This lesson is the third lesson in the Descriptive Statistics Unit. The students will be exposed to key vocabulary terms. The students will use data collected in class and find the mean,median,standard deviation and IQR of the data set. They will also interpret these values. 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 is included but it is a continuation of the previous assignments in the lesson Displaying Quantitative data. 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.
