Or you can stop by office hours and get help in person.
Homework Schedule

Homework is due every Monday and Wednesday at 11:59pm (see calendar) on Lon-Capa. Ask questions on Lon Capa discussion boards and if you need more help, don't hestitate to come to the office hours in 23 Illini Hall.

(No late hw accepted but lowest 3 hw scores dropped)

Exam Schedule There will be 2 evening exams and a Final. See Exam Schedule for dates, times and locations.

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 < 60
Bonus Work

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

Everyone 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 (100 total bonus points):
1. Pre-Lecture Bonus problems --30 bonus points
2. Completed Notebook --30 bonus points
3. Lon Capa Surveys--20 bonus points
4. R Bonus Problems --20 bonus points

Descriptions
Pre-Lecture bonus points
There will be 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.
Completed Notebook
We will look over your notebook at the final. You'll get full credit if you have all the pages from lecture filled in.
Here's a list of the pages you may skip: All summary pages, 22-27, bottom of 58, 69, 96-104, 110, 147, 158, 169 and 195.
All the other pages are required. If you're missing more than 3 of the required pages don't bother to turn in the notebook because you won't receive any points. You may pick up your notebook at the end of your final to keep forever.

Here's the filled in notes for the pages you were supposed to complete on your own for bonus points.

Lon Capa Surveys
There will be 4 surveys due on the first Friday of each month (see the course calendar). Each survey is worth 5 bonus points. 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 5 points.
R Bonus Problems
There will be 5 Bonus Assignments on Lon Capa to help give you an introduction to the statistical computing language, R. They do not require having any previous programming experience.

*Bonus points can only help you. You can still get 100% in this class without doing any bonus work.
Bonus points are figured into your grade as follows:


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



So your grade would be raised from a 75% (C) to an 80% (B-).

Couse Outline

Study Design - observational studies vs. randomized experiments, why randomized controls are key, what the possible confounders in observational studies are.

Descriptive Statistics - mean, median, SD, histograms, box plots, normal curve, etc.

Probability - multiplication rule, addition rule, conditional probability, Bayes rule

Statistics for Random Variables - 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.

Significance Tests - one sample and two sample Z-tests and t-tests and chi-square tests for goodness of fit and independence. Focus is on understanding how these tests depend on chance models.

Experimental Power - Type I and II errors and the Power of Significance tests.

ANOVA for Comparing Group Means

Simple Linear Regression - correlation coefficient, regression equation, etc.

Inference for Simple Linear Regression - Understanding the Simple Linear Model and Assumptions, Confidence Intervals and Significance tests for the Slope, Analysis of Variance for regression, etc.

Binary Variables in Multiple Linear Regression - Causal Inference, Controlling for likely Confounders by including them as covariates in the regression model. Interactions between Binary and Quantitative variables . Models with 2 binary predictors.

Multiple Regression with Quantitative X's - 3-D scatter plots and interpreting slopes graphically, Interactions, F-tests for overall regression effect and t-tests for slopes.

Re-randomization Methods - Randomization Tests to calculate p-values for ANOVA and regression.

Transformation of Variables- Fitting a Linear Model to non-linear data, log and square root transformations

Logistic Regression -The log odds equation, making predictions and interpreting the slopes, the odds ratio, multiple logistic regression, maximum likelihood methods to estimate the slopes.

Non-Parametric Statistics- Transform data into ranks to compute p-v values using Wilcoxon Mann-Whitney test (rank sum or U stat), Kruskal-Wallis test and Spearman's Rank-Order Correlation Coefficient
