Question

A scatterplot shows the number of hours studied versus test grade. The horizontal axis shows the number of hours studied, ranging from 0 to 10 in increments of 1. The vertical axis shows the test grade, ranging from 0 to 100 in increments of 5, starting with a jump from 0 to 35. A kink is shown on the vertical axis close to origin. A dot is plotted at 0.5 on the horizontal axis and 45 on the vertical axis. A loosely packed cluster of data plots is plotted between 1 to 4.5 on the horizontal axis and 77 and 98 on the vertical axis. A math teacher gave a math test. Interpret the scatterplot to determine which point is the outlier.(1 point)Responses(2.5,87) left parenthesis 2.5 comma 87 right parenthesis(1,78) left parenthesis 1 comma 78 right parenthesis(0.5,45)

Answer 1

The outlier is (0.5, 45). It lies far below and away from the main cluster (hours 1–4.5 with grades ~77–98), so its grade is unusually low for the pattern.
