# Ch 1: Common Core Math Grade 6 - Statistics & Probability: Statistical Variability

This chapter provides useful resources to help you meet the Common Core State Standards in math. Use the engaging lesson videos and practice quizzes to teach your sixth graders about statistical variability.

Standard: Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. For example, 'How old am I?' is not a statistical question, but 'How old are the students in my school?' is a statistical question because one anticipates variability in students' ages. (CCSS.MATH.CONTENT.6.SP.A.1)

Standard:Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape. (CCSS.MATH.CONTENT.6.SP.A.2)

Standard: Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number. (CCSS.MATH.CONTENT.6.SP.A.3)

When students grasp statistical variability, they'll be able to recognize statistical questions and understand the distribution of data sets used to answer statistical questions. Use the resources in this chapter to help students learn the following concepts:

• Difference between statistical and non-statistical questions
• Finding the center in a data set
• Measures of central tendency in data sets
• Visual representations of data sets
• Unimodal and bimodal distributions
• Spread in data sets
• Quartiles and interquartile range
• Population and sample variance

Students who have achieved mastery of these standards will understand that a statistical question anticipates variability in the data needed to answer it. They ill know how to describe distributions by center, spread and shape and understand what information is contained in measures of center and measures of variation in data sets.

### How to Use These Lessons in Your Classroom

Use the following tips to incorporate these resources materials into your teaching curriculum and meet Common Core Standards.

#### Brainstorm Statistical and Non-Statistical Questions

After watching the lesson 'Statistical vs Non-Statistical Questions,' work together as a class to brainstorm a list of both types of questions.

#### Create a Class Quiz

Watch the lessons on mean, median, mode and range. Use the practice problems in the lesson 'Calculating the Mean, Median, Mode & Range' as a jumping off point for students to create their own problems. Compile the questions, then assign as a class quiz.

#### Introduce Concepts With Lesson Videos

At the beginning of a new topic, show the class the lesson video as a brief introduction. Follow up with your own instruction and answer questions before beginning in-class assignments.
