# Ch 35: Measuring & Displaying Data

This chapter can teach you about measurement scales and the various ways of interpreting, organizing and displaying quantitative data. Use these video lessons and online tests to understand and utilize descriptive statistics.

## Measuring & Displaying Data - Chapter Summary

This chapter's comprehensive lessons teach you how to choose and use an appropriate measurement scale to answer research questions and analyze data. A variety of formats for displaying data are covered, including tables, pie charts and histograms. You'll look at the measures of central tendency, such as mean, median and mode, as well as learning the difference between mean and median. Dispersion, which includes range and standard deviation, is also included in this chapter. A practice lesson will give you a chance to use what you've studied in calculating mean, median, mode and range.

Another lesson covers the application of linear transformations, such as stretching and shrinking, and describes the effect of these transformations on measures of central tendency and dispersion. You'll learn about standard deviation and shifts in the mean. By the end of this chapter's lessons, you'll have a solid understanding of topics that include:

• Quantitative data
• Meaning of nominal, ordinal, interval and ratio
• Creating and interpreting histograms
• Dot plots and box plots
• Calculating mean, median, mode and ratio
• Spread, shape, symmetry and skewness in data sets
• Maximums, minimums and outliers
• Quartiles and the interquartile range

Expert instructors guide you through each topic, using examples from the real world to make their points. Written transcripts of the lessons accompany the videos, giving you access to this material in two formats. You can test what you've learned with the multiple-choice quizzes at the end of each lesson. The questions contain links that lead back to key points and passages, making it easy to review material without re-watching the lesson in its entirety.
