Frailing Banjo, Clawhammer Guitar, Travis Picking And More

I don’t own a banjo, but it figures prominently in a lot of music I like. Found this guy’s instruction style to be interesting.

Now, that first guy has a lot of enthusiasm, and correctly goes over everything slow and methodically, which I like for the first hour of watching. But, now, I like this guy’s style, too, moving on to how to apply it to guitar. What I like about this, is he plays an introduction that is just full of different ways to incorporate what he’s about to teach you, which makes it immediately reach out and grab you before getting into the how of it.

And on from there. So many good examples of different picking in this play list that I had to share.

Analyzing Poll Data, and Critical Thinking

I’ve regretted taking statistics pass/fail, and then quit going to class once I’d passed enough tests to devote my time to the other coursework I had to finish up and graduate. I confess, at that point I just wanted out of what seemed like a trap in an academic lifestyle I couldn’t afford, and wasn’t so much into learning.

So, here’s someone who seems to have a pretty firm grasp on taking on statistical analysis.

Also, as a sort of link dump, here’s an article on critical thinking I came across.

Polls, Bias, And Logical Fallacy: When Did You Stop Beating Your Wife?

I’m playing catch up here, trying to find the articles I read before this was a subject worth jotting a few notes down about.

Bad poll questions, sloppy media interpretations

“We decided to develop a general panel called the Angus Reid Forum,” Angus says. “It’s got about 150,000 members.”…“We pay people to do surveys—they get from fifty cents to five dollars per survey,”

Angus Reid Strategies, one of the largest Canadian-owned polling companies (and newly subsumed under Vision Critical), now conducts the bulk of its research online, culling respondents for specific polls from an Internet forum of tens of thousands of willing Canadians. But Frank Graves, head of competitor EKOS Research Associates, suggests that this method results in some self-selection bias.

Terms that came up in looking this over.

Confirmation Bias
False Paradox
selection bias.

sampling bias
false dilemna
false precision

Interesting that a democrat polling group was ranked highest in an election where a democrat won. As much as they’ll swear up and down they are unbiased, I suggest they know they are influential, and the very nature of their polling leads to biased results.

“Fordham University has published a ranking of the most accurate pollsters of the 2012 in terms of national trends, and (both) top spots were held by Democratic-leaning Public Policy Polling, the North Carolina-based firm.”
