Super Bowl History Analysis

Welcome to the website. I hope you enjoy it!

First, let’s find out how many games each state hosted.

In the first 55 Super Bowls, the three states that were the most popular locations for games were Florida, California, and Louisiana. Indiana and New Jersey only hosted the Super Bowl once, with those occurences in the 2010s.

We can look at a representation of which states hosted not only the most Super Bowls, but the most competitive ones as well via a boxplot.

The boxplot enables us to make a few conclusions about the data.

We can see that California tends to host more non-competitive games, whereas Florida (the state that has hosted the most Super Bowls so far) holds more competitive matches than California.

States like Arizona and Michigan also have hosted close matches.

We can look at another graphical depiction in the form of a scatter plot below regarding the deficits in Super Bowl games and the states that have hosted them.

A few notes:

• Double click on a label in the key to isolate that label in the graph
• Single click on a label in the key to remove data from the label in the graph
• Hover your cursor over a data point in the graph to view specific data regarding the data, deficit, host state, and winning team

Through the scatter graph, we can even visualize how host states have changed throughout the treasured history of the Super Bowl.

We can extract information about which states have hosted Super Bowls frequently in a specific decade or time period.

Now, let’s see which 10-year period had more lopsided games. Lopsided games are games where the deficit is significantly high, implying that one team scores significantly higher than the other.

We can see in the bar graph that the 1980s brought more less competitive Super Bowl matches, whereas the 2010s brought more competitive matches.

What will we find if we divide each 10-year period into 5-year periods?

We can see that the matches between 1985 and 1990 were much less competitive than the games in other periods.

Now, which 5-year period had more high-scoring Super Bowl matches?

The bar graph shows that the era between 1990-1995 was the most high-scoring era for Super Bowl games overall.

We can even enlarge the scale to 10-year periods to see which decade boasted more high-scoring games overall.

The bar graph shows that the 1990s boasted high-scoring matches overall.

Let’s now take a general look at how Super Bowl winning and losing scores trended over the first 55 years.

There are several periods where the gap between the winning and losing scores are significant, while there are a few periods where the gap is miniscule.

The NFL is comprised of two primary conferences: the AFC and the NFC. In the Super Bowl, one team from the AFC faces one team from the NFC. Let’s see which conference has won the most Super Bowls so far.

It is evident that the NFC has won one more Super Bowl than the AFC.

The NFC has also scored more points than the AFC.

Each conference has four divisions. Let’s see which division contributes most to Super Bowl wins by examining the number of games won by each division. Conversely, we can see which division has lost the most games.

The NFC East has won more Super Bowl games, while the AFC East has lost more Super Bowl games.

The bottom two graphs highlights a line graph representing trends in winning scores, while each point is colored by a division. Take advantage of the plotly features to examine the graph.

The two graphs allows us to see various trends, including which division appeared the most (and the least) in Super Bowl matches, which division participated the most in various decades, and even which division tends to score more.

Similar to the graphs regarding trends in winning and losing scores labeled by division, we can compare trends by conference as well.
