Question

The temperature of earth may be measured either by thermometers on the ground, which is an accurate but tedious method, or by sensors mounted in a space satellite, which is a less accurate method. Researchers wanted to estimate how big of the differences are between the two methods. Researchers selected 20 sites randomly and measured the temperatures by both methods for each site at the same time periods.
Required:
What statistical inference method is the most accurate to estimate the difference?

Answer 1

Answer:

Analysis of variance (ANOVA) is the most accurate to estimate the difference

Step-by-step explanation:

Analysis of variance (ANOVA) is the best statistical method that can be used to determine the systematic difference between the mean values of two given set of population in any random experiment

In this case the two set of populations would be the one in which temperature is measured by thermometers on ground and sensor mounted in a space satellite.
