... Ex. When comparing the difference between driving speed of an individual in the morning as opposed to the evening a random sample was conducted to choose 100 individuals. Each individual was then observed and a morning driving speed and an evening driving speed were calculated. The differences of ea ...

... 14. An environmentalist group monitors the temperature rise in the water 50 yards downstream from a nuclear power station. Federal regulations permit a rise in temperature of 3.0°F. They collect 16 water samples and obtain a mean rise of 3.2°F with a standard deviation of 1.0°F. Does this show that ...

Point Estimator
... If there are two unbiased estimators of a parameter, the one whose variance is smaller is said to be relatively efficient. E.g. both the the sample median and sample mean are unbiased estimators of the population mean, however, the sample median has a greater variance than the sample mean, so we cho ...
