Statistics Done Wrong

One of my most frustrating pet peeves is when scientists don’t understand what it is they are measuring.

And, let me assure you, this is a much bigger problem than anyone is willing to admit.

My background – going way, way back, before my ventures into the business world or even into parenthood, I studied Science.  And, while I never sought a doctorate or any such thing (I had done my due diligence on child-bearing statistics in preparation for parenthood and realized that if I wanted to optimize for my children’s intelligence, I had to conceive my first child at no older an age than 25 – and my last one at no older an age than 30:  and since my then fiance – now husband – agreed that we did not approve of the ‘daycare’ model of child-rearing, somewhat to my now hubbie’s chagrin, I chose not to pursue further studies), I do have a degree in Physics in there somewhere….

What I specialized for (though I did not realize at the time that this was ‘soooooo Aspie’) was data acquisition, test and measurement.  I made a career out of helping other scientists (and industry, military etc.) figure out how to measure what it was they were really trying to measure, from designing the data acquisition systems to telling them if they were actually measuring what they thought they were measuring.

As such,  am somewhat sensitive to ‘sloppy science’.

Which is why I so happy that my son has forwarded me a link to an absolutely excellent essay about how statistics – especially in the medical field -(where, when I was finishing my degree, I was heavily lobbied to go into post-grad, so that I could ‘clean-up’ the methodology in a prominent Canadian immunology University lab – so I really, really understand the criticism here…) are misunderstood not just by the public, not just by the media people who are reporting on it, but especially by the scientists themselves who are carrying out the studies/experiments!

‘Open a random page in your favorite medical journal and you’ll soon be deluged with statistics: t tests, p values, proportional hazards models, risk ratios, logistic regressions, least-squares fits, and confidence intervals. Statisticians have provided scientists with tools of enormous power to find order and meaning in the most complex of datasets, and scientists have embraced them with glee.

Many of these tools are misapplied or misinterpreted.

In fact, most published research findings are probably false.’

Aye, aye.

The essay is written with the layman in mind:  it explains things, from first principles, without jargon but with examples of just how easy it is to manipulate results, even without realizing one is doing so.

IF you are interested in science…

IF you have not taken a lot of courses in statistics – but want to understand the real-life meaning of statistics…

IF you want to keep ‘science honest’ ….

IF you question ‘politicized science’…

…you would benefit from/enjoy reading this simple essay.

Q&A on Aspergers and ‘hearing dyslexia’

Recently, I got a question on my post ‘Aspergers and ‘hearing dyslexia’.

When my highly imperfect answer topped a thousand words, I thought it worth a post of its own, because I think that while some Aspies might find it useful, others might  have helpful suggestions – much better than mine, which, if they are willing to share, could benefit us all.

Question:

My son is 16. We didn’t notice this “hearing dyslexia” for many years [perhaps we were too distracted by the other symptoms] but now it is overwhelming. Unless someone speaks very slowly and distinctly to him, my son will answer, “What did you say?” almost inevitably.
My question is: Am I understanding correctly that there’s really nothing to be done about this? My son can read great, can speak [though he tends to speak way too fast and mumbled; doesn’t seem like he used to as a child], but he definitely has the problem listed on this site.
Nice to know what it is, but beyond that, no suggestions?

Answer:

This is a difficult question.

Something can be done, but…

There are therapies which have been used on young children – 3-6 years of age – which are showing definite improvement. This therapy is in the form of computer programs where they do simple tasks (say, help frog catch a fly) based on the length of a tone…which later builds up into series of 2,3+ tones done in the proper rhythm.

The theory behind this is neuroplasticity: the brain is being trained, slowly but surely, to use a different bit of the brain to do the job of integrating time with sound. Because the different bit of brain uses a slightly different ‘strategy’, even to accomplish the same task, the underlying problem will not interfere with that task.

Of course, trying to get a 16-year-old interested in a video game designed for 3-year-olds is not likely to have positive outcome.

But, there are other ways.

They are less effective, but they can work. And, for a 16-year-old, they are more practical.

It really depends on the Aspie: what will motivate them and what will work for each one individually.

One thing that helped both my sons was music.

With a metronome. (One on their computer was more ‘fun’ than a real one – plus it’s much cheaper.)

The sounds are written down in the music score – not just the tones, but their lengths and pauses.

He creates the sound on his instrument (from a cheap recorder or little keyboard to a sexy instrument he’d be willing to play, this bit is way less important) based on what is written down and the metronome helps him integrate the time element into the sound which is generated based on the visual input from the music score. Listening to himself play is the feedback…

I think the visual component is important – ‘playing by ear’ lack the rigor of integrating visual stimulus with the tone and metered time elements necessary to help re-route the ‘time-sound-synchronization’ bit into another area of the brain. Then, as he learns the piece (motor nerve integration into the time/sound system), the metronome can eventually be eliminated and he will still be able to ‘keep pace.

This is not a quick and easy solution, but one that might make an improvement in a teen. We definitely saw an improvement in ours once they took up an instrument – but only an improvement…certainly not an elimination of the problem.

Of course, the ‘shortcut’ would be the videogames where the computer plays the music and displays the colour-coded notes which have to be pressed for a specific period of time, which information is conveyed visually. (Games like RockBand and so on.)

Now that I come to think about it, these are the ‘teenager’ versions of the young-kid games used in the therapy which has been demonstrated to be effective in clinical trials for 3-6 year-olds!

Music could not ‘work’ for me – not only am I not interested in it, I find music actively annoying. Yes, I am sure that my hearing dyslexia is at least partly to blame – imagine listening to music, but with some of the notes jumbled up…you, too, might find it gives you headaches. (This is one of the reasons I avoid shopping malls and other places that force music at me.)

And even though I took piano lessons, within 2 years, 3 teachers kicked me out as ‘un-teachable’…so, no, for me, music absolutely did not work. (For example, I still have difficulty telling apart the movie themes from ‘Star Wars’ and ‘Indiana Jones’ – the same pathetic bombast, the same notes, just slightly re-ordered. Unless I hear them together, I have to think very, very hard to tell which one it is…)

However, what did work for me (a bit) was learning to speak foreign languages. Practicing making the sounds in front of a mirror, getting audio feedback to make sure I eliminated mispronunciation, and so on. (If you want to get really fun, you can use an oscilloscope to display the proper sound wave pattern, then try to match yours to it – hours of fun!)

Learning a language (even without the oscilloscope), I could use the audio, visual and work in the timing with the motor nerves of speech.

And the hook that kept me interested in learning languages was the pattern-making intricacies of grammars. Yes, grammars: because each language has a different approach to this and exploring this logic puzzle set my endorphins hopping! (I get happy just thinking about it!) It’s kind of like algebra, but with words.

(OK – the different alphabets were fun, too – but grammars are like logic puzzles on steroids! Especially when you compared the grammatical ‘philosophy’ to the culture it was used in and the religious memes it best supported – what could be more fascinating!!! But, I’m off on a tangent…)

Again, I am nowhere near ‘cured’, but it certainly helped me become more functional.

I still have extreme difficulty understanding spoken words when there is background noise – like, hum of other conversations, but, especially, music. That is why I loath movies – their background music is not just icky to listen to and calculated to be emotionally manipulative (a deep insult to the audience – in my never-humble-opinion), but it makes it difficult to follow the dialogue in the movie. I usually have to wait to see movies till I can buy them and watch them with subtitles. If the soundtrack is particularly emotionally manipulative, I’ve been known to turn the subtitles on and watch the movie on mute – a much more satisfying experience!

In social situations, I often rely on partial lip-reading: it helps me make more sense of the sounds. (And, yes – that is one reason why I hate the cultural normalization of niqabs and burkas.)

Well, that is my best advice for how to improve your son’s comprehension. As to speaking fast and mumbling…

If I knew how to stop my sons (13 and 18 now) from speaking very fast and mumbling, I’d try it – because they both do.

I’ve tried to get them to recite poetry in order to get them to improve the cadence of their speech – but they are about as interested in reciting poetry as I am in learning to sing movie scores… (Many of us Aspies have a deep-rooted hate for pretentiousness – and let’s face it, much poetry is very, very pretentious.)

In grade 9, my older son took drama in school – that did help him learn to speak slowly and understandably. Now, when he remembers to do so, he uses that skill.

Another thing which has helped them was talking to their grandmothers: one has a hearing problem and does not tolerate hearing aids well, the other struggles with English. So when they speak to either one of them, they have to consider not just what they want to convey, but also how best to convey it. They have to tailor their words differently for each grandmother – which forces them to pay attention to their diction.

It is surprising how helping other people overcome their difficulties can be an excellent tool for Aspies to help themselves overcome their own ‘little things’!!!    ;0)

I wish I could be of more help…

If anyone ‘out there’ has better suggestions, please, comment and let us all know.

Muslim Brotherhood in America – the course

It is difficult to understand the impact of much of the news we hear if we lack the context in which to evaluate it.  While I have educated myself on Islam and even early Middle Eastern history in order to better understand the cultural context which gave rise to this major world religion.

Still, this does not mean that I understand all the intricacies of the modern network of Muslim organizations.  Without understanding this, how can I recognize the difference between truly moderate Muslim voices (whom we need to help be heard) and shameless fronts for Islamists?

The ‘litmus test’ I usually use is ‘Sharia’:  Muslims who have attempted to escape Sharia tend to be moderate voices of reason while Muslims who support Sharia, by definition, wish to impose their religious views onto their neighbors….  This may be a good ‘rule of thumb’, but it does not help me understand the complexities of the various Muslim organizations in North America.

Here is something that might help get one started:  a 10-part course about the history and activities of Muslim Brotherhood in America.

Anti-Piracy Patent Stops Students From Sharing Textbooks

If you went to University or College before electronic textbooks were a reality, chances are you bought at least some of your textbooks second-hand – or, perhaps, sold the ones you were done with in order to buy new ones.  Textbooks are hundreds of dollars!

One could understand that:  with a small target audience, the printing setup costs would drive the prices of individual books sky high!

Electronic textbooks are an excellent way to make education more accessible.  Everyone should be happy about that!!!

Well, sot so.

‘The result is less money for publishers, and fewer opportunities for professors like himself[Joseph Henry Vogel] to get published. With Vogel’s invention, however, this threat can be stopped.

The idea is simple. As part of a course, students will have to participate in a web-based discussion board, an activity which counts towards their final grade. To gain access to the board students need a special code, which they get by buying the associated textbook.

Students who don’t pay can’t participate in the course and therefore get a lower grade.’

In other words, when you register for the course, you only get access to part of it.  To access the full course, you also have to buy the textbook.  New.

Scum!!!
