# Ch 12: Praxis I Math: Basic Statistics and Probability

Allow us to help you prepare for the Praxis I Math exam. We provide video lessons covering basic statistics and probability. You can also check your knowledge with our self-assessment quizzes.

## Praxis I Math: Basic Statistics and Probability

This chapter is intended to help you learn about statistical variability, distributions, either/or probability, standard deviation and shifts in the mean. Other lesson topics you'll learn about related to basic statistics and probability include:

• Using random samplings to draw inferences about a population
• Investigating chance processes
• Evaluating and understanding random processes underlying statistical experiments
• Developing and using probability models
• Calculating simple conditional probabilities
• Probability of independent and dependent events
• Learning the 'At Least One' Rule
• Probability of simple, compound and complementary events
• Using probability to evaluate outcomes of decisions
• Understanding patterns of association in bi-variate data

Each lesson will be thoroughly explained by your video instructors as they show you how what you're learning can be used on the actual exam. The different learning approaches used throughout lessons are a way to keep them interesting and to ensure that you're ready for the exam.

### Objectives of the Basic Statistics and Probability Course

The chapter is designed to help you specifically with the data analysis and probability section of the Praxis, which is about 25% of the entire exam. You'll have a better idea of how to answer questions on the actual exam once you've completed this lesson's self-assessment quizzes in addition to seeing how much you've learned about basic statistics and probability.

The math test will measure the mathematical skills and ideas that an adult with a degree might need in addition to testing how well you can reason in a quantitative context and solve problems. There are about 12 multiple choice questions on the Praxis I Math test about data analysis and probability. You'll have 75 minutes to complete all 46 questions on the exam, but calculators are not allowed for the exam.
