### About This Chapter

## 6th-8th Grade Math: Statistics - Chapter Summary

The video lessons in this chapter on statistics are designed to help reinforce the material your middle school student is learning in class. The videos keep things simple and fun as they review topics such as types of sample groups, the various ways statistics can be grouped in terms of mean, median, mode and range and how to interpret these measurements and quartiles on tables and graphs.

Subject matter experts can help answer any questions that arise. Use the short, multiple-choice quizzes after each lesson and the chapter exam to confirm your 6th-8th grader's grasp of statistics and find any gaps in comprehension that need further clarification. You can view the video lessons as many times as needed and you can easily jump between subjects therein.

## Chapter Lessons and Objectives

Video | Objective |
---|---|

How to Calculate Mean, Median, Mode & Range | Students will learn the difference between mean, median, mode and range and how to calculate them. |

Samples: Representative, Random & Biased | With this lesson, students will be able to tell the difference between types of sample groups and explain their significance. |

Finding Mean, Median & Mode on a Frequency Table | Following this lesson, students will be able to demonstrate their ability to identify mean, median and mode on a table. |

Statistical vs Non-Statistical Questions | Students will be able to identify statistical and non-statistical questions and provide examples of each. |

Calculating & Interpreting Quartiles | This lesson will enable students to demonstrate the ability to calculate and interpret quartiles. |

### 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.

### 2. Samples: Representative, Random & Biased

When conducting statistical research, a great deal of importance hinges on the type of sample you use. In this lesson, we will learn about representative, random, and biased samples, as well as which is best for what situation.

### 3. Finding Mean, Median & Mode on a Frequency Table

Many times when you are dealing with statistical data it will be presented in the form of a frequency table. As you'll see in this lesson, frequency tables often take much of the hard work out of analyzing a data set.

### 4. Statistical vs Non-Statistical Questions

Watch this video lesson and you will learn how to spot statistical and non-statistical questions. You will learn that statistical questions have variance in their answers while non-statistical questions don't.

### 5. Calculating & Interpreting Quartiles

If you're going to divide a data set into four groups in order to make a box and whisker plot, then it would likely be very helpful to know where to split the data. Quartiles tell you exactly where to make the divisions.
