What’s Going On in This Graph? | May 3, 2023


Note: This is the final “What’s Going On in This Graph?” for the 2022-23 school year.

This graph was previously published in The New York Times. It includes data through the first three weeks of each Major League Baseball (M.L.B.) season since 1980. How has the duration of baseball games changed this year, and how might this affect the popularity of the sport?

This season, M.L.B. introduced major rule changes: a pitch clock limiting the time that a pitcher has to throw a pitch and a hitter has to be ready for pitches, a ban on the infield shift where outfielders had moved around the field to be in better position to field hits, and a limit on pickoff throws for outs by the pitcher. In addition, bases are bigger (18 inches square, from 15) and pitchers and catchers may wear PitchCom transmitters to communicate secretly while on the field.

On Wednesday, May 3, we will moderate your responses live online. By Friday morning, May 5, we will provide the “Reveal” — the graphs’ free online link, additional questions, shout outs for student headlines and Stat Nuggets.

1. After looking closely at the graph above (or at this full-size image), answer these four questions:

The questions are intended to build on one another, so try to answer them in order.

2. Next, join the conversation online by clicking on the comment button and posting in the box. (Teachers of students younger than 13 are welcome to post their students’ responses.)

3. Below the response box, there is an option to click on “Email me when my comment is published.” This sends the link to your response which you can share with your teacher.

4. After you have posted, read what others have said, then respond to someone else by posting a comment. Use the “Reply” button to address that student directly.

On Wednesday, May 3, teachers from our collaborator, the American Statistical Association, will facilitate this discussion from 9 a.m. to 2 p.m. Eastern time.

5. By Friday morning, May 5, we will reveal more information about the graph, including a free link to the article that includes this graph, at the bottom of this post. We encourage you to post additional comments based on the article, possibly using statistical terms defined in the Stat Nuggets.

We’ll post more information here on Thursday afternoon. Stay tuned!
