### Lecture: Discrete Random Variables, Bernoulli, and Binomial

### Lecture: Addition Rule + Conditional Probability

*The conditional probability of an event B is the probability that the event will occur given that an event A has already occurred.*

### Lecture: Midterm 1 (CBTF) - No Class :)

### Lecture: Probability, Birthday Problem, and Control Flow

### Lecture: Introduction to Probability + Monty Hall

*Probability is the likelihood or chance of an event occurring. This begins a multi-week journey discovering probability and how to simulate probabilistic events.*

### Lecture: Algorithms to Solve Complex Problems

*An algorithm is a step-by-step, detailed set of instructions to solve a problem. An algorithm can be expressed as English sentences (usually as a numbered list) and is a great way to begin solving complex problems.*

### Lecture: Quartiles and Box Plots

*Just like histograms, box plots are used as a way to visually represent numerical data. They do this through selected percentiles which are given special names.*

### Lecture: Bar Graphs and Histograms

*Large tables of numbers can be difficult to interpret, no matter how organized they are. Sometimes it is much easier to interpret graphs than numbers.*

### Lecture: Grouping Data (pandas)

*A groupby operation involves some combination of splitting the object, applying a function, and combining the results. This can be used to group large amounts of data and compute operations on these groups.*

### Lecture: Boolean Logic and Conditionals

### Lecture: Measures of Center and Spread

*Parameters are numerical facts about the population. In this lecture, we will look at parameters such as the average (µ) and standard deviation (σ) of a list of numbers. Later, we will start talking about statistics. Statistics are estimates of parameters computed from a sample.*

### Lecture: Simpson's Paradox and Stratification

*Stratification is often called the "blocking of observational studies" and allows us to use stratification to further explore observational studies.*

### Lecture: Confounders and Observational Studies

*For years observational studies have shown that people who carry lighters are more likely to get lung cancer. However, this does not mean that carrying lighters causes you to get cancer. Smoking is an obvious confounder! If we weren’t sure about this, how can we determine whether it’s the lighters or the confounders or (maybe some combination of both) that is causing the lung cancer?*

### Lecture: Blocking and Conditionals

*Random assignment to treatment and control works best to make the groups as alike as possible. With enough subjects, random differences average out. But what do you do if you have a small sample? Blocking first, then randomizing ensures that the treatment and control group are balanced with regard to the variables blocked on. We can use conditionals in pandas to help us do this!*

### Lecture: Experimental Design and Row Selection (pandas)

*Does the death penalty have a deterrent effect? Is chocolate good for you? What causes breast cancer? All of these questions attempt to assign a cause to an effect. A careful examination of data can help shed light on questions like these.*

### Lecture: Data Science Tools

*Data, Science, and Tools all have meaning in their own, explore how one relates to another and how they all related to Data Science DISCOVERY!*

### Lecture: Welcome to Data Science Discovery

*The next BIG thing at Illinois is Data Science and it starts with Discovery!*
