The standard
Describe the impact that inserting or deleting a data point has on the mean and the median of a data set. Create data displays using a dot plot or box plot to examine this impact.
Element 6.NR.2.6 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Numerical Reasoning strand. It sits under standard 6.NR.2: Apply operations with whole numbers, fractions and decimals within relevant applications.
What students practice
Students select the statements that stay true after a far value is added to a small data set: the mean goes up, the median goes up, and the mean moves more than the median does. They do not create a dot plot or a box plot on this review.
