Difficulty: Easy
Category: Problem Solving and Data Analysis/-Scatterplots
Getting to the Answer: The range of a set of data points is the set of outputs, which correspond to the y--values of the data points on the graph. To find the maximum value in the range of the data, look for the highest point on the graph, which is (250, 85). The y-value is 85, so 85 is the maximum value in the range.
