Outline of course content

  • Experimental Design - Why randomized controls are key. What the possible confounders in observational studies are.
  • Descriptive Statistics - mean, median, SD, histograms, normal curve, etc.
  • Linear Regression - correlation coefficient, regression equation, etc.
  • Probability
  • Statistics for Chance Numbers - expected value and Standard error of chance processes, probability histograms and convergence to normal curve. Focus is on developing simple chance models (box models- drawing numbers at random from a box) that more complicated sampling processes can be translated into.
  • Sampling and Statistical Inference - Using sample means and percents to estimate population means and proportions, and attaching margins of errors to our estimates by computing confidence intervals. Why randomized sampling is key.
  • Hypothiesis Tests-one sample and two sample Z-tests, t-tests and chi-square tests for goodness of fit and independence. Focus is on understanding how these tests depend on chance models
  • Limits of Significance Tests- understanding what the P-value means and under what circumstances it is valid (for example, hypotheses must be stated before looking at the data, the total number of experiments before significant results were found must be reported, etc.)

    Grade for required work

    3 Exams (each worth 20 % ): 60 %
    Homework: 15%
    Final Exam :   25%

    Bonus Points-You may earn between 0 and 100 Bonus Points.

    Every Bonus Point earned helps your overall grade, but even if you do no Bonus Work, you can still get 100% for the course. In other words, bonus points can only help you. Bonus points are extra credit. Bonus points are awarded for:
    1. iClicker Points-- 25 pts.
      There will be 2 types of clicker questions:
      1. Participatory Discussion Questions where you get credit just for answering the question.
      2. Combined participation/graded questions which are 50% participation, 50% correct answer.
      There are 29 classes, each worth 1 bonus point. Your 4 lowest bonus scores are dropped. In other words, you can miss up to 4 classes and still score the maximum 25 points.
    2. Pre-Lecture bonus points-- 25 pts.
      Each class there will be a short pre-lecture videos posted on Lon Capa followed by a few questions. The pre-lectures are designed to give you a preview of the basic concepts you'll see in the actual lectures. Pre-lectures are due by 11:59 pm the day of the lecture allowing students who would prefer to see the lecture first a chance to do so.
    3. Dropped homework bonus points-- 10 pts.
      10 percent points are added to everyone's homework. If this puts your hw average over 100%, the extra points count as bonus points. For example, if you have a 98% on the homework, 98% + 10% =108%, so your hw score =100% and you get 8 bonus points.
    4. Lon Capa Surveys--10 pts.
      There will be 5 surveys due on the first Friday of each month (see calendar). Each survey is worth 2 Bonus pts.
      The surveys are all anonymous. Lon Capa just records whether or not you submitted a survey, not who submitted which answer. You must answer every question on the survey to get the 5pts.
    5. Completed Notebook--15 pts.
      The Completed Notebook is worth 15 bonus pts.
      You get 15 points if you have all the WHITE pages filled in. You may skip ALL the colored pages and summary pages.
      We'll look over your notebooks at the final and if the lectures are filled in you'll receive all 15 bonus points. If you're missing more than 3 white pages don't bother to turn in the notebook b/c you'll get a 0. So go to Lectures and fill in your missing pages if you want the 15 points.
    6. Bonus points can only help you. You can still get 100% without doing any bonus work. Bonus points are figured into your grade as follows:

      (Percentage on Required Work) + ( Percentage on Bonus Points)/4
      100 + (Percentage on Bonus Points)/4

      Suppose at the end of the semester you have a 75% average and you did 100% of the bonus work.

      100/4 = 25, so add 25 to the numerator and denominator to get:

      (75 + 25)/ (100 + 25) = 100/125= 80.
      So your grade would be raised from a 75% to an 80%.

      Overall Grade is Translated into a Letter Grade as follows:

      A+ 97-100 A 93-96.99 A- 90-92.99
      B+ 87-89.99 B 83-86.99 B- 80-82.99
      C+ 77-79.99 C 73-76.99 C- 70-72.99
      D+ 67-69.99 D 63-66.99 D- 60-62.99
      F < 59.99
