Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
Guided Notes →One page your students fill in and keep.
Exit Ticket →Three items at the end of class. No student accounts.
Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
Homework →Assign practice; it grades itself.

"For quantitative variables, calculate, compare, and interpret mean, median, and range." "Compare distributions using measures of center and spread, including: • distributions with different means and the same standard deviations. • distributions with different standard deviations."

"Compare distributions using measures of center and spread, including:
• distributions with different means and the same standard deviations.
• distributions with different standard deviations."

What you'll learn

Compare two distributions with one statement about center and one about spread (the range, the interquartile range or the standard deviation), and interpret each in context
Calculate the range of a data set from a list, frequency table, dot plot or box plot, bound it from a histogram, and calculate the interquartile range from a box plot
Describe standard deviation as the typical distance of the values from the mean, and decide from lists or displays which of two standard deviations is larger without calculating either
State how adding the same number to every value changes the mean, median, range, interquartile range and standard deviation
