Amber would likely want the teacher to use the median as the measure of center for her report card grade. This is because the median is not influenced by extreme values, such as a particularly high or low grade on one test or assignment. As a result, the median provides a more accurate representation of Amber's overall performance and is less likely to be skewed by outliers. Amber would probably want her grade to reflect her consistent performance throughout the semester, rather than being overly influenced by any one exceptional result.
