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?
°F

1 answer

To find the median temperature, you need to arrange the temperatures in order from least to greatest and then find the middle value.

The recorded temperatures are:

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

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

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

Now, calculate the average of these two values:

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

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