Statistical Studies 2/4/2016

mmmm....

Sam is not here, so be nice to your sub. Record your Feltron data and work on the seven Statistical Studies exercises on Khan Academy.

If you finish, please don't become a disturbance. It would be rude, and people would judge you.

You can: do work for another class, or work on review on Khan Academy. If you want more statistics, read this amazing book, Statistics Done Wrong.

Of course, you may not finish in class, in which case just finish it for homework. Or rather, spend an hour at home, and if you don't finish, let me know. Also, if you are struggling, you can email me questions, but be specific.

Please do work. Please don't distract your classmates. If you're done, offer help; if you're having trouble, ask for help!

Sam, Kahn Academy is not working for Statistical Studies as many questions are confusingly worded and getting one wrong sets you back to the beginning. I am very frustrated with this and it is hard to continue with such cruel crushing practices.

Feltron Variables - Monday 2/1/2015

Do you have your tickets... to the gun show? #flexin #doyouevenliftbro Please complete this to show you did your homework: Loading... So, let's talk about what makes this project hard: actually collecting data. It's not hard, but somehow, doing it every day is hard. It's easy to miss a day... then two... then all the sudden, you have missed a bunch, and it's scary and you don't want to think about it, so you don't do it. So we are going to preempt all that by putting some work in today to make it hard to forget. First, we will make a Google form. I started it for you, all you is copy it and add your 4 variables . Once you have that, you are going to use a cool feature of Google Sheets to have google email you this form every day. The form will be in the email itself, so all you have to do is open the email, fill out the form, and hit enter. Here are the instructions to follow . Don't be intimidated! You just have to copy and paste some cod...

Monday 9/28

9/28/15 Monday Check in: Friday class & Homework Classwork: As long as we’re talking climate change... If someone tells you they don’t believe humans are causing it, you might want to ask them if smoking is bad for you. Why? There is as much evidence that humans are causing global warming as there is evidence that smoking causes cancer (you don’t have to click that link, I just like to put it up). Anyway, here’s a chart: It is entitled “Breakdown of the anthropic greenhouse gas emissions by gas, in billion tons carbon equivalent, in 2004” - it is a breakdown of the greenhouse gases emitted in 2004 that humans are responsible for. What’s the biggest greenhouse gas? What’s all that CO2 doing, and where does it go? A lot of it goes into the ocean, which seems better than the air, and it is... up to a point. The more CO2 in the ocean, the more acidic it gets (And the more acidic it gets, the lower its ph gets). That is fine... until it’s not. At some...

First day links

Review of what we did in class: The survey found in the post below this one. Stay or Switch, the Monty Hall Problem - played with this and became familiar with it. The Monty Hall Problem is from The Monty Hall show (weird, right?). The show is from the 1950's, but the problem and its answer are from 1990. Here is a link to Marilyn Vos Savant's page, and her solution to the problem, that resulted in a bunch of condescending, chauvinist responses from male math professors. Homework: Conditional Probability - For homework, be able to describe - in plain language - what all the sliders do on this. For example, the first slider changes the size of the red platform, so less of the balls hit it. You don't need to write anything, just play around with it and get a feel for it, but don't worry about what it says, it looks complicated and intimidating. You don't have to read it, just play with the interactive animation. Great first class!
