Accidentally misleading visualizations

Today I saw a figure posted on Nate Silver’s website that is a good example of an accidentally misleading visualization. The intended point of the chart is that most men in Glamour Magazine have some form of facial hair.

Instead, what immediately comes across is that most men in Glamour Magazine are clean-shaven. The figure forces the reader to first group facial hair categories before it becomes obvious that most men maintain some form of facial hair.

Here are a couple of different approaches I think are better. By listing the facial hair categories first and using color to help the reader group them, figure A requires minimal changes to the original visualization. Figure B groups the facial hair categories to show that clean-shaven is in fact in the minority. Figure C adds color to really emphasize that the comparison is between facial hair and clean-shaven. In figures B and C I think that the numbers are optional.

Facilitating feedback and improving learning

This is an app idea I came up with to improve student learning.

Students, who are the customers of education, have little input. Teachers, who heavily influence student learning, lack the data to improve teaching. Administrators, who can promote change, have little information.

The auris app is designed to facilitate feedback and serve as a powerful tool to empower students, enable teachers, and inform administrators.

What do you think? Anyone want to help me build the app?

Kevin Durant’s Wingspan in Perspective

In light of Magic Johnson’s recent prediction about Kevin Durant, I decided to objectively evaluate the physical characteristic that sports commentators most often mention in regards to Durant: his wingspan.

Since height has a large impact on wingspan, I evaluated Durant’s wingspan relative to NBA prospects since 1989 who are his height within an eighth of an inch. The wingspans of these players range from 6′ 8” to 7′ 6.25”, and sure enough Durant is near the top of the distribution.

Obviously a long wingspan is not the only thing that contributes to Durant’s basketball prowess, but I’m sure it helps. Thanks to DraftExpress for the data!

Leadership lessons from Pop

Gregg-Popovich-507433-1-402By any metric you’d like to use, Gregg Popovich is one of the most successful NBA coaches of all time. He has won 4 NBA championships and keeps the San Antonio Spurs competitive and in the hunt for a title every year. I think some recent comments to the San Antonio Express-News reveals a little bit of the secret to how he has been so successful:

Sometimes in timeouts I’ll say, ‘I’ve got nothing for you. What do you want me to do? We just turned it over six times. Everybody’s holding the ball. What else do you want me to do here? Figure it out, and I’ll get up and walk away. Because it’s true. There’s nothing else I can do for them. I can give them some bulls—, and act like I’m a coach or something, but it’s on them.

I have observed that sometimes people in leadership positions fail to put people in situations where they can succeed, and then put the blame on the individual who ultimately fails. The reality is that there has been a failure in leadership. In basketball terms, the play was drawn up poorly, so why blame the player who sought to execute the poor play? What Coach Popovich is pointing out is that the leader isn’t always the one who can come up with the best play, and that he allows his players to take an active role in planning for success. Clearly Coach Popovich understands that leadership isn’t about power, it is about empowering.

I think competitive character people don’t want to be manipulated constantly to do what one individual wants them to do. It’s a great feeling when players get together and do things as a group. Whatever can be done to empower those people.

More than anything, leaders are facilitators. This is why leaders who fall into the trap of flexing muscles and seeking to manipulate ultimately fail, they destroy the very people who can bring success to the organization. Coach Popovich sums this point up beautifully:

It’s a players’ game and they’ve got to perform. The better you can get that across, the more they take over and the more smoothly it runs. Then you interject here or there. You call a play during the game at some point or make a substitution, that kind of thing that helps the team win. But they basically have to take charge or you never get to the top of the mountain.

With true leadership the battle becomes personal because it isn’t about the coach, it is about the team.

Scaling fences

IMG_20140208_154942Today my daughter Sophie decided to climb a chain-link backstop at the nearby school. I knew she loved to climb things on the playground, but I had never seen her attempt something like this. I was a bit apprehensive as she started to scale the backstop and so I ran over and told her I would catch her if she fell. Shortly thereafter, and about two-thirds of the way up, she panicked and decided she needed help coming down. As I thought about it later, I helped her fail because I gave her an easy way out.

After a few minutes I saw her back at it and this time I didn’t let her know I was there in case she fell. She smoothly navigated to the top and proudly looked around to take in the glory of her accomplishment.

Of course, not to be outdone by her older sister, my darling Ellie did some fence scaling of her own. Next time I’ll have to make sure she has better shoes for the climbing.

How often do we go two-thirds of the way up our individual challenges and then allow ourselves to panic and turn back? How often do we undermine the growth of others because we talk more about how it’s okay if they fail than about how they can succeed?

The friendship of a grandma

DSCF1721wA year ago my sister sent me an email with the subject: Grandma made it to her real home…6:41am.

Pauline Goodwin passed away at the grand age of 99. I always felt a special bond with Grandma Goodwin because we shared a love of sports, particularly basketball. As a boy and on into adulthood I spent many evenings watching basketball with her. Grandma’s favorite team was the San Antonio Spurs and so one year I bought her a Tim Duncan jersey that she proudly displayed on her wall during basketball season.

Although I’d like to think I had a unique relationship with Grandma Goodwin, the reality is she found a way to make everyone she met feel special. This doesn’t mean Grandma was a pushover by any means, in fact, she was known to speak her mind. For example, once when one of my brothers grew a bit of a beard she remarked, “grow it out, and then shave it off.”

A short blog post can’t begin to describe this great woman and the influence she has had on my life. In October when my unborn son unexpectedly passed away a few days before his due date it didn’t take long for my wife and I to choose Goodwin as his name.

The other night I asked my three year old Elinor where baby brother was, she replied, “baby brother is with Grandma Goodwin.” If my son is anything like his dad he probably is with Grandma Goodwin, watching basketball.

Basketball, dunks, and the game of life

vince-carter-olympic-dunkIn the 2000 Olympics Vince Carter (6′ 6″) posterized Frédéric Weis (7′ 2″) in one of the classic dunks of all time.

Posterizing opposing players by dunking over them is kind of like a home run in baseball, it is guaranteed to show up on SportsCenter. Unfortunately, the stigma of being dunked on has led many players to frequently turn down opportunities to defend dunk attempts. This attitude is essentially the idea that “If I can’t win, I won’t play”.

One of my favorite basketball players is Nate Robinson because he welcomes the opportunity to challenge others at the rim, despite the fact that he is only 5′ 9″. The list of players he has challenged at the rim, and won, includes LeBron James (6′ 8″), Yao Ming (7′ 6″), and of course Shaquille O’Neal (7′ 1″). Check out this clip of Nate Robinson getting blocked by the intimidating Shaq, only to come back and return the favor.

Perhaps the most meaningful battles we fight in life are the ones where we aren’t favored to win. As a Texan I naturally think of the Alamo and the bravery of the men who refused to surrender, even though they knew they had no chance of victory. Life is too short to turn down opportunities to block a dunk, even if it means you might get posterized. I’d rather be posterized in the game of life than sulk on the sideline wondering what could have been.

 

He was an average student, but was a bold child

AitazazI am touched by the story of Aitazaz Hassan Bangash who sacrificed his life to prevent a terrorist attack at his school in Pakistan. Here is an excerpt from the story on CNN:

A 14-year-old boy is being hailed as a hero in Pakistan for tackling a suicide bomber — dying at the main gate of his school and saving schoolmates gathered for their morning assembly.

 

Ninth-grader Aitazaz Hassan Bangash was on his way to the Ibrahimzai School on Monday in the Hangu district of northern Khyber Pakhtunkhwa province when the bomber, dressed in a school uniform, asked him where the school was, the teen’s cousin told CNN.

 

Aitazaz and his cousin, Musadiq Ali Bangash, became suspicious, Musadiq said. “The other students backed off, but Aitazaz challenged the bomber and tried to catch him. During the scuffle, the bomber panicked and detonated his bomb,” he said.

 

I find it interesting what Aitazaz’s teacher said of him:

He was an average student, but was a bold child.

 

Why must Aitazaz’s boldness be prefaced with the revelation that he was an average student? Are only above average students expected to be extraordinary? Let me clarify that I am not blaming his teacher; I am merely illustrating how ingrained academic achievement is in our assessment of people.

In the moment of crisis Aitazaz proved that he was not an average individual. Aitazaz was bold, and it was his boldness that saved the lives of over 400 of his peers.

As a society we are obsessed with smart people. In our love affair with being smart, have we overlooked other traits that are arguably more valuable than dominating a standardized test?

Perhaps part of the legacy of Aitazaz can be that it prompts us to reconsider the merit of using academic achievement to define and predict future success.

Is Charlie Strong the right choice for Texas?

Charlie Strong Longhorns_1388959402512_5055663_ver1.0_640_480Red McCombs, a wealthy and powerful booster at the University of Texas, recently called the hire of Charlie Strong a kick in the face. Here is a portion of the dialog as posted on ESPN:

“I think the whole thing is a bit sideways,” McCombs said of the selection process during an interview with ESPN 1250 San Antonio. “I don’t have any doubt that Charlie is a fine coach. I think he would make a great position coach, maybe a coordinator.

 

“But I don’t believe [he belongs at] what should be one of the three most powerful university programs in the world right now at UT-Austin. I don’t think it adds up.”

If you are Strong this is probably not how you’d like to begin your tenure as head coach, with a vote of no confidence from boosters. But this is the type of adversity Charlie Strong has dealt with his whole coaching career, and this is exactly why he is the right choice for Texas.

Strong is a man who was looked over many times for head coaching positions until Louisville finally gave him a chance. He went to Louisville and delivered, his record speaks for itself. While McCombs may have wanted the likes of Jon Gruden, or another celebrity, Texas chose to go with a college football coach with a chip on his shoulder.

Red McCombs’ criticism might just be the best gift he’s given to UT, he helped stoke the fire that drives Charlie Strong. Strong will make Texas a perennial winner again because he will impose his will on the program. Strong is one of those unique individuals who takes criticism and lets it fuel him, not destroy him.

Take your shots at Charlie Strong if you’d like, and no disrespect to Mack Brown, but Strong is exactly what UT needs, a football coach who refuses to back down, especially when he is challenged.

The future of college football on ESPN

I should be watching the Fiesta Bowl right now, but I refuse to subscribe to cable or satellite TV just for ESPN. It just isn’t worth it. According to an article in the New York Times I’m not the only one who finds that streaming content is quickly replacing cable TV. What does this mean for college football?

In recent years ESPN has taken over the market for college football, leaving only a few token bowl games for broadcast TV. ESPN has always televised most bowl games, but the important ones, the BCS bowls, were always on broadcast TV. In 2010 ESPN took over the BCS bowls as well. When the College Football Playoff replaces the BCS next year it will be on ESPN. Below is a plot I made that illustrates the ESPN takeover.

bowl_games

I’m sure ESPN is enjoying the profits of college football, but it may also be alienating young viewers who are too money savvy (or just poor) to purchase cable. Despite the recent popularity of college football, ratings for the BCS Championship Game have actually gone down since ESPN took it away from broadcast TV (16.5 average rating in the previous 8 years on broadcast, 14.8 average rating with ESPN the last three years).

The sad reality is that I am used to not watching bowl games now. ESPN has turned a once-avid college football fan into an apathetic observer. I don’t care if I can’t watch.

So what does this mean for college football? Perhaps the popularity of college football will begin to diminish because college kids who can’t watch the game won’t care about the game. I realize that most of the college football money isn’t coming from college kids, but college kids become adults: adults who have lost interest in college football because they couldn’t watch it in college.
