For a science project, Denise recorded the temperature of a nearby pond each day.

Pond temperature (°F)
65
67
69
71
73
75
What was the median temperature of the pond?

1 answer

To find the median temperature of the pond, we first need to arrange the temperatures in ascending order, which they already are:

  • 65°F
  • 67°F
  • 69°F
  • 71°F
  • 73°F
  • 75°F

Since there are 6 temperatures (an even number), the median will be the average of the two middle numbers. The middle numbers in this case are the 3rd and 4th numbers:

  • 3rd number: 69°F
  • 4th number: 71°F

Now, we can calculate the median:

\[ \text{Median} = \frac{69 + 71}{2} = \frac{140}{2} = 70°F \]

Therefore, the median temperature of the pond is 70°F.
