## STEM Lessons - Model Eliciting Activity

In this Model Eliciting Activity, MEA, students will use data to decide the ideal candidate for a college scholarship by computing the mean and the standard deviation. The student will present the data using the normal distribution and make recommendations based on the findings. Students will recognize that not all data can be presented in this format.

Model-Eliciting-Activities, MEAs, allow students to critically analyze data sets, compare information, and require students to explain their thinking and reasoning. While there is no one correct answer in an MEA, students should work to explain their thinking clearly and rationally. Therefore, teachers should ask probing questions and provide feedback to help students develop a coherent, data-as-evidence-based approach within this learning experience.

## MFAS Formative Assessments

Students are asked to select a histogram for which it would be appropriate to apply the 68-95-99.7 rule.

Students are asked to scale and label a normal curve given the mean and standard deviation of a data set with a normal distribution.

Students are asked to find the probability that an outcome of a normally distributed variable is greater than a given value.

Students are asked to find the probability that an outcome of a normally distributed variable is between a standard deviation level.

## Problem-Solving Tasks

This problem solving task challenges students to answer probability questions about SAT scores, using distribution and mean to solve the problem.

Type: Problem-Solving Task

The purpose of this task is to have students complete normal distribution calculations and to use properties of normal distributions to draw conclusions.

Type: Problem-Solving Task

This task requires students to use the normal distribution as a model for a data distribution. Students must use given means and standard deviations to approximate population percentages.
