Exploratory Data Analysis

Exploratory data analysis (EDA) is a crucial aspect of statistics, involving techniques for exploring and summarizing data to identify patterns, trends, and potential outliers. Students need to be familiar with methods like:

Stem-and-leaf plots
Box plots
Scatterplots
Histograms
Measures of central tendency and variability (mean, median, standard deviation)

Probability

Probability theory is a fundamental concept in statistics, providing a framework for understanding the likelihood of events occurring. Key topics include:

Sample spaces and events
Probability rules (addition and multiplication rules)
Conditional probability and independence
Bayes’ theorem

Sampling Distributions

Sampling distributions are central to statistical inference, representing the distribution of a statistic (e.g., sample mean) based on repeated sampling from a population. Students should understand:

Central Limit Theorem
Properties of sampling distributions (mean, variance)
Confidence intervals and hypothesis testing

Hypothesis Testing

Hypothesis testing is a statistical procedure used to determine whether there is sufficient evidence to reject a null hypothesis. Key concepts include:

Null and alternative hypotheses
Type I and Type II errors
p-values and critical values
One-sample and two-sample tests (e.g., t-tests, z-tests)

Correlation and Regression, Ap stats test 5b answer key

Correlation and regression analysis examine the relationship between variables. Students should be familiar with:

Pearson correlation coefficient
Scatterplots and regression lines
Simple linear regression (estimating and interpreting slope and intercept)
Correlation does not imply causation
