The histogram that shows the salaries of the Jacksonville Jaguars in 2009 shows data that is skewed right. There are two major outliers which are, $13,100,000, and $12,367,500, which are unusual because they are of a much higher amount than what is usually earned by the rest of the team. The bulk of the data lies in amounts that range from $300,000 to $1,000,000. The shape of the data represents a bell curve, because most of the salaries are less than $1,000,000. Standard Salaries Data Mean- $2,006,742.122 Median- $1,016,630 Standard Deviation- $2,741,746.033
Salaries with $100,000 Bonus Data Mean- $2,106,742.122 Median- $1,116,630 Standard Deviation- $2,741,746.033
With the $100,000 bonus, the mean and the median increased by $100,000, because we increased all the salaries by $100,000. However, the standard deviation was not affected, because the distribution of data was not affected.
Salaries with 20% increase Data Mean- $2,408,090.547 Median- $1,219,956 Standard Deviation- $3,290,095.24 With a 20% increase, the mean of the salaries increased by $401,348. The Median increased by $203,326. The standard deviation increased by $548,349. The increases that occurred with the added 20% changed the mean, median, and standard deviation by increasing it 20%. The standard deviation in this case changed, because the distribution of data was affected directly, by 20%.
As a statistician who earns $500,000, I wouldn’t take a preference, because either way I would earn the same amount of $600,000. However, if I were to get promoted in the future, I would prefer the 20% increase, because I would gain more
