a specific threshold can enhance performance. However, if arousal surpasses that optimal point, a decline in performance can be observed.
