##### What You Will Learn

**Use of Statistics**

- Examine who really uses statistics
- Examine how statistics is used
- Provide a very short history of the use of statistics
- Introduction and basic use of statistical software

**Grouping and Displaying Data to Convey Meaning**

- Show the difference between samples and populations
- Convert raw data to useful information
- Construct and use frequency distributions
- Graph frequency distributions
- Use frequency distributions to make decisions

**Measures of Central Tendency and Dispersion in Frequency Distributions**

- Use summary statistics to describe collections of data
- Use the mean, median, and mode to describe how data "bunch up"
- Use the range, variance, and standard deviation to describe how data "spread out"
- Examine computer-based exploratory data analysis to see other useful ways to summarize data

**Probability: Introductory Ideas**

- Examine the use of probability theory in decision making
- Explain the different ways probabilities arise
- Develop rules for calculating different kinds of probabilities

**Probability Distributions**

- Introduce the probability distributions most commonly used in decision making
- Use the concept of expected value to make decisions
- Show which probability distribution to use and how to find its values
- Understand the limitations of each of the probability distributions used

**Sampling and Statistical Distributions**

- Take a sample from an entire population and use it to describe the population
- Random Sampling Techniques
- Approximating binomial distributions with normal distributions
