Be familiar with percentiles, the value of a variable below which a certain percent of observations fall. So the 45th percentile is the value (or score) equal to or below which 45 percent of the observations may be found and 55 percent are found above it.

There will be the assessment on Unit 1, Lesson 2, measures of center, on Friday. Be able to create and interpret the stem and leaf plots(including back-to-back stem and leaf plots), number line plots, and histograms. Mean, Median, and Mode should be able to be found and interpreted. Understand sensitivity/resistance to changes in outliers for mean and median.
