      ISSUE: Controversial calls continue to affect the outcome of sporting events.
    • Instant Replay Jurisdiction

      forward passed
      fumbles
      down-by-contact plays
      forward progress plays
      touching of a kick and placement of the football.
    • Instant Replay Jurisdiction
      Major League Baseball (MLB)

      National Hockey League (NHL)
      Review calls on controversial goals scored.
      National Basketball League (NBA)
      Review shots made before the buzzer.
    • Questions To Be Answered
      Is Instant Replay at an appropriate level in sports?
      Does Instant Replay have a positive impact on sports?
      Does Instant Replay ultimately make the games more fair?
    • Questions To Be Answered
      Concerns:
      Does Instant Replay slow down the pace of the game?
      Is it practical to implement Instant Replay in Division II and III sports?
    • World Cup: England vs. Germany
    • Additional Controversies
      MLB:
      Detroit Tigers vs. Cleveland Indians
      Galarraga Perfect Game lost on final call.
      Philadelphia Phillies vs. Florida Marlins
      Gaby Sanchez walk off hit ruled foul.
      (WS) San Francisco Giants vs. Texas Rangers
      Double play was ruled safe at first base.
    • Main Research Hypothesis
      Question: Should Instant Replay be further implemented in sports?
    • Data Collection & Preparation
      Collection Methods
      Used Survey Monkey (Sample Size 40)
      10 MC Scaled Response Questions.
      Used on Facebook as an event.
      Interviews (Sample Size 20)
      Target Audience
      Sports Fans/Followers

      11 to 15- 4
      16 to 20 - 6
      20+- 3
    • Descriptive Statistics
      Mode is 6 to 10 hours
      Median is 6 to 10 hours

    • Probability
      Probability of choosing someone from our data who watches football the most.

    • Hypothesis Test for Fairness
    • Descriptive Statistics
    • Conclusion and Recommendations
      The average (mean) for hours of sports watched per week was 9.1125
      75% of the sample played sports at a competitive level at some point in their lives.
      37 of the 40 people surveyed agreed that instant replay has a positive impact on sports.
      65% also agreed that usage of instant replay slows down the game.
    • Conclusions and Recommendations
      29 of the 40 people sampled agreed that instant replay is at an appropriate level at this time.
      23 of 40 feel that it is not practical to implement instant replay in Division II and Division III sports.
      95% of the sample agreed that instant replay corrects mistakes made by officials.
      90% of the people surveyed agreed that instant replay makes the gameplay more fair.
    • Conclusions and Recommendations
      Given the data collected, we determined that instant replay should be implemented across all professional sports.
      For the sports in which instant replay is already utilized, it should be refined and used to a further degree.
      As a group, we collectively believe in the usage of instant replay for professional and college sports.
    • Suggestions for Improving Study
      Conduct survey to broader age groups.
      Ask more questions regarding each sport individually.
      Acquire a larger sample size with more participants.
