The study aimed to determine if the construction of a turf field at Spartan Stadium in 2009 increased the winning percentages of 4 sports teams. ANOVA tests found no significant effect on home winning percentages individually. However, a cumulative test of the 4 teams' home records was significant. Additional data for overall records also showed no individual significance, but combining all teams' data in an ANOVA found the increased winning percentage was dependent on the turf field.

2.  The objective of our study was to
determine whether or not the
construction of Spartan Stadium
and the turf field has increased the
winning percentage of four sports
teams, including Men’s Soccer,
Field Hockey, Men’s Lacrosse and
Women’s Lacrosse.

3.  The turf was constructed prior to
the 2009 season. We collected our
information from the Castleton
Archives for the four seasons since
the turf was built, along the four
seasons prior.
 We performed multiple One-Way
ANOVA tests to determine whether
or not the winning percentage was
dependent on having a turf field.

4.  We hypothesized that the winning
percentage of Castleton’s Sports
teams improved after the
construction of the turf in 2009.

13.  With the exception of Women’s
Lacrosse, the construction of
Spartan Stadium did not contribute
to a higher home winning
percentage. Although the records
did generally improve, the ANOVA
tests showed it was not significant.
Because of this, we decided to
total the home records of all four
teams and run a cumulative
ANOVA on the combined records.

17.  As a result of the increased sample
size, the ANOVA test we ran on the
cumulative home records of the
four teams proved to be
significant.

18.  After the ANOVA test on the home
records of these teams was found
to be significant, we decided to
collect data for these same teams’
overall records (home, away and
neutral) over the same time span.
 Since we are both athletes, we
hypothesized that, as a result of
having turf at home, the away and
neutral records would improve as
well, showing that the overall
winning percentages were
dependent on the construction of
the turf.

27.  Again, with the exception of
Women’s Lacrosse, the
construction of Spartan Stadium
was shown to be insignificant of a
higher, total winning percentage.
Since our previous study on home
winning percentage was revealed
to be significant after increasing
the sample size, we decided to do
the same with total winning
percentage.
