How to Calculate Mean, Median, Mode & Range

1. How to Calculate Mean, Median, Mode & Range

Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.

Summarizing Categorical Data using Tables

2. Summarizing Categorical Data using Tables

Watch this video lesson to find out why data tables are an excellent way to summarize your categorical data. Learn what you need to do to your data before constructing a table and the two ways you can show your data.

Circle Graph: Definition & Examples

3. 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.

Creating & Interpreting Histograms: Process & Examples

4. 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.

Frequency Distributions: Definition & Types

5. 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.

Percentile Rank in Statistics: Definition & Formula

6. Percentile Rank in Statistics: Definition & Formula

In this lesson, you will learn to define percentile rank and learn how it is calculated. Following this lesson, you will have the opportunity to test your knowledge with a short quiz.

Spread in Data Sets: Definition & Example

7. Spread in Data Sets: Definition & Example

Identifying the spread in data sets is a very important part of statistics. You can do this several ways, but the most common methods are through range, interquartile range, and variance.

Creating & Interpreting Scatterplots: Process & Examples

8. Creating & Interpreting Scatterplots: Process & Examples

Scatterplots are a great visual representation of two sets of data. In this lesson, you will learn how to interpret bivariate data to create scatterplots and understand the relationship between the two variables.

Reading & Interpreting Pictographs

9. Reading & Interpreting Pictographs

Imagine reading chart after chart of the same dry information. Now imagine if that information could be presented with images and in only one chart. Much better, right? That's exactly what pictographs allow us to do.
