The Players


Jeopardy! is an American TV quiz game show where contestants are given clues about general knowledge in the form of an answer which they must respond to with the correct corresponding question. Although the show debuted in 1964, our visualizations focus on the program’s most successful syndicated version, which began in 1984 with Alex Trebek as its host.


Jeopardy! Contestants

Jeopardy! has a grueling audition process. Applicants must take a challenging written exam, compete one-on-one interviews and successfully compete in mock games. Only a lucky 0.4% make it on to the show.




Gender Divide

Of the contestants who do get on, fewer are women. The gender gap has long been known to exist on Jeopardy! According to Alex Trebek, the producers have been working over the years to attract more women to the show, which has been successful to an extent. However even with more women on the show, the percentage of winners continues to be less than the percentage of players.






The Production Crew

Some people cite gender bias caused by a lack of females on the production staff. The executive producer and editorial producer who must approve all questions are both male. And currently only 2 out of 8 clue writers are female.

Earnings


Jeopardy! has three rounds: Jeopardy!, Double Jeopardy! and Final Jeopardy! Contestants collectively answer 30 questions in each round before they reach the Final Jeopardy! At this point, they must decide what percentage of their current earnings they want to wager in the final round. It presents them with an opportunity to double it or lose it.

In the next visualizations, you can discover the different habits of contestants making final wagers.


Exploration and Analysis

The first step in our process was understanding and exploring the vast data source of 200,000+ clues, categories and answers. We accumulated 30 years of data about the show from j-archive.com, an amazing unofficial fan created site, and went through the process of sorting the data to segregate each player by their relative final position.

    Here's some questions to investigate:
    Did players who finish first dominate their entire game?
    How close were the contestants to each other in their final standing?




Trend Analysis of Player Performace

The number of episodes that have been captured on J-Archive has drastially changed over time, with a major upward spike occuring in 1996. It's possible that was the year fans began seriously collecting episode data and information before that was captured from VCR recordings. Also, the amount of money that contestants won on the show increases signficantly in 2000 when the Jeopardy! doubled its question values to keep up with inflation and other game shows. Due to the lack of data from earlier years, we found graphs visualizing data on an annual basis to be a bit misleading. To compensate for this, we decided to allow the user to navigate by season (each a year long). By clicking on an episode in the season, one can see how the game played out.

    Here's some questions to investigate:
    Was there an outright winner or a last minute upset?
    Do players on top always bet very safe or have they just become more cautious over time?
    Do players on third never comeback to win? Or is it just a recent trend?

Each season typically starts in September and ends the following July. The heatmap provides a season-level overview of final earnings for all episodes with available data. The darker squares represent higher final earnings.

You can see the lack of data in earlier seasons and the higher earnings in later ones. Can you spot the searson when the clues significantly increased in value?

Mouseover each square for information on the corresponding episode. Click on a square to update the line plot, which shows earnings by each player throughout that game. The lines are shaded based on the position each contestant ended in.





Wagers

As the line plot shows, big changes can happen in the Final Jeopardy! round. First, the Final Jeopardy! category is revealed, at which point contestants decide how much of their earnings they're willing to wager. Once the clue is shown, contestants have 30 seconds to enter their responses onto their electronic displays.

The scatter plot provides a season-level view into how contestants place their wagers. Select a view from the drop down menu: actual wager or wager as a percentage of earnings.

Because the maximum amount one wagers depends their current earnings, first place contestants typically wager more than those in second place, who tend to wager more than third place contestants. However, as a percentage of their earnings, the pattern is the opposite. In the rare cases where players have an unassailable lead, they are more circumspect, while players in third place almost always wager their full earnings since they have nothing to lose.

To bring it all together, the bipartite visualization shows the movement of players between different positions before and after the Final Jeopardy! round. While contestants typically maintain their positions, third place contestants are more likely than those in second place to move up.
