• Four main topics of AP Statistics as stated by the College Board
• Exploratory analysis (describing data)
• Sampling and Experimentation (designing an experiment)
• Anticipating Patterns (probability)
• Statistical Inference (drawing conclusions from data)

• 1.3 – Data Analysis
• Descriptive Statistics
• Definition:Methods of collecting, organizing and summarizing data

• Examples:45% of High School seniors have a job

• Inferential Statistics
• Definition: Generalizing information from a sample to a population

• Examples:From a random sample of 20 CHS seniors it was found that 9 had a job, it is reasonable to believe that approximately 45% of CHS seniors have a job

• Population
• Definition:The entire collection of individuals or objects about which information is desired

• Examples:All seniors at Crosby High School

• Sample
• Definition:A subset of a population selected for study by a set method

• Examples:20 seniors from CHS selected at random

• 1.4 – types of data
• Variable
• Definition: Any characteristics that can change from one individual to another

• Examples:Weight, Height, Age, Number of siblings, etc….

• Categorical Data(or qualitative data)
• Definition:Data that is described by non-numeric values

• Examples:eye color, marital status, phone number (numbers can be qualitative if their selection is not sequential)

• Numerical Data (or quantitative data)
• Definition:Data that is described by numeric values

• Examples:age, weight, steps taken to kitchen

• Discrete Numerical Data
• Definition:Numeric data that can only be isolated points on a number line

• Examples:number of bathroom breaks taken, number of teeth

• Continuous Numerical Data
• Definition:Numeric data that can be any value within a range on a number line

• Examples:Age, weight, miles per gallon

• Bivariate and Multivariate Data
• Definition:Data that consist of multiple observations per individual

• Examples:height and weight, favorite color and gender

• 1.4 - Simple Graphical displays
• Frequency Distribution
• Definition:A table that displays frequencies of categorical data

• Examples:

• Bar Chart
• Definition:A graph of a
