NHL Hockey Statistics Introduction A study of the NHL statistics for the top 100 players in the league was conducted in order to advise and present information to people heading the Avalanche Hockey team in Denver, Colorado. This information will be presented to the coach, Patrick Roy, and the owner, Ann Walton Kroenke. Using various NHL resources online, I found the ranking of the teams and the top 100 players in the league. The dependent variable in my study is the player ranking and the independent variables are games played, goals, assists, points, plus-minus, penalty minutes, points per game, power play goals, power play points, shorthanded goals, shorthanded points, game winning goals, overtime goals, shots, shooting percentage, time on ice per game, shifts per game, and faceoff win percentage. I chose these statistics because they represent how the player performs in all aspects of the game, showing the statistics of the player as a whole, rather than simply as an offensive or defensive player. Only 10 of the continuous variables listed above were chosen for descriptive statistics. Variable Descriptive Statistics Along with determining the mean of these categorical variables, I found the skewness and the standard deviation. Skewness shows the distribution of outliers from the mean: if skewness is in the range of -1 to 1, the skewness is normal. If it is above 1, the outliers tend to be above average. If it is below -1, the outliers tend to be below average. Variable Mean Standard Deviation Skewnes s Normal? GP (Games Played) 78.36 4.7 -1.9 Skewed below average G (Goals) 24.06 8.3 0.27 Normal P (Points) 60.5 10.2 1.6 Skewed Above the Mean A (Assists) 36.44 9.2 0.8 Normal PIM (Penalty Minutes) 40.95 23 1.6 Skewed Above the Mean PPG (Power Play Goals) 6.73 3.7 0.86 Normal SHG (Shorthanded Goals) 0.53 0.83 2 Skewed Above the Mean OTG (Overtime Goals) 0.8 1 1.5 Skewed Above the Mean S (Shots) 203.8 2 51.63 0.6 Normal S% (Shooting Percentage) 11.934 3.4 -0.2 Normal

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
