About This Chapter

As you study for the PECT PAPA exam, use these lessons to help you better understand the statistical analyses of data and different ways for presenting statistical results.

PECT PAPA: Data & Statistics - Chapter Summary

This chapter can help you study basic statistical analysis and how the results can be presented as part of your review for the PECT PAPA exam's mathematics module. Watch our expert instructors in this series of lesson videos to review:

  • Calculations for measures of central tendency and range
  • Types of frequency distributions
  • Analyzing and making predictions for categorical data
  • Using histograms, circle graphs, line graphs and tables
  • Formulas used to find percentiles

After reviewing these lessons, take the quizzes that accompany them and then use the results to identify topics you don't fully understand. You can then use the video tags to return to the videos and improve your understanding of the material while skipping of the subjects you've already mastered. When you think you have a firm understanding of the material, make sure you are ready to move on and take the practice chapter exam to test your overall understanding of the material.

Center, shape, and spread are all words that describe what a particular graph looks like. Watch this video lesson to see how you can identify and explain each.

Statistical Analysis with Categorical Data

3. Statistical Analysis with Categorical Data

Learn why percentages are so important when analyzing categorical data in this video lesson. Watch as the data is turned into a data table and a visual bar graph as ways to analyze the data.

Make Estimates and Predictions from Categorical Data

4. Make Estimates and Predictions from Categorical Data

Categorical data can be estimated but not predicted. Learn why in this video lesson along with how to read and gather information from a bar graph of categorical data.

What is a Histogram in Math? - Definition & Examples

5. What is a Histogram in Math? - Definition & Examples

Watch this video lesson to see how useful a histogram can be when you need to show a bunch of data in an easy to read format. Also, learn how you can easily gather the information you need from looking at a histogram.

Circle Graph: Definition & Examples

6. Circle Graph: Definition & Examples

A circle graph is a circular chart divided into sections that each represent a percentage of the total. This lesson will define a circle graph and give some examples of types of circle graphs.

Reading and Interpreting Line Graphs

7. Reading and Interpreting Line Graphs
