Quiz on Distributions and the Empirical Rule - Section 2: Poster Scavenger Hunt

Teenagers are highly motivated by peer review. Creating posters that will be displayed for other students to observe and critique is a great opportunity to maximize this motivation and seize the chance to improve their peer review skills. In the Scavenger Hunt, I ask students to focus on finding posters that display specific types of information (normal curve, mean and median comparisons, standard deviation, right-skew, etc). Once all the students have completed the scavenger hunt we can engage in a discussion of what makes one poster better than another. After they have already ‘used’ the posters to answer questions their evaluations tend to reveal that a good poster is clearly organized, accurately labeled, and includes summaries that are clear and written in a language that is easy to interpret. This process of self-assessment is worth far more than my best rubric.

# Quiz on Distributions and the Empirical Rule

Lesson 6 of 13

## Objective: SWBAT demonstrate their ability to describe a one-variable distribution and use the Empirical Rule to predict population percentages from appropriate distributions.

## Big Idea: This quiz is an opportunity to demonstrate your understanding of one-variable distributions and the Empirical Rule.

Students will use the majority of this class period to demonstrate their understanding of one-variable distributions and the normal model on Univariate Statistics Quiz. This quiz asks students to describe the shape, center and spread of various distributions, calculate the standard deviation of a data set, and use the Empirical Rule [MP4, MP5].

When all students have completed the quiz, I ask them to examine the posters made by their classmates two classes ago. I will have graded these posters and put them on the bulletin board before this class period. As they look at the posters, I ask each student to fill out Poster Scavenger Hunt, to keep them looking closely at the work of their peers.

The point of this activity is to honor the work completed by groups in an earlier class and reinforce the idea that not all distributions are appropriately modeled with the normal model [MP4]. Today, it also gives students the opportunity to move around quietly after the quiz.
