Session 1: Mean
Motivational Moment: Play
The teacher will play a motivational video before the start of the formal lesson to inspire their students to work together. The teacher will explain that a few people working together will form a small group, which could lead to a large group working together. You may not succeed the first time but keep trying. Many of our assignments may involve individual work, small group and large groups to complete a task, but together will reach the common goal or outcome.
Materials:
- PowerPoint Presentation
- Smartboard or Projector
- Pencil
- Paper
- Calculator
Teachers inform students what they believe should go into their notebook while teaching the lesson.
Standards
- SP.A.2 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.
- SP.A.3 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. (Miles & Williams, 2016)
Interpretation (What do students need to know and be able to do?) of standard for this lesson plan:
- Understand that data collected to answer a statistical question can be analyzed by their distribution.
- Calculate mean.
- Describe a set of data using its center (mean, median, and mode), spread (range), and overall shape.
- Create a line plot, histogram, and a box plot. (Miles & Williams, 2016)
Objective:
- Student will be able to understand that data generated from statistical questions vary IOT 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.
- Student will be able to identify the differences between a statistical and no-statistical question IOT 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.

- How can you find the mean value of a data set?
Activity/Task
Warmup:
The teacher will explain data generated from statistical questions will vary and data from a non-statistical question will have a set answer? Students will determine whether the questions below are statistical or non-statistical and then have a discussion with their group and form group consciences:

- Mean: the value obtained by dividing the sum of several quantities by the number; an average.
- Average: a number expressing the central or typical value in a data set, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their data number.
- Outlier: something that lies outside the main set of data.
Background Information:

Mr. & Mrs. Steve Fred has invested their business into the community and people supporting their business. The Fred’s provide fundraising activities to various organizations and schools. The Fred’s host their annual Christmas party for the students of parents of Tilden Middle school were their guests eat a delightful dinner and are showered with gifts from V & S bowling lanes. Mr. & Mrs. Fred host Jimmy’s Juniors Youth Bowling League where bowlers have mentors, which teaches and inspires youth from ages 6-18 in the sport of bowling, friendship, sportsmanship, and life.

50, 60, 70, 70, 100
My outlier is 100.
50+ 60+ 70+ 70+ 100= 350 350 ./. 5 = 70
My mean is 70
Large/Small Group Instruction:

The teacher will provide time for students in their flexible groups and the teacher to discuss and present their answers to the class. Students in their flexible groups and the teacher will work together to solve the problem below:
Family & Friends Day at V & Elmwood Lanes
You and a friend bowled four-game each and your scores are as follows: 70, 60, 60, 65, 80, 90, 40, 110. What is your outlier? What is the mean? What is the mean without the outlier?
40, 60, 60, 65, 70, 80, 90, 110
Our outliers are 40 and 100.
40 +60 + 60 + 65 + 70 + 80 + 90 + 110 = 575 ./. 8 =71.88
Our mean is 71.88 with the outliers.
60 + 60 + 65 + 70 + 80 + 90 = 425 ./. 6 = 70.83
Our mean is 71.88 without the outliers.
