A meteorologist recorded the following temperatures: {71,74,81,78,67,69,64}. Which best describes the variability of the temperature.
A. The range is relatively low, indicating a low variability in the temperature.
B. The IQR is 11, indicating a fairly high variability for the temperatures for half of the recorded days.
C. The IQR 17, making the temperatures easy to predict because the data values are close together.
D. The range is relatively high, showing that the temperature will likely be as low as 47 degrees in the next temperature reading.
