TVS 5205: Aviation Statistics 

An aviation student researcher examined the relationship between pilots’ simple visual reaction times and experience, which she defined as number of flight hours including simulator time.Visual reaction time was measured by having participants press a joystick immediately at tire appearance of a suprathreshold spot target and war measured in milliseconds. (Note: 1000 milliseconds - I second.) The reaction times are considered “simple" because participants did not nave to make any decisions regarding if or when to press the joystick. The file “Graded Assignment 5" contains a copy of the data the student collected from a random sample of airline transport pilots (ATPs) who agreed to participate in the study and self-reported their total flight hours. The researcher surmised that these two variables should have a strong, negative correlation: As pilot experience increases, their visual reaction times should decrease, which indicates faster reaction times.

A. Pre Dat A analysis (5 points)

1. Specify the research question and corresponding operational definitions.
2. Specify the research hypothesis.
3. Determine the appropriate research methodology/design and explain why it is appropriate.
4. Conduct an a priori power analysis to determine the minimum sample size needed. Compare this result to the size of the given data set and explain what impact the size of the given sample will have on the results relative to the minimum size needed.
