This is the 12th lesson in the Probability Unit. In this lesson students will explore sampling distributions. Students will calculate the mean and standard deviation of a sampling distribution. Students will discuss how the sampling distribution is affected by the shape of the population and sample size. They will determine if a sampling distribution is approximately normal, and last they will use normal approximation to calculate probabilities. These lessons are set up to have the teacher lead the students through the note-taking process while incorporating examples for the students to try. The answer keys are provided with the pages numbered. Homework will be added shortly at not additional cost to those who purchase before. I will also be making videos that take the student through the lesson for those that flip their classroom or for absent students. SMART notebook files are included for the teacher to fill in with the class.
