Understanding Normal Distribution in Statistics Education
Lesson resources for teachers to teach students about analyzing and understanding normal distribution in statistics. Includes learning standards, agenda, presentation, vocabulary activities, and additional resources. Emphasizes using mean and standard deviation to fit data to a normal distribution, estimating population percentages, and recognizing when such procedures are inappropriate. Encourages the use of calculators, spreadsheets, and tables to estimate areas under the normal curve. Aligns with Common Core Standards and promotes mathematical practices. Prerequisite skills and focus areas for middle and high school students are also outlined.

Algebra 2 Statistics Normal Distribution Unit 5
Purpose Provided is a lesson for teachers to use to help students understand and analyze normal distribution. Included are the following: Statistics and Probability Learning Progression Standards Lesson Agenda Getting Ready for the Lesson (Resources and Tips) Lesson (Presentation and Video) Vocabulary Activities Textbook Connections Additional Resources
Common Core Standards S S- -ID.4. ID.4. Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

Normal Distribution Planning for Instruction with understanding Normal Distribution
Getting Ready O Pre-assessment- used to determine understanding of prerequisite skills O Prerequisite skills include O 6.SP 2-3 O 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. O 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 O 6.SP 5 O Summarize numerical data sets in relation to their context
Misconceptions and Anticipated Issues Common Issues Common Issues Suggested Strategies/Resources Suggested Strategies/Resources a. Use the additional practice worksheets from learnzilllion lesson b. Use more than 1 vocabulary organizer to address key vocabulary c. Allow students to use a calculator d. Analyze the graph and understand the standard variation vs mean a. Using the wrong total from the frequency table b. Misunderstanding the graph c. Wrong interpretation of mean or median d. Incorrect calculations for standard deviation
