Transcript of Ben Roethlisberger

Ben Roethlisberger I chose to use the statistic of quarterback rating because the rating measures the preformance of the quarterback. It tells how well Ben played in that game, it rates him. Benjamin Todd "Ben" Roethlisberger was born on March 2nd, 1982. His nickname is Big Ben. He is an American football quarterback playing for the Pittsburgh Steelers. He is the yougest Super Bowl-wining quarterback in NFL history. Critical days include:
Regarding the regression executed on how much the preformance of Ben Roethlisberger varied above and below his average based on three biorhythm curves, it is inconclusive that the theory of boirhythms is valid. With most correlations being around 50%-60% evidence fails to support the biorhythm theory that emotional, physical, and intellectual preformance correspond to a sinusoidual wave beginning at a persons birth. There were no games on a Critical Day. The correlations are as following:
Physical:
8 in line with the biorythm, 6 out of line
For an accuracy of 8/14 = 57%
Intellectual:
8 in line with the biorythm, 6 out of line
For an accuracy of 8/14 = 57%
Emotional:
7 in line with the biorythm, 7 out of line
For an accuracy of 7/14 = 50%
The correlation for the mastery was;
8/14 = 57%
Which is not an improvement from the regular biorhythms. The biorhythm theory is that the cycle of human preformance is cause by the cycles of a biorhythm. There is an intellectual, emotional, and physical curve. The curve begins at birth and continues until the day of death. According to the theory there are good days and bad days, a good day would be where the curve is at a maxima and a bad day would be where the curve is at a minima. The point at which the curve crosses the x-axis is a "critical day". A critical day consists of an "unstable" day.
If the theory is to hold true, the statistics obtained from a football quarterback should show that his preformance was above average on a "high" day, and below on a "low" day. Bibliography
