Class Topics: 08.22.14

In Common Core Math Six today, Mr. Giomini briefly reviewed last night's Evening Practice at the beginning of class.  Using Chromebooks or mobile devices, students completed a Socrative quiz that helped reinforced last night's concepts that were assigned for Evening Practice: population, sample, and statistical questioning.

Mr. Giomini then introduced and modeled Lesson 1.2: Mean, Median, Mode, and Range.  The terms measure of central tendency and measure of spread were defined.  Students then worked with the example below to help practice the skill:

The ages of the participants in a mountain bike race are:

 14, 23, 20, 24, 17, 21, 31, 27, 25, 14, 28, and 45. 

1. Find the mean, median, and mode of the ages.
2. Which measure of central tendency best represents the ages of the participants?  Explain your reasoning.

Today's Learning Targets: The student will be able to...

• determine the mean, median, mode, and range when given a data set.  
• recognize that a measure of central tendency for a numerical data set summarizes all of its values with a single number, while a measure of spread describes how its values vary with a single number.

For Weekend Practice, the student is expected to...

• complete pages seven and eight in their Chapter One handout.
• complete the Khan Skill: Statistical Questions.  

Statistics intro: Mean, median and mode: This is a fantastic intro to the basics of statistics. Our focus here is to help you understand the core concepts of arithmetic mean, median, and mode.
