Criterion A

Title: NHL Player’s Height Effect the Amount of Penalty Minutes per Season.

Description: I will answer the question of “Does an NHL player’s height effect the cumulative amount of penalty minutes in a season?” using a statistical analysis.

Mathematical Analysis: I will analyze two sets of during this project, which are the player’s height (cm) and their total amount of penalties in a season. I will take the top 100 leading players in total amount of penalty minutes from the 2011-2012 regular season. I will obtain the information from NHL.com. From there I will put the data into a table to perform the chai-squared test, to find out whether or not the two variables are related. I will also put all the data into it to a scatterplot graph to see whether it is a positive or negative correlation.

Criterion B
Data Collection Process:
I collected my data though the NHL.com website for all data used. I put the data into data section then sorted it into an observed table for penalty minutes and height of player. After this I will put the data into a chai-squared test to determine the whether player height independent of penalty minutes.
