# Ch 45: Praxis Mathematics: Statistics

This review chapter will have you ready for questions about statistics on the Praxis Mathematics content knowledge test. Our expert instructors, video lessons and practice quizzes are exactly what you need.

## Praxis Mathematics: Statistics - Chapter Summary

Many States use the Praxis Mathematics Content Knowledge test for teacher certification or endorsement. If you're planning to take this test but are feeling a little rusty on the subject of statistics, look no further. We can help! Our chapter on statistics contains video lessons, both brief and thorough, created by our instructors who are experts in math and education.

Give your brain a break from boring lectures or the drudgery of textbook reading. Our videos are engaging, easy to navigate and very accessible. Watch them on any mobile device. You might even observe some teaching techniques you like enough to incorporate them into your teaching someday. Our instructors will lead you through reviewing topics including, but not limited to:

• Descriptive vs inferential statistics
• Simple random sampling
• Measures of central tendency (mean, mode, median, etc) and distribution
• Quantitative data
• Analysis of data sets
• Population and sample variance
• Bar graphs, pie charts, frequency tables, histograms, dot & box plots, scatterplots
• Interpreting slope, intercept, correlations, frequencies, regression and more

These animated lessons are short and they can be viewed in any sequence according to your existing knowledge. Don't skip over the lesson quizzes. They will give you a good idea of how well prepared you are for the test.

### Objectives for the Praxis Math: Statistics Chapter

Several States use the Praxis Math test. Double check that your state is one of them and then let us help you review statistics in preparation. The computer-based multiple-choice test of 60 questions is divided into 2 content categories. With content that reflects this chapter's topics, the second category, Geometry, Probability, Statistics and Discrete Mathematics, accounts for 32% of the test.

Specifically, you could encounter questions that assess your ability to interpret data collected from measurements on single as well as multiple variables, categorically or quantitatively; use dot plots, histograms and box plots; calculate and interpret measures of central tendency and spread; fit deviation to a normal distribution to estimate population percentages; and create and interpret two-way frequency tables and scatterplots. You could also demonstrate your ability to solve problems using linear regression models in terms of rate of change; work with intercepts and correlations; understand the inferential nature of statistics regarding population parameters; and use simulation and inferences in data-gathering and interpretation. Our lessons will correlate and expound upon these test objectives.
