In the season 2016-2017 Chelsea won English Premier League. Ron and Tom, fans of Chelsea, argued which factor was more important for winning the League: the number of goals scored or the number of goals conceded. Using the information about the results of the season 2016-2017 represented in the table below ( http://www.espn.com/soccer/standings/_/league/eng.1/season/2016/sort/points) , find out, which factor has been statistically more important.
A) The correlation coefficient between the goals scored (goals for) and the points
is close to 1, so there is a strong positive linear relationship.The correlation coefficient between the goals conceded (goals against) and the points
is negative, so there is a weak linear relationship.So statistically more important factor is the number of goals scored.
B) The absolute value of the correlation coefficient between the goals scored (goals for) and the points
is greater than the absolute value of the correlation coefficient between the goals conceded (goals against) and the points
, so statistically more important factor is the number of goals scored.
C) The correlation coefficient between the goals scored (goals for) and the points
is close to 1, so there is a strong positive linear relationship.The correlation coefficient between the goals conceded (goals against) and the points
is negative, so there is a weak linear relationship.So statistically more important factor is the number of goals scored.
D) The absolute value of the correlation coefficient between the goals scored (goals for) and the points
is less than the absolute value of the correlation coefficient between the goals conceded (goals against) and the points
, so statistically more important factor is the number of goals conceded.
