What is a Histogram in Math? - Definition & Examples

1. 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.

Creating & Interpreting Histograms: Process & Examples

2. 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 Box Plots: Process & Examples

3. Creating & Interpreting Box Plots: Process & Examples

Box plots are an essential tool in statistical analysis. This lesson will help you create a box plot and understand its meaning. When you are finished, test your understanding with a short quiz!

Understanding Bar Graphs and Pie Charts

4. 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.

Creating & Reading Stem & Leaf Displays

5. Creating & Reading Stem & Leaf Displays

Every once in a while you will come across stem-and-leaf displays in statistics. These displays can be very useful in identifying all of the values in a data set while still visually representing the data.

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.

Bar Graph: Definition, Types & Examples

7. Bar Graph: Definition, Types & Examples

A bar graph is a mathematical representation of data. In this lesson, you will learn the definition of a bar graph, including how to recognize the different types of bar graphs. You will also learn how to create bar graphs.

Double Bar Graph: Definition & Examples

8. Double Bar Graph: Definition & Examples

We will explore the function and examples of a double bar graph. Also in this lesson you will learn to create questions and interpret data from a double bar graph.

Mean, Median & Mode: Measures of Central Tendency

9. 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.

Calculating the Mean, Median, Mode & Range: Practice Problems

10. Calculating the Mean, Median, Mode & Range: Practice Problems

Calculating the mean, median, mode, and range of a data set is a fundamental part of learning statistics. Use this video to practice your skills and then test your knowledge with a short quiz.

Calculating Weighted Average: Method, Formula & Example

11. Calculating Weighted Average: Method, Formula & Example

This lesson will examine the concept of a weighted average and types of situations when it should be used instead of a standard average. It will also give some real-world examples of a weighted average.

Outlier in Statistics: Definition & Explanation

12. Outlier in Statistics: Definition & Explanation

An outlier is any value that is numerically distant from most of the other data points in a set of data. Learn about the sources of outliers, histograms, scatterplots, the number line, and more.
