Identify the upper quartile of the data illustrated in the box-and-whisker plot.
A box and whisker plot is shown. A number line graph with a green rectangle extending from negative 3.5 to negative 0.5 above the line. There is a green dot at each end of the rectangle. There is a vertical line inside the rectangle at negative 2 with a red dot on it. There are black dots to the right and left of the green rectangle at 1 and negative 5. These black dots are connected to the green dots at their end of the green rectangle with black line segments.

In a box-and-whisker plot, the upper quartile (Q3) is represented by the right edge of the green rectangle (the box).
From your description, the green rectangle extends from -3.5 to -0.5, and the vertical line inside the rectangle is at -2. Since the upper quartile is the upper boundary of the box, it is at -0.5.
Therefore, the upper quartile of the data illustrated in the box-and-whisker plot is -0.5.
