The low temperatures during one week in January were 2° , −3° , −9° , −11° , 1° , −8° , and −9° . What was the median low temperature that week?

To find the median low temperature, we first need to arrange the temperatures in numerical order:

-11°, -9°, -9°, -8°, -3°, 1°, 2°

Since there are seven temperatures, the median will be the fourth temperature when arranged in order.

Therefore, the median low temperature for that week was -8°.
