Ch 33: Understanding Descriptive Statistics

About This Chapter

Utilize this chapter to spur your memory on descriptive statistics. With your favorite Internet-ready device, you can review key terms and formulas about statistical data sets from your own home or from any Wi-Fi location.

Understanding Descriptive Statistics - Chapter Summary

In this chapter, revisit descriptive statistics. Take a closer look at how statistics are displayed visually, and explore how different visual representations can be used. You can also brush up on major terms used for describing and analyzing data sets. At the end of this chapter, you should have developed the skills to do the following:

  • Define mode, median, and mean
  • Show the types of frequency distribution
  • Determine uses for bar graphs, pie charts, and line plots
  • Establish the union, intersection, overlap, disjoint, and subset of Venn Diagrams
  • Differentiate between histograms and dot plots
  • Outline data sets
  • Use formulas for identifying percentiles in a data set

The short videos in this chapter walk you through all the major aspects of a descriptive statistics, including terminology, definitions, practical applications, and examples. Our video lessons come equipped with a timeline feature, allowing you to quickly jump to specific topics or concepts Each video lesson also comes with a full written transcript, which you can use to quickly scan for key vocabulary, terms, and formulas.

Mean, Median & Mode: Measures of Central Tendency

1. Mean, Median & Mode: Measures of Central Tendency

By describing the data using central tendency, a researcher and reader can understand what the typical score looks like. In this lesson, we will explore in more detail these measures of central tendency and how they relate to samples and populations.

Frequency Distributions: Definition & Types

2. Frequency Distributions: Definition & Types

This lesson explores the process of creating frequency distributions and histograms to give readers of your future scientific articles a numerical or visual way to understand the data you have presented.

Understanding Bar Graphs and Pie Charts

3. Understanding Bar Graphs and Pie Charts

In this lesson, we will examine two of the most widely used types of graphs: bar graphs and pie charts. These two graphs can provide the reader with a comparison of the different data that is displayed.

What is a Line Plot in Math? - Definition & Examples

4. What is a Line Plot in Math? - Definition & Examples

In this lesson, we will explore the functions and examples of a line plot. Also in this lesson, we will learn to create a line plot, create questions, and interpret data from a line plot.

Venn Diagrams: Subset, Disjoint, Overlap, Intersection & Union

5. Venn Diagrams: Subset, Disjoint, Overlap, Intersection & Union

The Venn diagram was introduced by John Venn. Yes, the Venn diagram is named after a real person! His idea was to show sets in terms of pictures. The Venn diagram is now used in many fields, including mathematics. Let's take a look at John Venn's idea.

Creating & Interpreting Histograms: Process & Examples

6. Creating & Interpreting Histograms: Process & Examples

Creating histograms can help you easily identify and interpret data. This lesson will give you several examples to better understand histograms and how to create them.

Creating & Interpreting Dot Plots: Process & Examples

7. Creating & Interpreting Dot Plots: Process & Examples

Dot plots are a visual way to display the frequency distribution in a data set. In this lesson, you will learn how to construct a dot plot and understand its uses.

Data Set in Math: Definition & Examples

8. Data Set in Math: Definition & Examples

In this lesson, learn about data sets and how to use the operations of mean, median, and mode to manipulate the data. Then, test your knowledge with a brief quiz.

Finding Percentiles in a Data Set: Formula & Examples

9. Finding Percentiles in a Data Set: Formula & Examples

Percentiles are often used in academics to compare student scores. Finding percentiles in a data set can be a useful way to organize and compare numbers in a data set.
